Problem #1: Galaxy S6 turns off on its own when battery has 30% | Galaxy S6 overheating, takes long time to charge | Galaxy S6 very slow

The past 2 weeks my Galaxy S6 has been acting up. I read about the soft reset but I can’t get to my battery. My phone has been dying very quickly through the day when normally it will last me all day long. I’m not really on my phone that much until after school but when I get out of school my phone is at 30 or less %. And my phone will sometimes say I have 9% and then goes straight to 3% then I plug it in at 3% and it dies as soon as I plug it in. I used to have a fast charger but the one I’ve been using for awhile now isn’t, and sometimes I will use a wireless charger.

My phone has also been over heating a lot even when I’m not using it. In the recent 2 weeks, I plug in my phone and it says it’s going to take 6 and a half hours in order to fully charge when before it didn’t take but 2 hours.

My phone has also been glitching from time to time and has become a lot slower than normal. I have tried other outlets than the one I use most of the time and one outlet will say 6 and half hours and then the other tells me 2 and half. I have had this phone for over a year, but not sure what’s going on and whether I need a new battery or a new phone. — Danielle

Solution: Hi Danielle. To know whether the problem is due to a software glitch or bad hardware, you must do a series of troubleshooting steps.

The first one is to see if battery recalibration will help. Sometimes, Android can lose track of the actual battery level causing the phone to reboot prematurely even if the battery percentage is showing high figure. To fix the issue, you must do some steps to help the operating system detect the true remaining battery power. Here’s how:

  1. Use the phone by playing games or doing tasks to hasten power discharge, until the phone turns itself off.
  2. Turn the phone on again and let it turn itself off.
  3. Charge the phone without turning it back on.
  4. Wait until the battery says it fully charged to 100%
  5. Unplug the charger and turn the phone on.
  6. If the phone says it’s not 100% anymore, turn it off, plug the charger back in and wait until 100% charge is reached.
  7. Unplug the charger the turn the phone on again.
  8. Use the phone until you drain the battery down to 0.
  9. Repeat the cycle once.

Observe the phone for a few days to see if battery calibration will improve the situation. If the phone continues to shut down randomly and drain battery power fast, the next troubleshooting step to do is factory reset. This troubleshooting step is meant to eliminate any software glitch that may be causing all the problems. Factory reset returns all software settings to their defaults, effectively removing any glitch that may have developed after you unboxed the phone. To do that, follow these steps:

  1. Turn off your Samsung Galaxy S6 Edge.
  2. Press and hold the Volume Up, Home and Power keys together.
  3. When the device powers on and displays ‘Power on logo’, release all keys and the Android icon will appear on the screen.
  4. Wait until the Android Recovery Screen appears after about 30 seconds.
  5. Using the Volume Down key, highlight the option, ‘wipe data/factory reset’ and press the Power key to select it.
  6. Press the Volume Down button again until the option ‘Yes — delete all user data’ is highlighted and then press the Power key to select it.
  7. After the reset is complete, highlight ‘Reboot system now’ and hit the Power key to restart the phone.
  8. Observe the phone for at least 24 hours. Make sure not to install any app or update during this time.

If you observe the same problems after a factory reset, you can assume that bad hardware is the culprit. It can be a battery issue too so if possible, try to buy a new one and use it on your phone.

Should nothing change, simply send the phone in so its hardware can be checked and determined if it needs repair.

Problem #2: Galaxy S6 edge plus keeps showing “not charging” notification even when it’s not connected to charger

Greetings. I have started getting an issue on a S6 edge plus. It all began when i plugged in the device to be charged on a 5v 2A (the ones that come in the extension cords as a usb charging hub). As soon as i plugged it in, the phone went into VR mode and then blank. After that, i unplugged it and connected the original charger and that closed the VR mode screen and it went back to “normal.” However i keep getting a notification pop up saying “not charging” which is obvious as the device is not connected to any source of power. I think that’s all i got for you guys. Hope this info will help you so that you can help me. Thanks in advance. — Pablo

Solution: Hi Pablo. We think you need to ensure first that this is not a software issue. You can do that by doing a factory reset so you can compare how the phone behaves when the software is returned to its known, working state. Be sure that you don’t install anything so as to preserve the original software state during the observation period.

If “not charging” notification continues to popup, it can only be due to a malfunctioning hardware. The charging port must have been damaged for some reason, triggering the notification to popup even when the device is not being charged. In this case, you must send the phone to Samsung so it can be repaired or replaced.

Problem #3: Galaxy S6 won’t charge and turn on

Galaxy S6 won’t charge or turn on. I see the Lightning icon but nothing else happens. Things to note acted weird when I plugged it in last. It was dead but when I plugged it in it said 94% charged. This morning it was at 4% after being plugged in all night. Once it shut off and I attempted to turn it back on a yellow triangle with an explanation point in it along with the android man beneath it appeared. I believed it said rebooting a bunch of words appeared like it was rebooting then the phone shut off and never turned back on. Like I said I can see the charging symbol but nothing else. —Joellen80

Solution: Hi Joellen80. The only troubleshooting step that you can do in this situation is to see if you’ll be able to restart the phone to alternate modes. Only then can you do follow-up troubleshooting. If your phone remains dead, you must seek the help of a professional or Samsung so your hardware can be examined.

For reference, here are the steps on how to boot your S6 to other modes and their follow-up troubleshooting that you can do:

Boot in Recovery mode:

  1. Charge the phone for at least 30 minutes.
  2. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  3. When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  4. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  5. Using the Volume Down key, navigate through the options and highlight ‘wipe cache partition.’
  6. You can either wipe the cache partition or do a factory reset when in this mode.

Boot in Download Mode:

  1. Charge the phone for at least 30 minutes.
  2. Press and then hold the Home and Volume DOWN keys, then press and hold the Power key.
  3. When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume DOWN keys.
  4. Wait until the Download screen appears.
  5. If you can boot the phone in download mode but not in other modes, that means that your only way out may be to flash a stock or custom firmware.
  6. Use Google to look for a guide on how to do it.

Boot in safe mode:

  1. Charge the phone for at least 30 minutes.
  2. Press and hold the Power button.
  3. Once the ‘Samsung Galaxy S7’ logo appears, release the Power key and immediately press and hold the Volume Down button.
  4. Continue holding the button until the phone finishes rebooting.
  5. Once you see the text “Safe mode” at the bottom left corner of the screen, release the Volume Down button.
  6. The only difference of safe mode from normal mode is that the former prevents third party apps from running. If you can boot the phone in safe mode but not in normal mode, uninstall all apps until the issue (that prevents you from booting normally) is eliminated.

Problem #4: Galaxy S6 takes a very long time to charge | Galaxy S6 fast charge not working

Previously when i plug the charger, it give me approximately 2 hours max to fully charge my battery. Suddenly it started giving me 6 hours. I tried to clean the USB thing and i tried switching to safe mode to see if any of the third party apps are the cause but it kept giving me 6 hours to fully charge. I tried the sysdump also and turned the low battery dump on but nothing worked.

Note: it’s not from the charger since my brother has a S6 edge also and it charges perfectly for him and i tried a lot of charges. they work for others but for me they are toooo slow. What should i do? — Toola.me1

Solution: Hi Toola.me1. If you’ve already tried  factory reset and charging remains slow, there must be something wrong with the hardware. It can be a faulty charging port. Try to inspect the charging port for dirt or bent pins inside. Sometimes, they can cause erratic charging behavior so if you see anything amiss inside, that may be the cause of the problem. Most of the time, charging port damage occurs beyond the visible part so you must have the phone examined by Samsung or an independent service center.

Other power- and charging-related issues can be caused by a bad power IC in the logic board. Again, the phone has be physically checked by a technician to know this. The general rule is to try all relevant software troubleshooting such as wiping of cache partition, observing in safe mode, and factory reset. If nothing will change after doing such steps, send the phone in for repair.

Problem #5: Galaxy S6 Message+ app keeps crashing

Hello. Every time I have attempted to open the messaging app in the last hour it fails to work and only a white screen shows up with a red bar at the top. After about 5 minutes a message shows up saying, “Message+ isn’t responding. Do you want to close it?” Leaving me the choice to either report, leave or ok. I click ok every time and I’ve gone to extremes in attempting to make it work including deleting all of the apps that didn’t come with the phone to frequently restarting it. That’s it. Please tell me how to fix my problem. — Maddy

Solution: Hi Maddy. Try wiping the app’s cache and data first. Doing so is the virtual equivalent of uninstalling and reinstalling the said app. Here’s how it’s done:

  1. Open the Settings menu either through your notification shade (drop-down) or through the Settings app in your app drawer.
  2. Navigate down to “Apps”. This may be renamed to something like Applications or Application Manager in OEM skinned versions of Android 6.0.
  3. Once in there, click on an application.
  4. You’ll now see a list of stuff that gives you information about the app, including Storage, Permissions, Memory Use, and more. These are all clickable items. You’ll want to click on Storage.
  5. You should now clearly see the Clear Data and Clear Cache buttons for the application.

If this troubleshooting step will not fix the issue, you can then try to factory reset the phone. If we are not mistaken, Message+ is a Verizon messaging app so restoring the original version of the firmware may eliminate the bug. To factory reset your S6, follow these steps:

  1. Create a backup of your important files.
  2. From the Home screen, tap the Apps icon.
  3. Find and tap the Settings icon.
  4. Under the ‘Personal’ section, find and tap Backup and reset.
  5. Tap Factory data reset.
  6. Touch Reset device to proceed with the reset.
  7. Depending on the security lock you used, enter the PIN or password.
  8. Tap Continue.
  9. Touch Delete all to confirm your action.

Finally, if the issue remains after a factory reset, contact the developer for support.

Problem #6: Galaxy S6 overheating and lagging due to bad hardware

My phone is overheating way too much and way to quick. It has started up recently. i haven’t downloaded any new app or anything.

I have restarted the phone but no luck. When i start to charge it, it heats up even quicker and now i am starting to have problems with its performance like it crashes a lot. Once it’s hot it slows down. The touches on my screen don’t work properly. No clue what it could be. i have tried cooling apps but they don’t work so i delete them. i don’t know what to do. My phone is a Samsung S6 edge. Please could you help me with this thank you. — Zulaikhah

Solution: Hi Zulaikhah. Like what we tell others above, you must do a factory reset first and proceed from there. This is the only way to determine whether you can fix the issue on your end or not. We do think hardware malfunction is to blame. Taken together with other symptoms you mention, the overheating issue must be caused by a failing component. What that component is is for a technician to know and to do that, the phone must be physically checked. Be sure to send the phone to Samsung or to an independent repair shop so the hardware can be examined thoroughly.

Problem #7: Galaxy S6 won’t work if not connected to a charger

Hi. I have a Samsung S6. i bought it around 3 months ago. Here is the problem: yesterday, i noticed it had turned itself off despite having 70 percent battery. i turned it back on a few times it comes on then just goes off again. however if i connect the charger it will stay on. I’ve also noticed it will say 100 percent charged, then when i unplug it, it reads something like 70 percent. Can you help please? — Des

Solution: Hi Des. An issue like this is almost always  due to a bad battery issue.

Try doing a battery calibration first and see how it goes. If there’s no change, proceed to factory reset. If a reset won’t work either, find a way to have the phone repaired or replaced. Steps on how to recalibrate the battery and factory reset are provided above.

Problem #8: Galaxy S6 stops working after changing its IMEI

Well, I got this Galaxy S6 that first I locked and I forgot the back up password and I try to reboot but ended up deleting the whole software. So I took it in to a shop and I guess they were being honest and told me they just get it to work and ended up installing a whole new software and gave the phone a new IMEI. Now the phone won’t work and the original IMEI work but the new one is blacklisted and seem like no one can fix it. — Luis

Solution: Hi Luis. Well, the only people that can help you are the ones who modified the software in the first place. Only them knows what things they did on the device. We can’t see the logic of modifying the IMEI when the original problem is about unlocking the phone only so there must be an underlying reason for them to do it.

We also don’t know what exactly you mean by your “phone won’t work” phrase. If you can get back to us giving us more details, perhaps there’s something that we can suggest.

Galaxy Note 5 Samsung keyboard settings changed after installing update, other issues

Good day Android users and welcome to another #GalaxyNote5 article. In this post, we’re bringing you 10 more issues that were reported to us by some Note 5 users for the last few days. We hope that you’ll find this article useful.

If you are looking for solutions to your own #Android issue, you can contact us by using the link provided at the bottom of this page.

When describing your issue, please be as detailed as possible so we can easily pinpoint a relevant solution. If you can, kindly include the exact error messages you are getting to give us an idea where to start. If you have already tried some troubleshooting steps before emailing us, make sure to mention them so we can skip them in our answers.

Below are specific topics we’re bringing for you today:

Problem #1: Galaxy Note 5 screen doesn’t wake up when it’s fast charging

Hi Admin. I own a Samsung Note 5 N9028 Dual SIM 32GB, purchased in Feb 2016 ( a year and 4 months old). I am facing this issue since Nougat. The thing is, my phone, when kept at fast charging, doesn’t wake up from sleep, although the notification light, home key, back key works fine. I can even answer the call if I swipe in the right place on the screen. But if I keep in normal charge mode, I don’t face this issue. Initially I though fast charge was the issue, but since past few days the screen doesn’t display when I unlock for no reasons. I tried to diagnose the reasons:

  1. May be due to extreme light ( sun light on street) or low light( dark at night) – light sensor issue
  2. May be due to some firmware update issue – Tried factory reset and even ROM reset by Samsung service center
  3. May be due to hardware issues in display where the screen power management chip is corrupted ( But the frequency of this issue is not increasing – Its TOTALLY RANDOM, once per day to even 10 times per day).

May I know if you have come across this issues in any other galaxy devices. Server center says I have to replace the screen, but they don’t guarantee me the solution. They don’t even know why it’s happening. I believe it has something to do with the update.

ALSO, ONCE IT HAPPENED, I HAD KEPT IT FOR CHARGING WITH PHONE TURNED OFF. I COUDNT EVEN SEE THE CHARGING METER AND THE GREEN BLINKING ON THE SCREEN – SO I AM WORRIED IF ITS ACTUALLY A HARDWARE ISSUE. — Dipak

Solution: Hi Dipak. We’ve already handled thousands of issues from different Android devices but it’s our first time to hear your situation so it’s probably an isolated case. If you’ve already tried a factory reset before without any positive result, then Samsung service center may be right in their suspicion that it’s a hardware issue. We don’t have enough information about your phone and its history to say for sure what’s causing this problem. We don’t think it’s the screen though so it’s up to you if you plan on following Samsung’s recommendation to have it replaced. For us, it’s better if you simply have the phone replaced.

Problem #2: Galaxy Note 5 not receiving SMS from other carriers, only from T-Mobile

Ok here it goes. I have a Galaxy Note 5 that is unlocked. Originally it was from Verizon but I switched to Sprint. I had it unlocked and went to straight talk until I decided on a carrier. I chose T-Mobile. On May 5, 2017 I backed up what I needed and did a factory reset. Everything is ok except receiving text messages (SMS). I receive them from ironically T-Mobile customers but no other carriers. T-Mobile support suggested something about the service center number. I go through the messages app settings and look for this number but it’s not there. WTF did I do? I need to be able to receive all carriers messages. Any help would be greatly appreciated. — John

Solution: Hi John. There a number of things that you need to check to narrow down the causes of your problem but we think the cause of the problem is rooted in your T-Mobile account. If you can only receive SMS from T-Mobile users, then it’s most probably not a device issue. You must work with T-Mobile to fix the problem.

As far as device troubleshooting is concerned, these are the items that you should check:

  1. Is call barring active? This is usually enabled by your carrier so you must work with them to check it.
  2. Make sure the messaging app’s inbox is not full.
  3. Check if it’s a SIM card problem by inserting your card in another device. If the issue persists even when your SIM card is inserted in another phone, that’s proof that you have an account issue. This is the type of problem that only your carrier can fix so contacting us about it is of no use.
  4. If you want to check the Message Center number, you can do it by going under the settings menu of your messaging app. The exact steps vary, especially if you’re not using the native Samsung messaging app.

Problem #3: Galaxy Note 5 regularly freezing, lagging

My Samsung Galaxy Note 5 is constantly freezing up for a couple of seconds then goes back to normal. It’s extremely annoying! Typing takes twice as long, because I have to wait for the freeze to end and my words to catch up, or retype them all together. Listening to anything, whether video or music, is almost impossible because every few seconds, (if I’m lucky, every couple of minutes) all sounds cuts out, if a video, then it freezes too, but then it cuts back in, then cuts back out, then in, then out…..I don’t know if it’s a lag, or just that it’s freezing then unfreezing. Please help me. — Star.shine070413

Solution: Hi Star.shine070413. An issue like this is almost always caused by bad hardware so you’ll most likely end up with either a repair or a replacement. To check if that’s the case, you must do all the basic Android software troubleshooting.

Wipe the cache partition

The first one is wiping of the cache partition. Sometimes, apps can behave erratically if the system cache, which is stored in special partition called cache partition, is corrupted. This usually happens after installing a system update. To fix the issue, you must delete the old system cache so the device will be forced to create a new one. Here are the steps to do that:

  1. Turn off your Samsung Galaxy Note 5 completely.
  2. Press and hold the Volume Up and the Home buttons first, and then press and hold the Power key.
  3. Keep the three buttons pressed and when ‘Samsung Galaxy Note5’ shows, release the Power key but continue holding the other two.
  4. Once the Android logo shows, release both the Volume Up and Home buttons.
  5. The notice ‘Installing system update’ will show on the screen for 30 to 60 seconds before the Android system recovery screen is shown with its options.
  6. Use the Volume Down key to highlight the option ‘wipe cache partition’ and press the Power key to select it.
  7. When the process is complete, use the Volume Down key to highlight the option ‘Reboot system now’ and hit the Power key to restart the phone.
  8. The reboot may take a little longer to complete but don’t worry and wait for the device to become active.

Observe the phone in safe mode

If you are the type who tends to install apps without considering where they come from, or whether they’re from a good developer, one of the installed apps may be causing the problem. To see if that’s the case, you want to boot the device to safe mode and observe the phone for a few hours to see any difference. Here are the steps on how to start your Note 5 to safe mode:

  1. Turn off the phone completely.
  2. Press and hold the Power key.
  3. Once ‘Samsung Galaxy Note5’ shows, release the Power key and immediately press and hold the Volume Down button.
  4. The phone will restart but keep the Vol Down button pressed.
  5. Once the phone has finished restarting, ‘Safe mode’ will be display in the lower-left corner of the screen.
  6. You may now release the Volume Down button.

Revert all software settings to defaults with factory reset

If both procedures above won’t change anything, you should then consider a more drastic step by converting the phone into a clean slate via factory reset. This will erase all user data and customizations as well as all the apps you installed so if the cause of the problem is software related, the phone should work normally again without lag. Here are the steps on how factory reset your Note 5:

  1. Create a backup of your important files such as photos, videos, contacts etc. You can use Smart Switch for this task.
  2. Turn off your Samsung Galaxy Note 5 completely.
  3. Press and hold the Volume Up and the Home buttons first, and then press and hold the Power key.
  4. Keep the three buttons pressed and when ‘Samsung Galaxy Note5’ shows, release the Power key but continue holding the other two.
  5. Once the Android logo shows, release both the Volume Up and Home buttons.
  6. The notice ‘Installing system update’ will show on the screen for 30 to 60 seconds before the Android system recovery screen is shown with its options.
  7. Use the Volume Down key to highlight the option ‘Yes — delete all user data’ and press the Power key to select it.
  8. When the process is complete, use the Volume Down key to highlight the option ‘Reboot system now’ and hit the Power key to restart the phone.
  9. The reboot may take a little longer to complete but don’t worry and wait for the device to become active.

Send the phone in for repair or replacement

If all three software troubleshooting steps above won’t help, contact the relevant party that can repair or replace your phone.

Problem #4: Galaxy Note 5 can’t play videos properly

When I am watching a video it will pause the video, rewind the audio about 10 seconds, and then play the audio until it catches up with the video, then the video continues to play. Sometimes it creates a loop and just plays the same 10 seconds of audio over and over. It has occurred with several different apps. — Anthony

Solution: Hi Anthony. Try wiping the cache partition first and observe how video works afterwards. If that won’t fix the problem, do a factory reset.

Problem #5: Galaxy Note 5 Samsung keyboard settings changed after installing update

I installed the latest software update last night. Now my text messaging has no auto correct. It also doesn’t automatically capitalize the first word of a sentence or put a period in if i hit the space bar twice. I can not find anything in settings to correct this problem. Any help you can give me would be greatly appreciated. — Ktfrog100

Solution: Hi Ktfrog100. We’re assuming your Note 5 is now running Android Nougat (Android 7). If that’s the case, here are the steps on how to enable the keyboard features you’ve lost:

  1. Open the Settings app.
  2. Scroll down to General management and tap it.
  3. Tap Language and input.
  4. Tap Virtual keyboard.
  5. Tap Samsung keyboard.
  6. Enable Predictive text, Auto check spelling, Auto capitalize, and Auto punctuate.

The steps above should also be more or less the same if you running the older Android Marshmallow.

Problem #6: Galaxy Note 5 shutting off at random

My phone began shutting down randomly. Now it rarely starts at all and if it does it shuts down shortly afterwards. I have a replacement phone coming but I need to erase any banking and personal information first if possible. I assume I’ll lose any pictures etc that I haven’t backed up. Thank you for any assistance you can offer me. — Dave        

Solution: Hi Dave. The only way to wipe your phone clean is by doing a factory reset via Settings or Recovery mode. You can’t do either of them when your phone won’t stay on long enough to do steps for each. Try connecting the phone to a charger before attempting to factory reset it to see if that will make a difference. If you can’t let the phone stay powered on long enough to perform a factory reset, you’re out of luck. Below are the steps on how to factory reset your phone via Settings:

  1. From the Home screen, tap the Apps icon.
  2. Find and tap the Settings icon.
  3. Under the ‘Personal’ section, find and tap Backup and reset.
  4. Tap Factory data reset.
  5. Touch Reset device to proceed with the reset.
  6. Depending on the security lock you used, enter the PIN or password.
  7. Tap Continue.
  8. Touch Delete all to confirm your action.

Problem #7: Galaxy Note 5 can’t create another album or transfer files to another album after Nougat update

Just updated to Nougat last week. Can’t move pictures to another album and can’t create album either. Hope you can help. Thanks! (I already tried resetting and clearing data and cache on the gallery app.) — Zarah

Solution: Hi Zarah. Make sure that you also wipe the cache partition and install updates for all your apps. If you’ve already did them beforehand, consider doing a factory reset to eliminate possible software bug causing the problem. Kindly refer to the steps above on how to wipe the cache partition and factory reset.

Problem #8: Galaxy Note 5 can’t make calls when wifi or wifi calling is enabled

After the Nougat 7 update, I am unable to make outgoing phone calls when connected to WiFi AND WiFi calling. I have it defaulted to “prefer” mobile network connection for phone calls but I never had an issue before this update. All I used to do was unselect the WiFi calling option and be done. That’s not the case now. Thanks for the help! — Ashley

Solution: Hi Ashley. The first thing that you need to do is to wipe the cache and data of the wifi calling app. This will ensure that you revert all its settings back to its defaults. Here’s how to do that:

  1. Open the Settings menu either through your notification shade (drop-down) or through the Settings app in your app drawer.
  2. Navigate down to “Apps”. This may be renamed to something like Applications or Application Manager in OEM skinned versions of Android 6 or 7.
  3. Once in there, click on an application.
  4. You’ll now see a list of stuff that gives you information about the app, including Storage, Permissions, Memory Use, and more. These are all clickable items. You’ll want to click on Storage.
  5. You should now clearly see the Clear Data and Clear Cache buttons for the application.

Should the issue remain after clearing cache and data on wifi calling, try wiping the cache partition (steps provided above). If that won’t work either, consider wiping the phone clean with factory reset. These three are the only applicable device troubleshooting that you can do in this case.

You should contact your carrier for more assistance if you can’t solve the issue yourself.

Problem #9: Galaxy Note 5 makes no sound notification during calls after Nougat update

I’ve a Samsung Galaxy Note 5. But after the Nougat update I’ve noticed that the phone don’t ring when someone calls. Despite its not on silent mode. I’ve to restart the phone to fix this. I’ve also done a factory reset but the problem is still there. — Shenoda

Solution: Hi Shenoda.  If a factory reset did not fix the problem, the problem is probably being caused by one of the apps you re-installed. Try observing the phone while it’s on safe mode for a few hours so you can try to replicate the problem. Safe mode prevents third party apps and services from running so if notification works while your Note 5 is booted to safe mode, that’s proof that one of the third party apps is the cause. You must uninstall apps until the issue is eliminated.

Problem #10: Galaxy Note 5 won’t turn back on after it was physically impacted

At an event this weekend while packing up to leave, I was walking on a gravel down hill surface. I slipped and ended up falling on my backside. Phone unfortunately was in my back pocket. I had taken some videos earlier in the day but the phone still had at least 70% charge. I didn’t try the phone until we were back home and it seemed to be completely dead. I noted that nothing happened when I plugged it in. Phone will not power up at all. Battery charge icon will not come up. phone has no visible damage and has an otter box case but I fear I may have smashed or disconnected something internally when I landed on it. Local T-Mobile store could not get it to boot either and tried all the “tricks”. I have some videos and info I really need from the phone that are now inaccessible. is there anything else i can try? They are going to warranty the phone with a new one but that doesn’t help me get my info back. I put “lolipop” for the software but I’m not really sure what it is. The phone is less than 2 months old. — Mikemorton922

Solution: Hi Mikemorton922. If your phone is dead and won’t respond to any hardware button combinations like the ones we provide above, there’s nothing more that you can do on your end. The motherboard or some critical components may have been permanently damaged by the unnecessary pressure applied to the phone. Access to the storage chip is only possible if (1) the motherboard is intact and (2) if you can still turn the phone back on. If any of these two is absent, your files are good as gone.

If you think recovery of your files is worth a few hundred dollars, consider bringing the phone to an independent service center so they can take a look at it. There’s no guarantee that they can turn the phone back on but it should still be worth it especially if the files are valuable.

Problem #1: Galaxy S7 stops booting normally after installing Android Nougat

I downloaded the latest update (Nougat) over night. In the morning, I let it do its thing. Went through the update screen (green with the gears) and about 20 minutes later it was done. It rebooted and basically have been stuck on this loop of phone turns on, “Android System Upgrading Android..” with the bar stuck at about the “a” in upgrading. Couple of minutes goes by, phone restarts, I’ll see the lock with the blue and green lines that make a circle, it comes back on. Later. Rise. Repeat.

Sometimes when it’s on, i’ll try and go to settings or another app and it’ll go to a screen like it’s loading and nothing comes up. Just a white screen. I have no clue what to do next. I can’t save off anything on my phone because it restarts or wont even let me open an app. Not even sure if the phone connects to the internet/wifi in case it needs to download more info. Thanks in advance for any help. — PT

Solution: Hi PT. Although most update installations proceed as normal, some users may encounter problems. Such problems are caused by a wide variety of possible causes. We don’t want to discuss the reasons why updates sometimes fail on some users but focus on what you can do on your end. Because your phone no longer boots normally, or doesn’t allow you to load an app, creating a backup is out of the question. In an ideal situation, you are supposed to create a backup before you installed the update to prevent losing important data when a situation like this arise. Because you failed to do that, there’s no way you can recover whatever user data you may have stored in the phone’s internal memory.

As far as solutions are concerned, the only effective ones that you can try to do in this particular case includes wiping the cache partition and factory reset. These two solutions require that you restart the phone to recovery mode first. For details on how to do each of them, kindly follow the steps below.

How to wipe Galaxy S7 cache partition

  • Turn off your Samsung Galaxy S7.
  • Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  • When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  • When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  • Using the Volume Down key, navigate through the options and highlight ‘wipe cache partition.’
  • Once highlighted, you may press the Power key to select it.
  • Now highlight the option ‘Yes’ using the Volume Down key and press the Power button to select it.
  • Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.
  • The phone will now reboot longer than usual.

How to factory reset your Galaxy S7

  • Turn off your Samsung Galaxy S7.
  • Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  • When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  • When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  • Using the Volume Down key, navigate through the options and highlight ‘wipe data / factory reset.’
  • Once highlighted, you may press the Power key to select it.
  • Now highlight the option ‘Yes — delete all user data’ using the Volume Down key and press the Power button to select it.
  • Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.
  • The phone will now reboot longer than usual.

Problem #2: Whatsapp keeps crashing on Galaxy S7 edge

I recently bought a new S7 edge from Dubai and on around the 23rd of February 2017, my WhatsApp crashed, in the sense that it opens for a fraction of a second and then closes. The data is all there and I keep getting chats from friends but i just can’t open it long enough to even open them. but if I am quick enough, I can access a chat or two after several tries. If someone sends me a message, it shows up in the status bar at the top of the phone and when I click on that, I can have a quick chat for a short time before it shuts down again. After many tries, I managed to get to the chat backup settings and managed to backup and change the setting to daily backup including videos. I backed up the phone and went to the Samsung store (when I got back to India) where they tried to reset the settings. When that didn’t work, they tried a factory reset. The gentleman restored the phone and Whatsapp but it didn’t change a thing. WhatsApp still refuses to stay open. It’s the newest update that they released.. With features similar to Snapchat. What do you suppose needs to be done here? Should I just ask the company to replace the phone? I’ve tried whatever options I could, at home and at the Samsung store. — Hayat

Solution: Hi Hayat. If this crashing issue only occurs when trying to use WhatsApp, that can be an indicator that the app itself is buggy, or that another app is causing to fail. To check if it’s the app itself that is causing the problem, there are two things that you can do.

The first one is to delete the app’s cache and data. Sometimes, an app’s cache can get corrupted or outdated so forcing the phone to create a new app cache may resolve the issue. Here’s how to do it:

  • Open the Settings menu either through your notification shade (drop-down) or through the Settings app in your app drawer.
  • Navigate down to “Apps”. This may be renamed to something like Applications or Application Manager in OEM skinned versions of Android 6.0.
  • Once in there, click on an application.
  • You’ll now see a list of stuff that gives you information about the app, including Storage, Permissions, Memory Use, and more. These are all clickable items. You’ll want to click on Storage.
  • You should now clearly see the Clear Data and Clear Cache buttons for the application.

The other thing that you can do is try another round of factory reset and observe how WhatsApp works when it’s the only third party app installed. This means holding off installation of other apps after a factory reset so you can check whether or not WhatsApp works or not. If it does, you can assume that one of the third party apps is interrupting Whatsapp app when it’s working. To know what app may be causing the issue is not straightforward and requires further troubleshooting. You must invest more time and effort in identifying it. Unfortunately, the only way to do that is by installing one app at a time and observing how WhatsApp works.

On the other hand, if the problem persists after a factory reset, even when it’s the only third party app installed, the cause must be something deeper. If possible, consider having the phone replaced to fix the issue.

Problem #3: Galaxy S7 edge can’t read new SD card

Hello. I am from Romania (Europe). I just bought a new Galaxy S7 edge. I bought a new SD card of 32GB and mount it, format it. I put on it music and I set the camera to save the photos on the SD card. After 2 days of use when I wanted to see a picture after making it with the camera it denied to open it. And the music wasn’t no where to find it in my phone. Then I understood my SD card was no longer appearing. I reset the phone and the music appeared again but no pictures. This is happening for a few days now. I lost all my pictures I made till now. I changed the SD card to an old one I had of 8GB that was working good. If it acts as the first one it means the problem is with the phone, right? Do I have to send it to be fixed? Thanks! — Loredana

Solution: Hi Loredana. Troubleshooting an issue like this is simple. If the problem won’t occur when using a second SD card (the old 8GB card), that’s a clear indicator that the new SD card is defective. To fix it, try to reformat it on your phone first. If that won’t work, simply discard it and get a new one (or use the old card).

If, the on other hand, the problem continues even with the old or new second SD card, try doing some basic software troubleshooting first as the cause may be caused by a third party app or an unknown software bug.

The first one that you must do is to wipe the phone’s cache partition to tell the phone to create a system cache. Kindly refer to the steps above on how to do this.

If wiping the cache partition won’t work, you can then try to see if a third party app is creating a conflict by restarting the phone to safe mode. Safe mode blocks third party apps and services so if your phone will read the SD card normally, you can assume that one of the apps is problematic. To restart your S7 to safe mode, follow these steps:

  • Turn your Galaxy S7 off.
  • Press and hold the Power button.
  • Once the ‘Samsung Galaxy S7’ logo appears, release the Power key and immediately press and hold the Volume Down button.
  • Continue holding the button until the phone finishes rebooting.
  • Once you see the text “Safe mode” at the bottom left corner of the screen, release the Volume Down button.

Finally, if the issue persists even when the phone is booted to safe mode, performing a factory reset may fix the issue. As the name suggests, factory reset will return all software settings to their defaults. It will also wipe all user data like photos, videos, music, etc. so make sure to create a backup before proceeding. Here’s how it’s done:

  • From the Home screen, tap the Apps icon.
  • Find and tap Settings and then touch Backup and reset.
  • Tap Factory data reset and touch Reset device.
  • If you have screen lock feature turned on, enter your password or PIN.
  • Touch Continue.
  • Tap Delete all to confirm your action.

Now, we think factory reset will fix this issue but if, for some reason, the problem remains, consider having the phone replaced.

Problem #4: Galaxy S7 froze when recording a video | Photos and videos disappeared after Galaxy S7 froze while recording video

I was recoding a video on my S7, it froze. After a short time I tried to reboot but it wouldn’t shut down. The screen was black the power key top left shine blue and the two either side of the home button were illuminated. After a few minutes it shut down and I was able to power on. I recorded another video, all seemed fine. The next day I went to look at my videos to discover all the photos and videos had disappeared. I am using a PNY micro SD card. I’ve tried a reboot again, nothing. I’ve also tried the SD card in a computer, nothing. I can’t get onto my Samsung cloud either. I’ve had the phone since 23 December 2016. Please can you help. Thank you. — Yvette

Solution: Hi Yvette. If a second device like a computer can’t find your files in the SD card, or doesn’t seem to detect the SD card either, that’s a sign that it may had failed or had been corrupted for some reason. Try inserting it in another phone and see what happens. If the third device won’t detect or read it either, you’re out of luck as those files must be gone. The best that you can hope for is to see if the SD card can still be used after reformatting it.

To format an SD card, do the steps below:

  • From home, tap Apps > Settings .
  • Tap Storage .
  • Tap SD Card > Format.
  • Tap Format to confirm.

For your Samsung cloud issue, the best that you can do is to follow Samsung’s system in recovering your account in this page. Click on the “Forgot your password” link, enter and confirm the email you used to register, then type in the validation code.

Problem #5: Galaxy S7 Messages app only receives SMS from iPhone users but not from Android users

I was using the Message+ app for texting and decided to switch to Samsung’s message app for texting instead. It works great except for one thing. I can send texts out to anybody, but the only messages I receive back are from people that have iPhone’s. Anybody I know that has an Android phone will send a text back to me and it will only go into the Message+ app not, the Samsung app. I have made sure that the Samsung app is my default app and I have also turned off the Message+ app to no avail. Any ideas on why this is happening and how it can be fixed? — Renae

Solution: Hi Renae. It’s an odd issue and we haven’t heard of it happening so it must be isolated to your device. There must be some misconfiguration in how the software handles SMS so kindly refer the problem to Verizon. We don’t work for Verizon so we have no data if this is a known bug, or if there’s a solution that you can do on your end. Contacting your wireless carrier may help you fix it.

Problem #6: Galaxy S7 email won’t sync due to password issue

My e-mail account won’t sync, even when I try to do so manually. I have tried turning on auto-sync, and it looks like the app is syncing but no new e-mails show up. It shows the last sync as several weeks ago. I tried re-booting, clearing the cache, everything. Nothing is working. I also tried going into the email server settings, but a message comes up that “A security connection error has occurred.” I tried re-entering my password, but that didn’t work, either. — Jean

Solution: Hi Jean. If your password doesn’t work at this time, that may be the reason why there’s a sync issue going-on. Make sure that you know the correct password of your email by logging in to your webmail first (by logging in using a browser instead of the email app). Once you’ve resolved your password issue, we’re confident that the sync issue will go away.

To be sure, reconfigure your email in the app after resolving the password issue. You can also try to wipe the cache and data of the email app if you want to ensure that there’s no bug that prevents it from syncing properly.

  • Open the Settings menu either through your notification shade (drop-down) or through the Settings app in your app drawer.
  • Navigate down to “Apps”. This may be renamed to something like Applications or Application Manager in OEM skinned versions of Android 6.0.
  • Once in there, click on an application.
  • You’ll now see a list of stuff that gives you information about the app, including Storage, Permissions, Memory Use, and more. These are all clickable items. You’ll want to click on Storage.
  • You should now clearly see the Clear Data and Clear Cache buttons for the application.

Problem #7: Galaxy S7 cannot save alarm after an update | Galaxy S7 slow performance issue, slow typing after installing update

I’m trying to set my alarm for the morning, and with the last update there was a giant save button that is no longer on the clock. I can’t find a way to save an alarm at all with the new update.

Also, the typing is incredibly slow. I’m currently writing this, and the keyboard doesn’t even catch up until I’m half way done with the sentence making it incredibly hard to detect errors in spelling. I really need an alarm to get up in the morning.  — Breanna

Solution: Hi Breanna. Whether you installed a security update or a major Android update like Nougat, we recommend that you do these steps to fix the problems you’re having (in this order):

  1. wipe the cache partition
  2. install app and system updates (if they are available)
  3. uninstall incompatible apps
  4. factory reset

We’ve already provided the steps on how to wipe the cache partition and factory reset above so make sure that you follow them.

The second possible solutions involve installing app or pending system updates. This will ensure that all apps are prepared to work with the current Android version running on the device. Keep in mind that installing an Android update does not necessarily mean that apps are updated as well. Outdated apps can lead to incompatibility issues which can manifest in slow performance and weird app behaviors. Make sure that you go over your list of apps and install updates that may be available in Google Play Store. We’re assuming that you don’t install apps from third party sources outside Google Play Store but if you do, it’s your responsibility to update them accordingly. How to do that depends whether a source has an available update for an app. Try to contact the developer if you aren’t sure if an app is compatible with the operating system you have.

Needless to say, you only need to install compatible apps. Bear in mind that not all apps are designed to work with all or with the latest Android versions. If you tend to install apps without checking possible compatibility issues, think again and visit the app’s Play Store page to read reviews from other users. Sometimes, developers will also indicate if their product is compatible with a particular Android version so watch out for that as well. The general rule is to ensure that you only install compatible apps.

We don’t know what alarm app you’re using so we cannot provide specific steps on how to save an alarm for you. Try doing some research on how to do that with help from Google.

Below are specific topics we’re bringing for you today:

Problem 1: Galaxy S6 edge losing People edge contact color after Nougat update

My edge contact colour gone, music player keeps stopping with error… all after the update! So disappointed. Wish i hadn’t updated. It’s like my phone is a different phone altogether. Horrible job Android…my Samsung S6 edge isn’t what it was before. All the features i loved, are gone! What is the point of the edge contacts??? No point now???? Why take it away now???? Samsung should refund us and give out new phones then if they dont want us to use the features we had on our phone…. My phone is called a Galaxy S6 Edge!!!! So unhappy! The update has ruined all my settings and taken a lot away from the features i loved. Not happy at all. — Sandra

Solution: Hi Sandra. Android as an operating system evolves. That means that it regularly receives new features while also losing some. Unfortunately, the end user like you does not control what gets added or removed come a new Android version. It all depends on the developers, which can be Samsung (or any other hardware maker), Google, or your carrier.

We are positive that Samsung removed some features in their Galaxy S6 and S7 edge phones, like the one that allows a user to assign different colors for a number of contacts in People edge. We think this feature is a handy one but Samsung did not provide any rationale why they stopped supporting it. Like you, there’s nothing much that we can do for this. We have no influence over Samsung’s or any developer’s decision to change whatever they feel is necessary.

If you want to let Samsung know of your negative experience, we suggest that you contact its customer service directly.

Problem 2: Galaxy S6 randomly calls numbers not listed in Contacts app

I just recently bought a used unlocked Verizon Samsung Galaxy S6 and my service provider is Straight Talk. The phone is in mint condition, however, it makes random calls to random people who are not in my contacts. I keep getting callbacks from people saying that they got a missed call from my phone number. I am not calling anyone. This happens often and it’s getting very frustrating. Please help! ***I’m also not sure what android version I have so I guessed. — Tammy

Solution: Hi Tammy. Do a factory reset first and observe your phone for a few days. Make sure that you don’t install anything — apps or updates — during this period. Since your phone will be running pre-installed apps only at this time, this may help your identify or narrow down possible causes. If your phone goes back to working normally during this time, it’s very likely that one of the installed third party apps is to blame. On the other hand, if the issue continues even after a factory reset and without any apps installed, you must contact your carrier and report the problem.

Below are the steps on how to factory reset your Galaxy S6:

  1. Create a backup of your important files such as photos, videos, contacts etc. You can use Smart Switch for this task.
  2. Turn off your Samsung Galaxy S6 Edge.
  3. Press and hold the Volume Up, Home and Power keys together.
  4. When the device powers on and displays ‘Power on logo’, release all keys and the Android icon will appear on the screen.
  5. Wait until the Android Recovery Screen appears after about 30 seconds.
  6. Using the Volume Down key, highlight the option, ‘wipe data/factory reset’ and press the Power key to select it.
  7. Press the Volume Down button again until the option ‘Yes — delete all user data’ is highlighted and then press the Power key to select it.
  8. After the reset is complete, highlight ‘Reboot system now’ and hit the Power key to restart the phone.

 Problem 3: Galaxy S6 fails to play video and audio files after installing Android Nougat

After updating my phone to Nougat, audio and video files failed to play. This happens on the default video ad music app as well as in Instagram, Facebook, and Youtube whenever I play video. However, the problem is fixed when I restart my phone but it doesn’t fix it permanently. The problem returns after 1 or 2 days. I already did a wipe cache partition as well as factory reset but the problem still persist. Thank you for the time for reading this and helping me. I’m really hoping that you could help me as I was desperately finding a solution for my phone. Have a nice day! — Raymond

Solution: Hi Raymond. The cause of the problem may be app-related. To check, set your phone to safe mode and see how the device works while playing a video or audio file. Safe mode blocks third party apps and services. If the issue is non-existent during this time, you can bet one of your apps is causing the problem. Here’s how to do that:

  1. Press and hold the Volume Down and Power keys for 20 to 30 seconds.
  2. Once you see the Samsung logo, release the Power key immediately but continue pressing the Volume Down key.
  3. Your phone should continue booting up and you will be prompted to unlock your phone as usual.
  4. You will know if the phone successfully booted in safe mode if the text “Safe mode” is displayed at the lower-left corner of the screen.

It’s important that you invest some time to do the observation since there’s no direct way to test if an app is causing the problem. Allow the phone to run in safe mode for a few days so you’ll see the difference.

If the phone continues to fail to load video or audio files even when on safe mode, do another round of factory reset and again observe how the phone works for a few days. Make sure that you don’t install any app or update to allow only pre-installed apps to work during this time. This will be the last troubleshooting step that you must do, and should give you an idea whether the problem can be fixed or not. If the issue remains during the observation period, have the phone replaced.

We think that your problem is caused by an app so if the phone works normally after a factory reset, be sure to install only compatible and trusted apps. Some compromised apps will initially allow you to install legit versions but would later on switch to bad versions for whatever purpose their developers may have in mind. This is the main reason why you should only install apps from trusted developers. If you tend to install apps from third party sources, don’t expect not to experience problems later on.

Problem 4: Galaxy S6 edge stuck in Sprint logo screen, apps keep freezing

Hello! I own a Samsung Galaxy S6 edge. I updated the latest software around a week ago and since then my phone freezes on apps and when I restart it freeze on the “Sprint LTE” screen in which I have to hold power and home button down to get it out of. The typing has become laggy and the charge doesn’t stay anymore either. I don’t know if it’s the new software or time for a new one considering the S8 came out. Please help! — Madisynh

Solution: Hi Madisynh. Try wiping the cache partition first. This will ensure that you have refresh the phone’s system cache. Here’s how it’s done:

  1. Turn off the device.
  2. Press and hold the following three buttons at the same time: Volume Up key, Home key, and Power key.
  3. When the phone vibrates, release the Power key but continue to press and hold the Volume Up key and the Home key.
  4. When the Android System Recovery screen appears, release the Volume Up and Home keys.
  5. Press the Volume Down key to highlight ‘wipe cache partition.’
  6. Press the Power key to select.
  7. When the wipe cache partition is complete, ‘Reboot system now’ is highlighted.
  8. Press the Power key to restart the device.

If the issue continues after wiping the cache partition, do a factory reset. We believe that any or both of these procedures should address your issues. If they won’t, that’s an indication that the firmware version may be coded poorly, or that a much deeper problem like a bad hardware exists. Either case, you’ll need to send the phone in for repair or replacement.

Problem 5: Galaxy S6 laggy and slow, camera keeps crashing, and apps become unresponsive after an update

Hi. Thank you so much for helping! The tips on the website are excellent.

I installed a new update on my Samsung S6 Edge yesterday to Android 7.0. After the update, the phone became very slow, several apps are unresponsive and shut down, the camera goes to black every few seconds and the back button doesn’t work. I performed a cache wipe based on instructions from your site. This didn’t resolve the issues, unfortunately. Is there any known resolution to these issues, or would I need to replace the phone? The hardware of the phone is in otherwise excellent condition, as it lay unused for over a year when I originally bought it, so it is as good as new. — Radha

Solution: Hi Radha. The other troubleshooting steps that you can do in this case should be to:

  1. factory reset the device
  2. and to ensure that you only install necessary and 100% compatible and official apps.

If the problem continues after doing these two steps, go ahead with a phone replacement.

Problem 6: Galaxy S6 camera won’t work after hardware repair

Just replaced the LCD and digitizer on my Galaxy S6 (due to moisture damage). All works fine with the exception of camera. A “CAL” change testing device error appears.

Also, wifi works fine. however I cannot get a connection to my carrier’s network. Tried rebooting, clearing data and cache etc. Haven’t tried a Factory Reset. Is that required after a screen replacement? Thanks. — Jim

Solution: Hi Jim. Factory reset is usually the last possible software solution an end user can try. It’s not necessary after hardware repair but if you think the problem is due to a software bug, go ahead and do it. We don’t think it will help fix your problem though. If your phone was previously exposed to water, the most likely reason for your problems is hardware malfunction and not software-related, which means you may not be able to fix them at all unless you replace the entire motherboard or the phone.

Problem 7: Galaxy S6 soft keys not working after water damage

I dropped my S6 into a water (toilet) for a 1 second and grab it and clean it immediately with towel. It wasn’t shut down and it was working, but the touchscreen is pressing one or two buttons by itself. It works and I can use it and open everything I want, but it goes back by itself. So, if I’m trying to type message on Facebook, I must write few letters then it closes Facebook app by itself. so I have to open it again and continue writing, and etc. Or when I’m in messages app, it opens settings in right up corner. So I thing that it have been pressing this two buttons in right up and right down corners. Everything else works. I try to left it in rice but it didn’t help. Thank you for your help. — Katarina

Solution: Hi Katarina. The length of time when your phone got exposed to water does not matter at all. What matters is the fact that your phone started showing problems right after the incident. The Galaxy S6 does not enjoy water resistance protection so even a fraction of a second of exposure can lead to permanent problems. Ideally, you’re supposed to turn off the phone, remove the battery, dismantle everything, clean all the parts with alcohol, and dry the phone in a bag of rice for a few days. And that’s only the “first aid,” not the “cure.” You must then have the device repaired if problems show.

We know you can’t do the “first aid” part because the phone is difficult to open. This is the reason why recommend that you let a professional check your phone now. If you’re lucky and the water damage is only isolated to the soft keys area, a repair may  bring back your device to working order.

Problem 8: Galaxy S6 won’t charge unless plugged in

Hi. I’m actually in Canada with Telus. Not T-Mobile. My phone will not connect or at least show a charge when connected to cable. Outlet, USD to PC, it doesn’t start to charge or show lightning bolt icon.

If powered off and connected, it does charge to 100% over about 8 hours. I’ve never noticed power issues. The previous day it was powered down to zero for a few hours as I didn’t have access to a charger. It charged over night in power off status, to about 65 percent. When it got down to 5% later that day I tried to charge It, and that’s when I first noticed. I’m using 2 different cables, one came with mine and one with my wife’s S8, (fast charging something which seems to be a much slower cable to charge with on either phone) both cables work for S8.

What I find the strangest is that it does charge in power off, but not at all if power is on. Any help would be appreciated. Running Android software version 7.0. — Alex

Solution: Hi Alex. There may be a lot of apps and services running actively and in the background when your phone is turned on. Go over your list of apps and uninstall the  ones you don’t need. After that, check your apps again and make sure that you only leave those that are compatible and coming from trusted developers. Remove anything that you don’t need like games. If possible, do a factory reset and observe how charging works when only pre-installed apps are there.

You also want to ensure that the operating system detects the battery level properly so make sure that you recalibrate the battery after a factory reset. Here’s how it’s done:

  1. Use the phone by playing games or doing tasks to hasten power discharge, until the phone turns itself off.
  2. Turn the phone on again and let it turn itself off.
  3. Charge the phone without turning it back on.
  4. Wait until the battery says it fully charged to 100%
  5. Unplug the charger and turn the phone on.
  6. If the phone says it’s not 100% anymore, turn it off, plug the charger back in and wait until 100% charge is reached.
  7. Unplug the charger the turn the phone on again.
  8. Use the phone until you drain the battery down to 0.
  9. Repeat the cycle once.

Problem 9: Galaxy S6 edge plus won’t charge or turn on

I have a S6 edge plus, used it for 1 and a half year. Everything was fine till yesterday. I was browsing through my phone and insert the original fast charging cable to the phone. Suddenly it just auto restart. After it restart, it hangs again. Then auto restarts. The cycle went on many times. So I just quickly did a software upgrade while it is still on. The upgrade took about 15 mins, and the phone stay on throughout. After update, the same thing happen again… hang and auto restart. After several tries, I can’t turn on the phone at all, but the blue LED light is on. Tried to power it on  after many attempts. Finally it powered on once… but went off. This time around i can’t power it on and can’t charge. Plug it into many different charger and computer , and it is still not responding , not even the red charging led light. Please help… Thanks in advance. — Dodo

Solution: Hi Dodo. Try to see if you can start the phone to alternate modes. If your phone remains unresponsive and continue not to charge, there’s really nothing much that you can do except to send it in to be repaired or replaced.

Below are the steps on how to boot your phone to alternate modes:

Boot in Recovery mode:

  1. Charge the phone for at least 30 minutes.
  2. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  3. When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  4. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  5. Using the Volume Down key, navigate through the options and highlight ‘wipe cache partition.’
  6. You can either wipe the cache partition or do a factory reset when in this mode.

Boot in Download Mode:

  1. Charge the phone for at least 30 minutes.
  2. Press and then hold the Home and Volume DOWN keys, then press and hold the Power key.
  3. When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume DOWN keys.
  4. Wait until the Download screen appears.
  5. If you can boot the phone in download mode but not in other modes, that means that your only way out may be to flash a stock or custom firmware.
  6. Use Google to look for a guide on how to do it.

Boot in safe mode:

  1. Charge the phone for at least 30 minutes.
  2. Press and hold the Power button.
  3. Once the ‘Samsung Galaxy S7’ logo appears, release the Power key and immediately press and hold the Volume Down button.
  4. Continue holding the button until the phone finishes rebooting.
  5. Once you see the text “Safe mode” at the bottom left corner of the screen, release the Volume Down button.
  6. The only difference of safe mode from normal mode is that the former prevents third party apps from running. If you can boot the phone in safe mode but not in normal mode, uninstall all apps until the issue (that prevents you from booting normally) is eliminated.

Problem 10: Galaxy S6 won’t fast charge with Anker power bank

Hi. would be curious to find an answer to this: my Samsung S6 was updated around the 2nd week in May and it has never charged up fast again, using my Anker power charger anymore, without it being a painstaking experience. Oddly, it does still charge normally using the Samsung wall charger (it takes the same fast charge time as before) but the power battery charger that worked perfectly before, (charged fast) now takes 5-6 -7 hours to fully charge. I’ve charged my wife’s iPhone 7S using the power charger and it charges just normal (as fast) as before. So I know it is the phone not the charger … and it started EXACTLY the first time i used the power charger after the update. I’ve cleared cache, charged in Safe Mode … nothing has worked to let me use the power charger. What gives?! — Francis

Solution: Hi Francis. Try a factory reset and see what happens. There may be a software glitch causing it. There’s no way to know where the problem lies but if you’re positive that the only different thing that you did was to install an Android update, we hope that a factory reset on your phone will help. Refer to the steps above on how to do it.

Galaxy Note 4 won’t charge, charging symbol comes up but then disappears again, other issues

Hello and welcome to another #GalaxyNote4 post. As usual, we’re here to discuss solutions to problems reported by some members of our community. Keep watching for more similar posts in the coming days.

If you are looking for solutions to your own #Android issue, you can contact us by using the link provided at the bottom of this page.

When describing your issue, please be as detailed as possible so we can easily pinpoint a relevant solution. If you can, kindly include the exact error messages you are getting to give us an idea where to start. If you have already tried some troubleshooting steps before emailing us, make sure to mention them so we can skip them in our answers.

Below are specific topics we’re bringing for you today:

Problem 1: Galaxy Note 4 lags when typing SMS

Texting issue. I am experiencing MAJOR lag time between typing and having letters appear. It is like the phone is freezing while I type. It is especially present when someone is in the process of texting me. For instance, if I am receiving texts I have to wait minutes before I can text back…the app freezes and many times asks me to shut it because it is “not responding.” I do not want to do anything that will erase the texts I have as I often need to refer back to many for business…please let me know if you can help. I have tried changing the battery, deleting old texts to try and free up space, and clearing the main cached data. Nothing is working. I do not want to get a new phone until the new note gets released. Everything else works fine. Also I have no idea which Android version I have so I just selected a random answer below. — Bea

Solution: Hi Bea. We don’t know for sure if by “clearing the main cached data” you’re referring to the steps below:

  1. Open the Settings menu either through your notification shade (drop-down) or through the Settings app in your app drawer.
  2. Navigate down to “Apps”. This may be renamed to something like Applications or Application Manager in OEM skinned versions of Android 6 or 7.
  3. Once in there, click on an application.
  4. You’ll now see a list of stuff that gives you information about the app, including Storage, Permissions, Memory Use, and more. These are all clickable items. You’ll want to click on Storage.
  5. You should now clearly see the Clear Data button for the application. Tap Clear Data.

If you’ve already tried the steps above before contacting us, your next move would be to check if the problem is being caused by another app. You can do that by booting your phone to safe mode. Safe mode blocks third party apps and services so if texting works fine, that’s proof that our suspicion is correct. If you haven’t tried restarting to safe mode before, here’s how:

  1. Turn off the phone completely.
  2. Press and hold the Power key and the Volume Down key.
  3. When the phone starts to boot, release the Power key but continue holding the Volume Down key until the phone finished restarting.
  4. Safe mode will be display at the lower left corner; you may release the Volume Down key now.

If both procedures won’t fix the issue at all, try using a different messaging app.

Problem 2: Galaxy Note 4 slow performance issue when typing text message or using an app

I am having a weird lagging issue. It presents itself in two ways.

1) when I am texting the system will freeze up. It will still recognize what I have typed during the freeze. At the end it will display everything but it does it looking “some something something like something like this.”

2) when I am playing a game or using an app like Slack or Google the inputs will freeze, similar to the texting issue. You can hear the music and watch the characters, bit touch inputs aren’t being displayed it is like that system is currently shut off. The amount of time varies. And I can’t recreate it so I don’t know why it is happening or if there is something in the back ground running. I wish I had more, but to ally and appreciate any help, so annoying. — Tim

Solution: Hi Tim. Your texting issue may be similar to Bea’s above so make sure to do our suggested procedures above. If the problem won’t go away at all, make sure to do a factory reset and observe the phone right after. Be sure not to re-install anything during this period. Slow performance problem like what you’re experiencing can be due to software glitch or hardware malfunction. If the phone continues to lag even without apps installed after a factory reset, you can assume bad hardware is the culprit. In this case, we strongly suggest that you get a new phone instead of having it repaired.

Problem 3: Galaxy Note 4 won’t charge, charging symbol comes up but then disappears again

Okay, so whenever I plug my Note 4 in, the charging symbol will flash momentarily, then it will disappear. It will then vibrate and flash the charging symbol again and then quit, and it repeatedly this cycle every two or so seconds. Now here’s where I’m quite confused (and frustrated). I tried the soft reset and it worked! The phone was charging and it turned on and worked without a problem. I decided that I needed to insert my SIM card (not sure how it got out). When I pulled the battery out and inserted the SIM card, the device went back to square one only this time, soft reset doesn’t work. Please, any assistance would be greatly appreciated. — Jacob

Solution: Hi Jacob. Firstly, we assume that your phone was never physically impacted or exposed to water before. Any of these two can cause serious hardware problems which can sometimes manifest in the form of the problem you’re describing here. If your phone was physically damaged before, stop wasting your time and effort asking for solutions online as they can’t help you at all. You should focus instead on having the phone repaired or replaced.

Secondly, the most that you can do in terms of software solution is try a factory reset. Doing so will revert everything back to their defaults, eliminating whatever bug  that may have developed after some time. To factory reset your Note 4, try the following:

  1. Turn off the Galaxy Note 4 completely.
  2. Press and hold the Volume Up and the Home keys together, then press and hold the Power key.
  3. When the Note 4 vibrates, release both the Home and Power keys but continue holding the Volume Up key.
  4. When the Android System Recovery shows on the screen, release the Vol Up key.
  5. Using the Volume Down key, highlight ‘wipe data / factory reset’ and press the Power key to select it.
  6. Now highlight ‘Yes — delete all user data’ using the Vol Down key and press the Power key to begin the reset.
  7. When the master reset is complete, highlight ‘Reboot system now’ and hit the Power key.
  8. The Note 4 will restart but it will be longer than usual. When it reaches the Home screen, then begin your setup.

Remember, if the problem persists bad hardware must be to blame. It can be a charging port issue, or something in the motherboard.

Problem 4: Galaxy Note 4 keeps freezing and rebooting on its own

My N910T was running great up until a couple of weeks ago and all of a sudden it started to freeze up and restart. I tried to do a factory reset, tried to clear the cache. I also Odin flashed ROM again and pit file after wiping and doing a factory reset still doing the same thing. Down loaded wake lock from play store it works normal again but would like to fix it permanently. Can I Odin flash back to 5.11 from 6.01? That’s the only other thing I can think of. Not sure if it’s possible. Any help would be great.

Oh I forgot I have held the power button in for ten seconds without the battery several times too with no luck. — Tommy

Solution: Hi Tommy. If your phone worked normally again after installing an app that prevents or minimizes wake lock, that should tell you one thing — an app or apps must be causing the problem. If a factory reset did not fix the issue, that’s probably because you simply re-installed the same set of apps afterwards.  Make sure to go over your list of apps and gradually eliminate possible causes by uninstalling and testing.

Reverting to an older firmware version would not help at all, especially if you’ll continue to re-install the cause of the problem in the first place.

Problem 5: Galaxy Note 4 lags when opening apps

I have a Note 4. After a software update on May 31st the phone has been giving me lots of troubles. It lags when trying to perform any tasks like opening apps etc. It will eventually shut off after a few minutes & I can’t turn it back on without taking the battery out. Even then it sometimes gives me a screen that says “downloading, do not remove target.” If I keep taking the battery out eventually I can get it back on but just momentarily. — Lorrie

Solution: Hi Lorrie. Try to clear the system cache first and see how it goes. Here’s how:

  1. Turn off the Galaxy Note 4 completely.
  2. Press and hold the Volume Up and the Home keys together, then press and hold the Power key.
  3. When the Note 4 vibrates, release both the Home and Power keys but continue holding the Volume Up key.
  4. When the Android System Recovery shows on the screen, release the Vol Up key.
  5. Using the Volume Down key, highlight the option ‘wipe cache partition’ and press the Power key to select it.
  6. When the wiping of the cache partition is finished, highlight ‘Reboot system now’ and hit the power key.

Should nothing change, that’s the time that you want to consider doing a factory reset.

Sometimes, factory reset won’t have the effect that you’ll expect because you’re not actually addressing the real issue. For an issue like yours, there’s a fair chance that one of your apps is problematic so you want to make sure that you observe how your phone works without any apps at all. That should give you a benchmark regarding your phone’s performance.

Problem 6: Galaxy Note 4 won’t charge

Hi. So when I plug my charger in it beeps on and off as if I’m plugging in and unplugging the charger lead. I tried the lead to my PC which worked fine for almost a day. Then it flashed up the device had malfunctioned and no longer charges. At wits end I tried other leads / chargers to no avail. Cleaned out the port got a load of crap out of it, then plugged it into my laptop as a last ditch effort and it charged fine. But that too is now charging intermittently. Is my phone on its way out? It is only a year old. — Graham

Solution: Hi Graham. The fact that it won’t charge using a known working charger is not a good sign. If the usual set of software solutions like cache partition wipe and factory reset won’t help solve the problem, you should send it in.

Problem 7: Galaxy Note 4 won’t power back on

Dear Droid Guy. Today I checked my phone after work, the battery was 43% and I put it back in my Pocket. Everything was normal. After a couple of minutes I checked it again and it didn’t turn on. The screen was completely black and it didn’t vibrate or do anything. When I was home I tried to remove the battery and turn it on again. nothing happened. Even when I plugged it in it even didn’t vibrate or lighten up to Show that it charges. I also tried to press the power button without the battery and reinsert it afterwards. Nothing happened. I had the same problem half a year ago.. luckily the phone still had guarantee then and they replaced it with a totally new one. They said the problem came from water in the phone but the new one never touched any water. I hope you can give me an advice for saving my phone.. Thanks a lot for your time! — Lenaf2

Solution: Hi Lenaf2. There are only two things that you can do right now:

  • check if your phone still boots to alternate modes, and
  • get a new battery.

If both won’t make the phone turn back on, you’ll need to have it repaired or replaced.

For reference, below are the steps on how to start your Note 4 to alternate boot modes:

Boot in Recovery mode:

  1. Charge the phone for at least 30 minutes.
  2. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  3. When the Samsung Galaxy logo shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  4. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  5. Using the Volume Down key, navigate through the options and highlight ‘wipe cache partition.’
  6. You can either wipe the cache partition or do a factory reset when in this mode.

Boot in Download Mode:

  1. Charge the phone for at least 30 minutes.
  2. Press and then hold the Home and Volume DOWN keys, then press and hold the Power key.
  3. When the Samsung Galaxy logo shows on the screen, release the Power key but continue holding the Home and Volume DOWN keys.
  4. Wait until the Download screen appears.
  5. If you can boot the phone in download mode but not in other modes, that means that your only way out may be to flash a stock or custom firmware.
  6. Use Google to look for a guide on how to do it.

Boot in safe mode:

  1. Charge the phone for at least 30 minutes.
  2. Press and hold the Power button.
  3. Once the Samsung Galaxy logo appears, release the Power key and immediately press and hold the Volume Down button.
  4. Continue holding the button until the phone finishes rebooting.
  5. Once you see the text “Safe mode” at the bottom left corner of the screen, release the Volume Down button.
  6. The only difference of safe mode from normal mode is that the former prevents third party apps from running. If you can boot the phone in safe mode but not in normal mode, uninstall all apps until the issue (that prevents you from booting normally) is eliminated.

Problem 8: Galaxy Note 4 can’t make a call after a factory reset

Hi – hoping you can help me! Just today I have tried to set up a completely unused and unlocked Samsung Galaxy Note 4. (The history, just in case relevant, is that I had a Samsung Galaxy S3 for many years, but managed to smash it yesterday. Fortunately I had a new, boxed, Samsung Galaxy Note 4, which I’d actually obtained a few years ago as a replacement, but then I ended up happy with my S3 and it did very well, so I never actually changed, and there it sat in its box).

Anyway, having broken my S3 I thought I would get out the Note 4 and use it instead. There were no problems setting up as such. However, when I tried to transfer things from my S3 I was only able to transfer my contacts and texts before the Note 4 claimed it had no space left. Needless to say I have several apps on the S3, having had it for a few years, plus photos and a few videos – plus my contacts, texts etc. All this fitted perfectly fine on my S3. But I’d barely transferred any of it before the Note 4 claimed it couldn’t fit any more on. I did check the storage usage and it really said that out of the 16 GB, essentially all of it was used. However, when I looked at the detailed breakdown of e.g. the app sizes (all of which were pre-installed, I hadn’t yet put any new ones on), they were not very big at all.

After looking at various websites to help (most of which weren’t helpful since the assumption in all of them was that people had being storing things on their phone and should try and clear the worst of it – but of course I’d not had time to store anything yet!), I decided to do a fatory reboot. So, I did that… Whereupon.. it did *help* with the storage issue (still a bit weird… there was still a bit more than 8GB inexplicably used, maybe just due to the operating system(?), but at least that gave me more than 7GB). So I was encouraged. And started putting my contacts back on etc. *However*… now I find that I can no longer make texts or calls. (I should mention that before I did the factory reset, I didn’t test any texts but I *did* make a couple of calls, so I know it did work with the same sim card, before that).

Now, when I make a call, it cuts me off immediately, without evening ringing. And a text gets a little ‘T-mobile’ icon come up on the text, and then it fails. (I am with EE, incidentally). Does this mean the phone is somehow now locked to T-Mobile? By virtue of the factory reset? Is that why it will no longer work? (Perhaps I should mention that I did not take out my SIM card when I did the factory reset, and maybe I should have? 🙁

On the other hand, I have put it back in my old S3 and it still works fine. The S3 still does actually work, it’s just all smashed up – so I was able to test that the SIM still works with it, and it does).

Another much smaller issue, but I’ll mention it anyway, as just more info on things I’ve noticed since the factory reset, is that now when I turn the Note 4 phone on, I no longer get the Samsung logo, but just an ‘Android’ icon come up instead. Any help would be greatly appreciated. Thanks so much. — Claire

Solution: Hi Claire. Factory reset, as the name suggests, will bring all software settings back to their defaults. This means that whatever changes or modifications that were implemented temporarily in the system before will be removed as everything will be returned to their original state. We don’t know much about your system but if this is the only different thing that you did, factory reset must be the reason for the network issue you’re having. We suggest that you contact your current carrier so they can walk you through in changing the network settings. Doing so will not guarantee that your Note 4 will work again but this is actually the only thing that you can try at this time.

As we’ve said, we don’t know much about your system so we can’t say for certain is also the reason why your second issue is happening. Normally, you should get the Samsung logo first before the carrier’s splash screen appears. If that’s not happening anymore, that factory reset you did must have changed some things in the system.

Problem 9: Galaxy Note 4 keeps losing mobile data connection

Hi. I’ve been looking for a fix for my problem but couldn’t find one so i decided to ask you guys for help.

okay so i bought a Galaxy Note 4 two years ago with closed eyes and just because of big screen and the S Pen feature and didn’t think of researching about it and had 2 years of enjoy with it. But several months ago, the 4G network finally got working in my country and i was so hyped to use it! After getting my SIM card changed into a Usim card, i noticed that i can’t regularly change network mode to LTE (there are only wcdma, gsm , and auto connect gsm/wcdma options). After lots of searching, i’ve found the 4636 secret menu (which i couldn’t reach through the calling screen because nothing happened when i typed the full code into the dialing screen.

So i’ve downloaded this app named shortcut master lite to enter that secret menu . And YES i have rooted my device long long ago). Now i am able to change the network mode into LTE with the 4636 secret menu. Then i started using 4G internet connection and it was wonderfully better than 3G.

But later that day, i noticed that no one can call me and i can’t call anyone too! I’ve searched a lot in the Google and found out that my ROM (it’s the factory-installed 4.4.2 ROM and i did not install any custom ROMs or upgrades on this phone) doesn’t support voice over LTE (simply voLTE)! Okay, keeping all these problems on a side , another problem has popped out recently!

In some random periods of time in a day, my phone networks get weird! Some times LTE gives no signal, sometimes WCDMA has signal to call or SMS but the internet connection (H/H+) won’t show up, and sometimes both happen at the same time! This things are really really annoying me as hell! Please help me out if you have any idea about these 3 problems.

Notice: some says it may get fixed by unrooting and updating my android rom but i really need Root access and don’t want to lose it . But if it’s the last way , well , i will have to unRoot my phone 🙁

And another question that i had: can i actually use apps like shortcut master (which needs Root access) on 5.0+ versions of Androids without rooting? Or can i even root them? Any help from you will be hardly appreciated . — Mohammad

Solution: Hi Mohammad. The best support team that can help with your difficulty in maintaining mobile data and other network-related functions is your carrier’s technical support team. The most that you can do as regards device troubleshooting is factory reset and probably flashing to a different stock ROM. Other than these two, we can’t help you isolate what’s causing these network issues.

For your question regarding the possibility of using Shortcut Master with Android Lollipop, we recommend that you contact the app’s developer. We’re not familiar with this product and we haven’t used it ourselves. Talk to its developer to get first hand information.

Problem 10: Galaxy Note 4 wifi won’t turn on

Hi, I have a Samsung Galaxy Note 4 and for a while (maybe 2 months or more) I have had an issue where the wifi is very slow to turn on. I have mostly just avoided turning it off at all, however yesterday my battery died and once I got it on charge and turned the phone on the wifi would just not turn on at all. It has been 16 hours now and it just refuses to turn on. What I mean is, I pull down the slide down menu and click on the wifi button to switch on, it greys out and then just stays that way.

I have also tried turning it on using the toggle button in the settings menu but it does the same thing-greys out and never switches on. While it is greyed out I also cant toggle it back to the off setting. I have tried many fixes online- turning phone off and taking battery out for 2 minutes, taking battery out while phone is still on, toggling airplane mode off and on, lightly tapping the back of phone in case of loose wiring, turning power saving mode off, turning wifi power saving mode off, clearing RAM, deleting unused apps. Nothing works. The only thing i have not tried is factory reset as I can not back up my data unless I can connect to wifi, so I do not want to do this. I do not have access to a computer as I am travelling and only have my phone and a Samsung tablet. Please help! — Rachelle

Solution: Hi Rachelle. Have you tried checking if a third party app is responsible for this glitch? If your answer is no, boot the phone to safe mode (steps provided above) and see.

If wifi remains problematic after that, we’re afraid you have no other choice but a factory reset.

Bad wifi rarely happens but sometimes, a hardware issue like a damaged networking chip can also cause wifi to fail. If factory reset won’t fix the issue either, get a new phone.

Problem 1: Galaxy Note 4 shuts down on its own even there’s enough battery | Galaxy Note 4 keeps showing Android download page

Hey, my Samsung Note 4 has been shutting off by itself even when it’s got battery life. I would have to take the battery , wait for a few minutes and put it back in then turn it on with it on charge. This is the only way of it turning on. It would not turn on with out the charger even though it would have battery life.

Also when it does turn off by itself it shows some sort of Android download, while I’ve tried to download but it would take days. What do I do ? And what is wrong with it ? Please help. —         Garciannes

Solution: Hi Garciannes. For your first issue, the cause is most probably the battery itself. If you have  been using your Note 4 for at least 2 years now, the battery may have simply lost the ability to hold a charge. In other words, it may not be working like it was before. This is normal, especially as a Lithium-based battery like the only in your phone gets older. We recommend that you try to recalibrate the battery first and see if it fixes the problem. If it doesn’t, go ahead and get a new battery.

Below are the steps on how to recalibrate the battery:

  1. Use the phone by playing games or doing tasks to hasten power discharge, until the phone turns itself off.
  2. Turn the phone on again and let it turn itself off.
  3. Charge the phone without turning it back on.
  4. Wait until the battery says it fully charged to 100%
  5. Unplug the charger and turn the phone on.
  6. If the phone says it’s not 100% anymore, turn it off, plug the charger back in and wait until 100% charge is reached.
  7. Unplug the charger the turn the phone on again.
  8. Use the phone until you drain the battery down to 0.
  9. Repeat the cycle once.

For the second issue, it’s cause can vary a lot. In some cases, it can be due to a software glitch, while in others, it can due to an unknown hardware bug. We suggest that you do a factory reset and see how it goes from there. If the problem remains after a factory reset, you can assume bad hardware is to blame. In this case, you should consider getting a phone replacement.

Below are the steps on how to factory reset your Note 4:

  1. Turn off the Galaxy Note 4 completely.
  2. Press and hold the Volume Up and the Home keys together, then press and hold the Power key.
  3. When the Note 4 vibrates, release both the Home and Power keys but continue holding the Volume Up key.
  4. When the Android System Recovery shows on the screen, release the Volume Up key.
  5. Using the Volume Down key, highlight ‘wipe data / factory reset’ and press the Power key to select it.
  6. Now highlight ‘Yes — delete all user data’ using the Volume Down key and press the Power key to begin the reset.
  7. When the master reset is complete, highlight ‘Reboot system now’ and hit the Power key.
  8. The Note 4 will restart but it will be longer than usual. When it reaches the Home screen, then begin your setup.

Problem 2: Galaxy Note 4 keeps freezing, won’t turn on

Sprint Note 4 SM-N910P Power On Issue Matt Rankin to mailbag 13 minutes ago. Details: I have followed your troubleshooting guide to a T for devices that won’t turn on. Only occasionally doing a soft reset allows my phone to come on. Once it is on it freezes a lot and sometimes randomly reboots to the bootloader. Then I power it off and soft reset it 15 to 20 times and if I’m lucky it will turn on again. Do you recommend I just replace the circuit board with one like this (https://www.ebay.com/itm/282417084613)?

Like the note 4 because of the IR blaster for controlling devices like tvs and dvd players and I want to get by on the note 4 until the note 8 comes out this fall. I do a lot of LCD/digitizer repairs for friends and I have decent soldering skills so if there is minor soldering I can do to repair my current motherboard I would be blabergasted. Let me know what you think with your experience. Thanks. — Matt

Solution: Hi Matt. We don’t usually recommend motherboard repair because there’s a long list of possible problems that can happen out of it. With motherboard replacement, you have to ensure that the board and all components in it are working fine, something that can be done quite easily. In fact, it can be very challenging even for a Samsung technician who’s equipped with complete tools to do the checking.

We cannot also confirm if the motherboard listed in that eBay link will work with your device. If you read the “Item specifics” at the bottom part of that page, it says this board is pre-owned, which means that it may be defective, or problematic. There’s no system in place to check if such board is working fully at this time but if you want to accept risk, go ahead and see for yourself.

Problem 3: Galaxy Note 4 randomly reboots, not turning on

I am having serious problems with my Note 4 device. My Note 4 turns off randomly and will not come on until battery is removed. Sometimes I will have to wait 5 mins before phone comes back on and lately it took 2 days to restart. I am constantly having to take battery out and push the power button until it comes back on. I tried to update it and it shut down as well. I bought a new battery and still doing the same thing. I tried the restart button and phone will not come back on. If you can help it will be greatly appreciated. Thanks in advance. — Will

Solution: Hi Will. Random reboot issue can be caused by a number of factors. The cause can be one of the following:

  • a software glitch
  • a problematic app
  • malware
  • malfunctioning battery
  • bad Power button
  • unknown hardware error

The first three items (software glitch, app, or malware) can be fixed by doing a factory reset. If you’ve never tried a factory reset at this time, we strongly suggest that you do it now so you can observe the phone. Make sure not to install apps and updates right after a factory reset so you’ll know if the problem is being caused by an app or not. Should the issue remain after a factory reset, you should start to consider sending the phone in for repair or replacement.

Problem 4: Galaxy Note 4 can’t make voice calls, can’t send and receive SMS

Hi. I’m hoping you can help me. I have had my Note 4 phone for several months now. it is unlocked from Verizon. After fixing some settings I was able to make it work with my T-Mobile family account and have had no problems for months until the other day. When I try to make a phone call I get a recording saying “you are unable to complete this call at this time” and hangs up. When I try to text I get “Free Message: Unable to send message – Message Blocking is active.”

My boyfriend and I are both on the same account and he originally had the same issue. However, they were able to fix his problem but because my phone is unlocked well you already know the answer to that. When it first started I was able to have internet just wasn’t able to make or receive calls or texts but now my data doesn’t work at all. I compared my network settings with my boyfriend’s phone and the only difference is that we showed was under Network Mode his was set to WCDMA however my phone does not have that option. The only options I have are: LTE/GSM/UMTS, LTE/CDMA, OR GLOBAL. I hope you can help thank you for you time. — Jessiqn75

Solution: Hi Jessiqn75. T-Mobile network uses GSM technology so any device registered on this network should show GSM or similar. Making your device work with a particular carrier requires more than just changing the network types. We don’t know the status of your device’s software so there’s nothing much that we can tell you where the problem may lie. If you recently changed some settings or installed something before noticing the problem, try to undo them to see if that will make any difference.

For more in-depth troubleshooting, you should work with your carrier’s technical support team in order to know if the issue lies on their end, or if there’s something that needs to be reconfigured in your phone.

Problem 5: Galaxy Note 4 won’t charge, won’t turn on

I had this Note 4 since it came out but last year it has broken down. It used to show the green Android guy when i power on but after leaving it unattended for about 8months when charging, its only able to show the red charging light by the side and the green battery percentage in the middle. It’s unable to turn on to display anything more. It is perhaps due to not using it for a long period of time. — Phoebe

Solution: Hi Phoebe. If the phone no longer turns on at this time, the only troubleshooting that you can do at this time is to replace the old battery with a new one. Doing so will let you know if the issue is battery-related, or if it’s something in the phone itself.

Since the device still indicates that it recognizes the charger (due to red LED), there’s a chance that you may be able to revive the phone by starting it to different boot modes. Below are the steps on what you need to do:

Boot in Recovery mode:

  1. Charge the phone for at least 30 minutes.
  2. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  3. When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  4. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  5. Using the Volume Down key, navigate through the options and highlight ‘wipe cache partition.’
  6. You can either wipe the cache partition or do a factory reset when in this mode.

Boot in Download Mode:

  1. Charge the phone for at least 30 minutes.
  2. Press and then hold the Home and Volume DOWN keys, then press and hold the Power key.
  3. When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume DOWN keys.
  4. Wait until the Download screen appears.
  5. If you can boot the phone in download mode but not in other modes, that means that your only way out may be to flash a stock or custom firmware.
  6. Use Google to look for a guide on how to do it.

Boot in safe mode:

  1. Charge the phone for at least 30 minutes.
  2. Press and hold the Power button.
  3. Once the ‘Samsung Galaxy S7’ logo appears, release the Power key and immediately press and hold the Volume Down button.
  4. Continue holding the button until the phone finishes rebooting.
  5. Once you see the text “Safe mode” at the bottom left corner of the screen, release the Volume Down button.
  6. The only difference of safe mode from normal mode is that the former prevents third party apps from running. If you can boot the phone in safe mode but not in normal mode, uninstall all apps until the issue (that prevents you from booting normally) is eliminated.

Problem 6: Galaxy Note 4 won’t charge sometimes

I cannot charge my phone from the wall ports at all times however this is possible sometimes. although this is not caused by the charger cord because I’ve tried my charger in other phones and it works perfectly however, my Note 4 will only charge at specific times and if I unplug the charger while it’s charging and then try to plug in the charger again, it won’t work. I’ve tried to charge using a computer and it does work (sometimes again). When I connect the charger after switching my phone off it does show the charging indication and it fades away and doesn’t show the charging led orange light. I have already tried factory resetting my phone and also cleaning the charging port. I’ve read that the problem is with the firmware rather than the hardware. my android version is 6.0.1 and I’ve also read that downgrading the software would bring this a fix, if so can you tell me how to downgrade my phone. if no can u suggest a fix? — Husham

Solution: Hi Husham. We don’t know where you get the idea that it’s a firmware issue but it looks like a hardware malfunction to us. Inconsistency while charging is almost always due to either a charging port issue or a motherboard error. If the problem is firmware-related, your phone’s charging behavior should change after you did a factory reset. For this reason, we suggest that you consider getting your phone’s hardware checked so a technician can assess the status of the hardware, especially the charging port.

Problem 7: Galaxy Note 4 slow performance issue, apps keep crashing

I connected my Galaxy Note 4 to my computer to upload pics. The next day the phone said my SD card was corrupt, and all of my pics were gone. When I explore my files the files show they are there but empty. Took it to AT&T, they formatted the card and then told me all data was lost. I downloaded a recovery app and most of the pics came back, but only certain ones were recovered. pics I had in texts also show up and pics that were long deleted. Everything was fine, working fine. But now my phone is slow, freezes, programs stop running for no reason. When I try to text and choose from contacts it always freezes. My keyboard is slow, and freezes. I’m ready to break this thing! I’ve lost pics, and documents, content disappears from my phone. I’ve tried restarting, removing battery and restart, updated all app and phone software. I’m afraid to save anything to the SD card in case it becomes corrupt again. Any advice or insight would be greatly appreciated. — Jabeiler311

Solution: Hi Jabeiler311. Smartphones, especially relatively older ones, can start showing their age after some time. Keep in mind that smartphones nowadays can become problematic when they start to hit the 2-year mark. Constant usage day in and day out for years can wear the hardware as well as make the software slow down. Together, they can manifest in issues many smartphone users have come to encounter like freezing, random reboots, and severe performance issues. Giving you more detailed, in-depth explanation is beyond the scope of this article but you should accept the fact that older smartphones are more prone to errors than newer ones. We know that’s not really ideal for those who wants to continue using their devices for a few more years but that’s just how things are right now. If your Note 4 has been around (at least two years), it’s possible that the reason for your problem is simply a natural by-product of device aging. To minimize the side effects of wear and tear, consider

  1. doing a factory reset first, then
  2. uninstalling unnecessary apps.

Remember, the more apps are installed, the higher the chance of app-related issues to develop. Try to stick with official apps only and keep app number to a minimum. If that won’t remedy the situation (and trust us, your phone starts to degrade the moment it left the factory), consider getting a replacement.

Problem 8: Galaxy Note 4 can’t make calls or send SMS, | Galaxy Note 4 shuts down when turning on mobile data

Hi. I recently started having problems with my Samsung Galaxy Note 4 SM-N910G. I am unable to send messages (at times it may take a long time to be sent), cannot make calls and whenever I switch on my data, I can’t use it. The Internet says that I’m not connected to any network and most of the time, my phone will switch off once I on the data. Even though the battery level is high (80%+), the phone screen blacks out suddenly and I can’t switch it back on. I will need to take out the battery for a few minutes and then place it back in, before the phone can be on again. This happened several times a day and mostly when I switch on my data. Sometimes I can send messages and make calls, but most of the time I can’t. I’ve already went to the Samsung service counter to ask for help, but the staff was unable to aid me and tell me what the problem was. She merely told me that it may be a software problem and suggested that I repair my phone by resetting it. I did factory reset and restarted my phone, but when I switch on the data again, the phone blacked out. I think it may be a hardware problem and based on the staff, I had to repair it for $587 plus service fees of $30. I’m not sure what to do as I don’t know what the root cause is. Could you help me? — Gian

Solution: Hi Gian. The first thing that you want to do is to ensure that battery has nothing to do with the problem. Try to use another known, working Note 4 battery and replicate the problem. If the issue won’t occur with a new battery, simply replace the old one.

Should the issue remains even with a new Note 4 battery, it’s possible that a more serious hardware issue is causing the trouble. Since you’ve already tried a factory reset before you contacted us, it’s pretty safe to assume that this is not due to a software bug, which also means that it must be hardware related. Since there’s no way for an end user like you to know how to fix a hardware problem, we suggest that you get the phone replaced. Keep in mind that we’re talking about the issue here wherein your phone shuts off by itself if you try to switch mobile data on.

For your voice calls and SMS issues, we recommend that you work with your carrier’s technical support to identify their cause.

Problem 9: Galaxy Note 4 won’t charge properly

Sir / madam. I have a Samsung Note 4. The problem is when I’m charging my phone, if I charge it, it is doing just fine, but if i take out the charger from my phone and put it back again immediately then it won’t charge anymore. That’s why when I plug the charger in one place, I won’t dare transfer it to another place until it’s fully charged otherwise it will stop charging.

The phone will only charge again if I do it again for another hour or more, weird right?

I checked my charger and it’s fine and does the job. So is my battery, I just replaced it with a new one. I tried cleaning the charger pin with an air hose but still the problem persist. Please advise me on what to do. —  Apollo

Solution: Hi Apollo.

As mentioned above, a lot of erratic charging behaviors are often caused by bad hardware. To check if that’s the case, consider doing a factory reset first so you can compare how the phone works afterwards. If the problem stays, then it’s either a charging port issue, or some other hardware malfunction. In either case, you want to have the phone repaired or replaced.

Problem 10: Galaxy Note 4 battery issue, freezing, blacks screen, random reboot issues

Started three days ago. Phone kept freezing up, going to black screen, shutting off on its own, etc. I had to reset the phone twice, then factory reset the phone. Received message with the green Android character saying couldn’t do normal boot; mmc_read failed; Odin mode high speed. This has happened to me several times, never had a problem with the phone before this. I’m concerned. I did what your last article said to do. Take out battery for 10 seconds and put it back in. Seems to be ok right now. But still concerned. Please help me if you can. Thank you. — Monet

Solution: Hi Monet. Looks like you can get help from using a new battery here. The symptoms you mention (freezing, black screen, random reboots) are some of the telltale signs of a dying battery. Make sure to replace the old battery you have and see how it goes. If nothing will change, the problem may be phone-related. In that case, we’re afraid you’ll want to simply get a new one.

Below are specific topics we’re bringing for you today:

Problem 1: Galaxy Note 4 can’t read 512GB SD card

Can a Samsung Note 4 use a 512GB SD card? I have been trying to transfer several hundred MP3 files to a 512GB SD card. When I format the card with Windows 7 and transfer the MP3 files to it, the computer reads them just fine. When I mount the SD card in the Samsung Galaxy Note 4, it does not show the files and announces that the card needs to be formatted. It does not give me any choices regarding type of format. I suspect the Windows 7 format will work with the Android phone. Is the correct? Can a Samsung Galaxy Note 4 android phone address a 512 gb SD card? — Phillip

Solution: Hi Phillip. A Galaxy Note 4 can only work with a microSD of up to 256GB. Even a Galaxy S8, the latest Samsung flagship, can only read a 256SD card so you’re out of luck. You can keep the card though for more advanced devices in the near future.

Problem 2: Galaxy Note 4 keeps rebooting, volume increases on its own

My phone just one day it wanted to keep turning itself down. And my Bluetooth decided it didn’t want to work either. I have a bluetooth device in my car, and doesn’t work. I tried putting my phone in safe mode, but the problem still occurs. I cannot seem to figure out the problem. I could be using my phone with all volume systems turned all the way up, and then no sound, then it will gradually turn back up.. please send help. It does it while using Spotify and Facebook. — Destiny.n.osborne

Solution: Hi Destiny.n.osborne. The most that you can do when it comes to your issues is to factory reset your Note 4. There may be an app or operating system bug that cause the said problems. If you haven’t tried doing it before, here are the steps:

  1. Create a backup of your important files such as photos, videos, contacts etc. You can use Smart Switch for this task.
  2. Turn off the Galaxy Note 4 completely.
  3. Press and hold the Volume Up and the Home keys together, then press and hold the Power key.
  4. When the Note 4 vibrates, release both the Home and Power keys but continue holding the Volume Up key.
  5. When the Android System Recovery shows on the screen, release the Vol Up key.
  6. Using the Volume Down key, highlight ‘wipe data / factory reset’ and press the Power key to select it.
  7. Now highlight ‘Yes — delete all user data’ using the Vol Down key and press the Power key to begin the reset.
  8. When the master reset is complete, highlight ‘Reboot system now’ and hit the Power key.
  9. The Note 4 will restart but it will be longer than usual. When it reaches the Home screen, then begin your setup.
  10. Check how Bluetooth and volume work afterwards. Make sure not to install any app during this time. If both problems stay, it’s time to send the phone in for repair or replacement.

Problem 3: Galaxy Note 4 becomes very slow, keeps getting TouchWiz has stopped responding error

This morning phone was slow to respond. Finally got message that TouchWiz stopped responding. Phone spontaneously rebooted a few times but would not wake up after lockscreen engaged and display turned off UNLESS I connected it to the car charger. I intentionally powered off. Powered up. It powered itself back off. I found directions for soft reset. Removed battery, held power button for a minute. rebooted. It went through an obvious reset cycle and came to a no-frills black screen with options, including reboot. Chose that using power button. All seemed well until it shut itself off. Now what? I’m unsure of the Android version – it should be on whatever the latest and greatest AT& T has rolled out to me. — Amelia

Solution: Hi Amelia. The first troubleshooting step that you need to do is to clear the cache partition. This is to force the phone to delete the current system cache and replace it with a new one. A corrupted cache can sometimes cause issues so it’s good if you can eliminate it from your list of possible causes. Here’s how to do that:

  1. Turn off the Galaxy Note 4 completely.
  2. Press and hold the Volume Up and the Home keys together, then press and hold the Power key.
  3. When the Note 4 vibrates, release both the Home and Power keys but continue holding the Volume Up key.
  4. When the Android System Recovery shows on the screen, release the Vol Up key.
  5. Using the Volume Down key, highlight the option ‘wipe cache partition’ and press the Power key to select it.
  6. When the wiping of the cache partition is finished, highlight ‘Reboot system now’ and hit the power key.

If clearing the cache partition won’t fix the problem, then your next move is to wipe the phone clean with factory reset. Steps are provided above.

There were a few cases in the past where some users were able to fix a problem similar to yours by installing a third party app to minimize wake locks. If the problem remains even after a factory reset, try to use Wake Lock by Darken from Google Play Store.

Problem 4: Galaxy Note 4 won’t boot past Odin mode, stuck in Download mode

Phone keep saying downloading do not remove from target and it also says no command at times. What do I do to fix my phone? I tried factory reset, but when I apply it nothing happens, but the phone turn off completely and I have to take the battery out to restart it every time. and when it do come up the Android guy be on its back and come up to system recovery at times. and I press reboot system, but things are still there same. — Pgrisby36

Solution: Hi Pgrisby36. If nothing happens when you attempt a factory reset, you should try to flash the bootloader. This is a logical next step since your phone appears to boot only to Odin or Download mode. Flashing requires a few things including a computer and an Odin program for the PC. Make sure that you do more research on how to do it. Below are the sample steps on how to flash a bootloader. Exact steps may vary so find a good guide for instructions. The steps below are for demonstration purposes only:

  1. Look for the correct firmware for your phone model and download it. Make sure that you select the right one. It should be the same exact firmware that ran previously on your device. We assume that you list down the firmware version somewhere. If you did not take note of it before, there’s a chance that you may pick the wrong one. As you may know now, using an incorrect firmware can cause complications so good luck with that.
  2. Let’s now say that you have identified the correct firmware. You then want to download it to your computer. The firmware file should have a bunch of files in it like AP_, BL_, CSC_, etc.
  3. Look for the file that starts with a label BL; this should be the corresponding bootloader file for this firmware. Once you’ve identified the bootloader file, copy it to your computer’s desktop or to any other folder that you can easily access.
  4. Proceed with the rest of the flashing procedure using the Odin program.
  5. In Odin, click on the BL tab and make sure to use the bootloader file you’ve identified earlier.
  6. Now, make sure that the “Device Added” status and its “ID:COM box” has turned blue before hitting the START button. This will initiate the flashing of your phone’s bootloader.
  7. Restart the phone once the procedure is finished.

Problem 5: Galaxy Note 4 has no sound, Youtube won’t play

Hello. I have a SFR Samsung Note 4. It has been causing problems since last year, and I tried everything — reset to factory, the hard reset, bought a new battery, nothing works. Same issue. No sound, don’t know why. Youtube is not loading at all. if you browse the internet, it works to an extent then it freezes and goes black. You can’t make phone calls, it delays in calling, or if I get an incoming call, the screen appears with almost 2 min delay, and once it appears it won’t let me take the call, like literally swipe the green call sign. What else can I do?

I don’t know how to use Odin and install a new operating system on it, but I think this won’t do the job either. Once I had a hard reset of it, it asked for an update, but without or with the update version, still same issues. Can you help me? — Wlf.david

Solution: Hi Wlf.david. Your phone appears to have a general software or hardware issue. We don’t know anything about your device or its history so there’s nothing much that we tell you. Please refer to our suggestions for Amelia above. If nothing will change after doing all of them (cache partition wipe, factory reset, and installation of Wake Lock app), it’s probably high time to replace the device.

Problem 6: Galaxy Note 4 shuts down when taking a picture, overheats when using flash light app, battery doesn’t charge to 100%

Hey there. I’m all the way from Guyana South America and I’m having a few problems with my phone, Note 4. I bought it second hand “refurbished.” The problems are listed below:

 

  • The phone doesn’t charge to 100% unless I clear the cache, it usually charges to around 50-70%. Also, I do use an original Samsung fast charger
  • Whenever I use the camera, sometimes to take one or a few pictures the phone shuts down. Also when I play real moto it shuts down.
  • If the phone battery reaches around 15% it shuts down and when I put it to charge it show 0%
  • when I use a flash light it gets extremely hot. I have already replaced the battery, wiped cache partition several times and did one factory reset. I have downloaded a few other apps including CM security which I don’t really trust. — Abdel

 

Solution: Hi Abdel. The only software troubleshooting that we will suggest for you is battery recalibration. If that won’t fix the issue either, there must be a deeper issue with the hardware that causes all these problems. All four issues appear related and can have a single cause. If a battery recalibration can’t fix it, you must have the phone repaired or replaced.

Here are the steps on how to recalibrate the battery:

  1. Use the phone by playing games or doing tasks to hasten power discharge, until the phone turns itself off.
  2. Turn the phone on again and let it turn itself off.
  3. Charge the phone without turning it back on.
  4. Wait until the battery says it fully charged to 100%
  5. Unplug the charger and turn the phone on.
  6. If the phone says it’s not 100% anymore, turn it off, plug the charger back in and wait until 100% charge is reached.
  7. Unplug the charger the turn the phone on again.
  8. Use the phone until you drain the battery down to 0.
  9. Repeat the cycle once.

Problem 7: Galaxy Note 4 keeps restarting on its own

I have the Samsung Galaxy Note 4 and I’ve gone the few 4 replacements going on the 5th after only having it 2 days with the same problems with all of them. It’s driving me crazy. My phone turns on and off on a daily basis even with a full battery. It will not completely turn on at times. I have tried to reset it multiple times and have taken out the battery to try to get it turn back on. I have also bought a brand new battery and it didn’t help the problem. Any idea how I can fix this problem? I have also updated the phone when they become available. — Munozcbn_1983

Solution: Hi Munozcbn_1983. It’s very unlikely that the same exact problem can occur on at least 4 phones unless you yourself is causing it. The main reason may be due to a bad app that you install after setting up your phone. To check, try to boot the phone to safe mode and observe. Safe mode blocks third party apps and services so if the issue won’t occur while safe mode is enabled, that’s a confirmation of our hunch. Here are the steps on how to restart the phone to safe mode:

  1. Turn off the phone completely.
  2. Press and hold the Power key and the Volume Down key.
  3. When the phone starts to boot, release the Power key but continue holding the Volume Down key until the phone finished restarting.
  4. Safe mode will be display at the lower left corner; you may release the Volume Down key now.
  5. Observe the phone for at least 24 hours.

You can also try to factory reset your device and observe how it works when there are no third party apps installed. Like in safe mode, you must observe the phone for a minimum of 24 hours to see a difference. If the issue is absent, uninstall apps one by one until you identify the culprit.

Problem 8: Galaxy Note 4 keeps restarting after Android 6 update

Hello. I had received an Android 6.0.1 update after which phone started restarting abruptly. Contacted Samsung service center who concluded that motherboard is faulty. But when i asked them to explain how can an update destroy the hardware, they had the only answer that, if they can’t re-flash the Android then it should be concluded as motherboard issue, as they are trained to tell that.

I took the phone back and did a research on Google and found that this problem is profound everywhere in the world and one gentleman had suggested a solution for this. The solution from him was to install an app called as Wakelock and set it to some mode. To my surprise, that worked 100% and phone was back to normal when operating in active condition. But if i try to restart it, the app would be inactive thus until i struggle and switch on the phone and reset the app to the above said mode, the phone doesn’t work properly.

Meanwhile, when i spoke to Samsung customer care, they said that they have released a new update, which solves this issue. So i waited for the update and finally i got this new update and i tried to install it. As soon as i gave install, phone went into boot mode and then it never recovered after that. the phone is dead now. Completely dead. tried all the basic steps, like soft start, safe mode, recovery mode. nothing is working. checked the battery voltage using a Multimeter and its delivering the required voltage. Please solve my problem. — Sharath

Solution: Hi Sharath. Installing a third party app like Wake Lock to fix a certain issue is  never a permanent solution. Unless the main cause of the problem is addressed, you can expect that it will return.

We know nothing much about your phone’s history including the possible reasons that may have led as to why your Note 4 now fails to power back on so it can really be anything at this point. We know that there are a lot of Note 4 users that find their device working fine after installing Android’s latest update, we always expect to receive reports of problematic cases simply because Note 4’s hardware was designed to work with older Android versions. Installing the latest Android iteration to it can put a strain on the hardware, leading to all sorts of problems. There’s never any official Samsung explanation why there a lot of Note 4 devices failing after an update but the general rule, if a broken device can’t be fixed by software troubleshooting, bad hardware must be to blame.

If you haven’t tried it yet, we suggest that you manually install the older yet working Android version for your device. We know this is not ideal but it’s the only effective way to allow users of Note 4 to continue using their devices that suffered problems after installing Marshmallow and/or Nougat.

Problem 9: Galaxy Note 4 screen showing green strip on top, screen remains black and won’t turn on

I had my phone in my bag on a chair and when I went to go get it and my bag was on the floor. There were scratches on the front of it. The screen is totally black but when I 1st tried to turn it on there was a green strip on the very top of the screen that appeared. There is a blue light blinking on top (like my email notification) and the lights at the bottom still work. I have the Samsung Galaxy Note 4. — Brittany-cats

Solution: Hi Brittany-cats. Boot the phone to Recovery or Download mode and check if you can get the screen to work normally. If that green strip on top remains when the device is on Recovery or Odin mode, you’re out of luck. That’s a sign of a damaged screen and you must have the phone repaired or replaced. The same is true if the screen stays black and won’t show anything.

Here are the steps on how to boot the phone to Recovery Mode or Download mode:

Boot in Recovery mode:

  1. Charge the phone for at least 30 minutes.
  2. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  3. When the Samsung Galaxy logo shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  4. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  5. Using the Volume Down key, navigate through the options and highlight ‘wipe cache partition.’
  6. You can either wipe the cache partition or do a factory reset when in this mode.

Boot in Download Mode:

  1. Charge the phone for at least 30 minutes.
  2. Press and then hold the Home and Volume DOWN keys, then press and hold the Power key.
  3. When the Samsung Galaxy logo shows on the screen, release the Power key but continue holding the Home and Volume DOWN keys.
  4. Wait until the Download screen appears.
  5. If you can boot the phone in download mode but not in other modes, that means that your only way out may be to flash a stock or custom firmware.
  6. Use Google to look for a guide on how to do it.

If you can, kindly include the exact error messages you are getting to give us an idea where to start. If you have already tried some troubleshooting steps before emailing us, make sure to mention them so we can skip them in our answers.


Problem #1: Galaxy Note 4 shuts down when battery has low power level

I have had my Note 4 for a while and recently I’ve been having some trouble with it. For starters, the phone will die anywhere from 28% to 40%, then when i plug it in to charge it starts charging from where it left off (say it died on 38%, it will say its charging and currently at 38%).

Also, not sure if it is related to this problem but unless i have fast charging enabled in the battery menu, it will not charge significantly ( it will charge maybe 5%-10% in a 7 hour span). Not sure if this is a power IC problem or the battery but i have a replacement on the way since i have heard that it fixes the turning off at 28-40 but the slow charging baffles me. — Koby

Solution: Hi Koby. The only way to know if a particular hardware component is defective or not is to check it physically so tests can be done. Unless you have done that, you must try doing software troubleshooting first.

And speaking of software troubleshooting is concerned, we recommend that you try battery recalibration first. Doing so will help the operating system read the correct battery levels. Sometimes, Android can lose track of correct battery readings so doing this procedure will help it do the job properly. Here’s how to do it:

  1. Use the phone by playing games or doing tasks to hasten power discharge, until the phone turns itself off.
  2. Turn the phone on again and let it turn itself off.
  3. Charge the phone without turning it back on.
  4. Wait until the battery says it fully charged to 100%
  5. Unplug the charger and turn the phone on.
  6. If the phone says it’s not 100% anymore, turn it off, plug the charger back in and wait until 100% charge is reached.
  7. Unplug the charger the turn the phone on again.
  8. Use the phone until you drain the battery down to 0.
  9. Repeat the cycle once.

If battery calibration won’t work, try doing a factory reset and see how the device charges. Make sure that you let the phone run for at least 24 hours or longer without installing any app or update. If nothing changes immediately after a factory reset and during the observation period, you can assume hardware may be to blame.

For reference, here are the steps on how to factory reset your device.

  1. Turn off the Galaxy Note 4 completely.
  2. Press and hold the Volume Up and the Home keys together, then press and hold the Power key.
  3. When the Note 4 vibrates, release both the Home and Power keys but continue holding the Volume Up key.
  4. When the Android System Recovery shows on the screen, release the Vol Up key.
  5. Using the Volume Down key, highlight ‘wipe data / factory reset’ and press the Power key to select it.
  6. Now highlight ‘Yes — delete all user data’ using the Vol Down key and press the Power key to begin the reset.
  7. When the master reset is complete, highlight ‘Reboot system now’ and hit the Power key.
  8. The Note 4 will restart but it will be longer than usual. When it reaches the Home screen, then begin your setup.

Factory reset will wipe the phone clean so make sure that you create a backup of your files before doing it.

Problem #2: Galaxy Note 4 running very slow

For the last 3 days my phone has been running very slow. The apps take around 2 minutes to load. When they do load I’m faced with a white screen for a further minute. it keeps resetting itself, freezing at random points on anything i try to do — launch an app, read and email, send a message etc. When making a call i am unable to hang up because i have a black screen apart from a white phone icon in the top left corner and the time etc in the right. The lock and home button do not respond for a while then after about 2 minutes it will keep flashing up with the lock screen as if it is trying to catch up with itself after me pressing the button so many times. i have reset the phone, removed the battery numerous times just to reboot it as it completely locks up. I have not installed any apps recently or had any recent updates, i have removed a load of apps/ games from my phone to see if this helps but with no improvement. — Cassie

Solution: Hi Cassie. Slow performance issue like the one you’re talking about here can be caused by a number of things so your first task is to narrow down the possible causes. These causes can include the following:

  • a corrupted system cache
  • an operating system glitch
  • malware
  • bad battery
  • an unknown hardware issue

To see if it’s a corrupted system cache, make sure that you wipe the cache partition first. Sometimes, updates or new apps can lead to instability issues as well as slow performance. Wiping the cache partition should delete the old system cache and create a new one. It’s a simple maintenance step that you should do once every few months, especially if you tend to install a lot of apps. To wipe the cache partition, follow these steps:

  1. Turn off the Galaxy Note 4 completely.
  2. Press and hold the Volume Up and the Home keys together, then press and hold the Power key.
  3. When the Note 4 vibrates, release both the Home and Power keys but continue holding the Volume Up key.
  4. When the Android System Recovery shows on the screen, release the Volume Up key.
  5. Using the Volume Down key, highlight the option ‘wipe cache partition’ and press the Power key to select it.
  6. When the wiping of the cache partition is finished, highlight ‘Reboot system now’ and hit the power key.

Should nothing change after wiping the cache partition, you can then proceed to factory reset. Factory reset is a must-do troubleshooting step especially that you don’t provide us with any helpful piece of history about your device. If bad hardware is causing the lag or slow performance, factory reset should not change anything. Like what we said above, you must observe how the phone works immediately after a factory reset to see any difference. If there’s no positive change, consider getting a new battery or simple send the phone to Samsung for repair or replacement.

Problem #3: Galaxy Note 4 can’t move files to SD card

I can’t copy or move any files on to my SD card. I also can’t move them from folder to folder on the SD card. However I can move them from the SD card to my phone memory without any problems. And files already on the SD card seem to work fine, it’s just moving them that does not work.

I have tried using the “My Files” app but it did not work.

Sometimes, after restarting the phone I can move files without problems for a couple of minutes. And moving files from my PC to the SD card is really weird. When doing this it will move the files, they will show on the PC that the files have been moved but on the phone only some of them will actually have been moved, and the other files will be absent. After reconnecting the phone to the PC, it will also show that only some of the files have been moved. These problems only occur when moving files to the SD card or their location on the SD card.

Also this can’t be a problem with the phone because I had the same problem with the same SD card on my old phone (Galaxy S3) as well. — Arnold

Solution: Hi Arnold. If the same issue occurs when using the same SD card on another device, then something must be wrong with the SD card. Try to reformat the SD card using your phone and try to move files again. If the problem stays, have the SD card replaced.

Problem #4: Galaxy Note 4 randomly shuts down | Galaxy Note 4 power button not working properly

I have a Galaxy Note 4 and for the past couple months the power button stopped working. I figured the button itself went bad but if I press it hard and quickly, it will sporadically, jump straight to the long hold menu to turn off, restart or put it in Airplane mode. The troubles don’t stop there, if it dies, sometimes it goes completely empty. sometimes it can turn off at 35% or thereabouts, it will not turn back on. It is getting stuck in the reboot phase.

If I pull the battery out (when already off) and put it back in it will give a quick vibration after 2-5 seconds, show the black screen with “Galaxy Note 4” in white, but that will not stay the full length of time it’s supposed to and then go off. If I pull the battery out and put it back in and then hold the volume down and home buttons it will show that screen, sometimes it’s momentary, other times I can press the volume up or down button to try to get it to do something but then it dies again. The only solution I have found was on youtube people have said to tap the phone on a hard surface around the power button area for a few seconds or taps. Then put the battery in and see if it vibrates. If it does, repeat that process until it does not vibrate and then hold the power button and the phone will restart correctly. This has happened around 3 times now, and it is unbelievably frustrating and annoying. I have spent around 45 minutes to an hour doing this. After the phone restarts there’s an uncertain amount of time that the power button works correctly, then will stop working as mentioned above. To me, that sounds not like a hardware issue, but a software issue. So my question is, could this be related to the 5.0.1 software that I’m running because I have never had this issue with any previous versions? Do you advise going back to a previous revision and seeing if that fixes it, or do you think there’s something else going on? I would really rather fix this phone which works perfectly otherwise, instead of paying $700 for a new one. Please let me know if you can help. Thank you. — Greg

Solution: Hi Greg. First of all, you already know that the power button is not working properly. A bad power button means that the metallic contact on the physical button may be causing the phone to randomly trigger a shut down command. We don’t think it’s a coincidence that the phone has a random reboot issue and bad power button at the same time. This can also be the reason why the Youtube remedy you’re doing has not fixed the issue. The hit-and-miss situation is most probably due to the fact that the power button mechanism does not work as expected.

If you think it’s a software issue though, consider doing the basic software troubleshooting such as wiping the cache partition, observing in safe mode, and factory reset. If the issue remains after doing these three procedures, we strongly recommend that you have the phone’s power button fixed.

For reference, here are the steps on how to do the software troubleshooting:

How to wipe the cache partition

  1. Turn off the Galaxy Note 4 completely.
  2. Press and hold the Volume Up and the Home keys together, then press and hold the Power key.
  3. When the Note 4 vibrates, release both the Home and Power keys but continue holding the Volume Up key.
  4. When the Android System Recovery shows on the screen, release the Volume Up key.
  5. Using the Volume Down key, highlight the option ‘wipe cache partition’ and press the Power key to select it.
  6. When the wiping of the cache partition is finished, highlight ‘Reboot system now’ and hit the power key.

How to boot the phone to safe mode

  1. Turn off the phone completely.
  2. Press and hold the Power key and the Volume Down key.
  3. When the phone starts to boot, release the Power key but continue holding the Volume Down key until the phone finished restarting.
  4. Safe mode will be display at the lower left corner; you may release the Volume Down key now.

How to factory reset the Galaxy Note 4

  1. From the Home screen, tap the Apps icon.
  2. Launch Settings and scroll to ‘User and Backup’ section.
  3. Tap Backup and reset.
  4. If you want, you can tick the checkboxes next to Automatic restore and Back up my data.
  5. Tap Factory data reset.
  6. Touch Reset device.
  7. You may be asked to enter your PIN or Password.
  8. Tap Continue and then Delete all.

Problem #5: Galaxy Note 4 won’t turn on after being inactive for 18 months

I have a Galaxy Note 4 that was working fine then switched off and put in drawer for 18 months. Now device won’t work. Charges but nothing on screen, red service lights then goes green when charged. Turn on seems ok, it vibrates, soft keys light and then blue light flashes BUT nothing on screen so I have no idea what is going on, if anything. As phone was fine am reluctant to think screen has mysteriously failed.

Also, I’m not fully convinced it is booting normally. Button presses for reset etc. do not get anything from screen so no idea if there is anything going on or not. Are you able to help?? As, I say phone was fine before and in excellent condition, no damage so optimistic it is ok but thanks. — Bcrux

Solution: Hi Bcrux. We think the cause of the problem is a bad battery. 18 months is a long way to let keep a Lithium-ion battery bleed power without recharging. Keep in mind that a battery of this type gradually loses power even when it’s not being used. The ideal remaining battery percentage level  should be around 80 percent before you set it aside for a long time. This will ensure that there’s enough power to keep internal protection circuits alive. Allowing a lithium-ion battery to fully discharge, also called “deep discharge,” will cause the phone to lose its ability to keep a charge. If your phone’s battery has been deep discharged within the 18-month period, there’s nothing more that you can do right now but to replace it.

Technically, if the phone’s battery percentage level shows 0%, it doesn’t really mean the battery is fully empty. It still retains certain amount of power to keep its circuits alive.

Bad battery may be the reason why the phone appears unable to boot properly, or even show anything on the screen. Get a new battery and see how  it goes.

Problem #6: Galaxy Note 4 screen heats up when phone is in use

Samsung Galaxy Note 4, about 2 years old. Hello! I have recently been having hardware problems with my Samsung Galaxy Note 4. About 2 weeks ago, the phone began to have issues regarding the screen and heat. The upper-left part of the screen would begin to heat up very rapidly with only very minor use. Soon after, the screen would begin flickering, beginning with a few lines here and there from shapes, to the entire screen flickering and moving up and down like an old tape, and the screen going black. Turning off the screen by tapping POWER and turning it back on fixes it, but only for about 5 seconds. I am required to let the phone cool off after every 10 minutes of use. I am pretty sure this is a hardware problem. A safe mode boot did not fix it, and neither did a cache clear. Some help would be very much appreciated; I cannot afford a new phone currently, but may be able to afford repairs, if needed. Thank you in advance. — Myles

Solution: Hi Myles. The symptoms you mention here are definitely consistent with a hardware problem but we still recommend that you do a factory reset first. If the same symptoms remain after a factory reset, that’s clear proof that there’s hardware malfunction. In that case, we suggest that you  let a professional check it so you’ll know if repair can be done, or if replacement is a better option. Our blog does not provide hardware troubleshooting and solutions so if you want to do the repair yourself, consider looking for guides from other websites.

Bear in mind that phone repair, just like a typical gadget repair, requires a solid understanding of electronics, not to mention the needed tools to do the job. If you think you have the skills and tools for a Note 4 repair, then go ahead.

Wet Galaxy S7 won’t charge via USB, won’t download new emails after an update, other issues

Hello Android community! The #GalaxyS7 is water-resistant but what happens if water or some moisture are caught inside the USB port? In this post, we discuss what you need to do if you happen to expose your phone to water and you encounter a charging problem with it. We also cover 5 more S7 issues so we hope that this post can be a helpful reference for you.

Below is the complete list of issues addressed in this material:

  1. Wet Galaxy S7 won’t charge via USB
  2. Galaxy S7 email app won’t download new emails after an update
  3. Galaxy S7 only works when connected to a charger
  4. Galaxy S7 charging port not working properly
  5. Galaxy S7 multiple issues after installing Android update
  6. Galaxy S7 slow performance issue after an update

If you are looking for solutions to your own #Android issue, you can contact us by using the link provided at the bottom of this page, or you can install our free app from Google Play Store.

When describing your issue, please be as detailed as possible so we can easily pinpoint a relevant solution. If you can, kindly include the exact error messages you are getting to give us an idea where to start. If you have already tried some troubleshooting steps before emailing us, make sure to mention them so we can skip them in our answers.


Problem #1: Wet Galaxy S7 won’t charge via USB

Yesterday, my Samsung S7 phone fell into the toilet (clean bowl, whew!) and I quickly retrieved it. It didn’t shut off and seems to be working ok. I noticed that it wouldn’t charge with the charger inserted at the charging port but it worked with the platform charger. I placed it in the rice over night as per your instructions and that I had heard of this technique but never turned it off (afraid that it would not turn back on). Again, so far the phone appears to be okay. Do you think I am in the clear that it will be fine? —         Cookmoore4u

Solution: Hi Cookmoore4u. The Galaxy S7 is water-resistant so there’s no reason for you to be concerned if you drop it in shallow water. The IP68 certification on this device should be enough to protect it from water damage as long as you don’t submerge it deeper than 1.5 meters for 30 minutes. The thing that should concern you though is the unnecessary shock from the fall, especially if it hit the solid portion of the bowl.

Because the Galaxy S7 does not have external protection against water penetration in the charging port area, it is equipped with a special feature that prevents it from charging via cable if the system detects moisture. This feature usually shows a corresponding error when there’s water particles detected in the charging port area that says: “Check port: Moisture has been detected. To charge your device, make sure that your charger/USB port is dry.” If your phone does not display this error but refuses to charge, that means that it’s still not safe to charge by cable. You must first ensure that the charging port is dry.

To do that, first you need to make sure that you wipe the phone dry using a clean soft cloth. Then, you want to shake the phone hard, with the charging port facing downward to remove any excess water. Do this until your phone charges again. Alternatively, you can use a hair dryer to dry the phone for a few minutes. Be careful not to heat your phone up too much as that might damage it. Again, wipe the phone until it becomes dry, or until all moisture is gone. If you think that the phone is dry, restart it and try charging by cable again.

Problem #2: Galaxy S7 email app won’t download new emails after an update

Downloaded the newest system upgrade to my Samsung S7. Now I can’t receive emails from the (Microsoft Exchange) Microsoft 365 server – work email. It “syncs” but the newest emails still won’t show up. Turned off and restarted phone and also deleted/added account. I received the newest emails to when the new account was turned on (newly added) – but can’t receive new emails. Having to use Microsoft 365 on Google to receive any emails. Any suggestions? — Marc

Solution: Hi Marc. The first thing that you want to try here is to wipe the cache partition to ensure that the phone is using a good system cache. This is a standard troubleshooting step when it comes to issues following a system update. Here’s how it’s done:

  1. Turn off your Samsung Galaxy S7.
  2. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  3. When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  4. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  5. Using the Volume Down key, navigate through the options and highlight ‘wipe cache partition.’
  6. Once highlighted, you may press the Power key to select it.
  7. Now highlight the option ‘Yes’ using the Volume Down key and press the Power button to select it.
  8. Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.
  9. The phone will now reboot longer than usual.

If refreshing the system cache won’t help, the next thing that you want to do is to delete the cache and data of the problematic email app. Here’s how:

  1. Open the Settings menu either through your notification shade (drop-down) or through the Settings app in your app drawer.
  2. Navigate down to “Apps”. This may be renamed to something like Applications or Application Manager in OEM skinned versions of Android 6.0.
  3. Once in there, click on an application.
  4. You’ll now see a list of stuff that gives you information about the app, including Storage, Permissions, Memory Use, and more. These are all clickable items. You’ll want to click on Storage.
  5. You should now clearly see the Clear Data and Clear Cache buttons for the application.

Finally, if you think it’s worth the hassle, consider doing a factory reset to fix the problem. Remember, factory reset will delete all user data in the phone’s internal storage device so make sure that you create a backup first.

To factory reset your S7, follow these steps:

  1. Turn off your Samsung Galaxy S7.
  2. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  3. When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  4. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  5. Using the Volume Down key, navigate through the options and highlight ‘wipe data / factory reset.’
  6. Once highlighted, you may press the Power key to select it.
  7. Now highlight the option ‘Yes — delete all user data’ using the Volume Down key and press the Power button to select it.
  8. Wait until your phone is finished doing the Master Reset. Once completed, highlight ‘Reboot system now’ and press the Power key.
  9. The phone will now reboot longer than usual.

Problem #3: Galaxy S7 only works when connected to a charger

I own a Samsung Galaxy S7. Yesterday I realized it was shut off and when I tried to turn it back on it wouldn’t power up. So I plug the charger in and turned it on and it worked but when I tried unplugging it from the charger and it automatically powered off. I also tried factory reset restoring it and also would not work. so my phone only works when it’s plugged into the charger and when it’s plugged into the charger it gets up to 86% charged and stays there.        — Peyton

Solution: Hi Peyton. There’s only one thing that we can suggest for you — battery recalibration. If this won’t work, that means you need to send the phone in so the hardware can be examined. The problem may be limited to the battery or something serious such as a bad power IC or an unknown logic board glitch. Whatever it is, the best thing that you may have to do is to get a replacement. If your phone is still covered by a warranty, Samsung may replace your phone for free. Otherwise, you may have to pay for either the repair or replacement.

For reference, here are the steps on how recalibrate the battery:

  1. Use the phone by playing games or doing tasks to hasten power discharge, until the phone turns itself off.
  2. Turn the phone on again and let it turn itself off.
  3. Charge the phone without turning it back on.
  4. Wait until the battery says it fully charged to 100%
  5. Unplug the charger and turn the phone on.
  6. If the phone says it’s not 100% anymore, turn it off, plug the charger back in and wait until 100% charge is reached.
  7. Unplug the charger the turn the phone on again.
  8. Use the phone until you drain the battery down to 0.
  9. Repeat the cycle once.

Problem #4: Galaxy S7 charging port not working properly

My phone is only a few months old. The charging/data port will only accept a charge if I position the cord just right and then tape it to the phone. Even then it is very difficult to get the phone to charge. I have tried other cords. In my opinion the phone should have been designed with the old style round DC charging port, and a different port for data. Or an inductive charging system so it is not subject to the every day friction of plugging and unplugging. Very frustrated. — Schlip76

Solution: Hi Schlip76. Your phone’s charging port must be damaged so the only fix for it is hardware fix too, which means repair. If possible, let Samsung do the repair for you. Better still, try to check if you can have the device replaced.

Problem #5: Galaxy S7 multiple issues after installing Android update

Hi there and thank you for your very helpful advice site. I did an update a few days ago. My phone is quite new and worked fine although a little slow, and recently I have noticed the home screen is a bit wonky. Doubled up time digits and other indicator images across the top of the screen. Since doing the update, the messaging app crashes every time I try to go into the emoji menu. 🙁 

I would like to know, firstly, how to do a back up of my data, and what would disappear after a reset – e.g would I lose all of my text conversations?

Secondly, is there a way to fix this crashing problem?

Thirdly, can I delete the update of the OS? Thanks so much. — Kat

Solution: Hi Kat. If the most recent Android update did not go well for you, make sure that you do the standard troubleshooting for the issue as detailed above. Basically, what you need to do includes the following:

  1. wipe the cache partition
  2. install app and system updates (if any are available at this time)
  3. factory reset

The steps for wiping the cache partition and factory reset are provided above.

In creating a backup, we recommend that you use the official Samsung Smart Switch app so you can do it easily. You need a computer where you can install the Smart Switch app. Once you have the app installed on your computer, it’s just a matter running the app and hooking your phone to your computer.

For reference, below are the exact steps on how to use Smart Switch to back up your files.

  1. Install Smart Switch on your PC.
  2. Connect your new Galaxy device to the desktop.
  3. Now open the Smart Switch app on your computer, and connect your Galaxy device to it with a USB cable.
  4. Back up your old Galaxy device by clicking the ‘Backup’ option on the Smart Switch app. Remember that you need to unlock the lock screen before proceeding.

Is there a way to fix this crashing problem? Well, we hope that wiping the cache partition would but if not, the factory reset option should definitely fix it. If you don’t want to do factory reset right away, you can also wipe the cache and data of the messaging app to see if that will make any difference. Remember, clearing the data of an app is the virtual equivalent of uninstalling the app so if you want to save some conversations, make sure to create a backup first.

To delete an app’s cache and data, follow these steps:

  1. Open the Settings menu either through your notification shade (drop-down) or through the Settings app in your app drawer.
  2. Navigate down to “Apps”. This may be renamed to something like Applications or Application Manager in OEM skinned versions of Android 6.0.
  3. Once in there, click on an application.
  4. You’ll now see a list of stuff that gives you information about the app, including Storage, Permissions, Memory Use, and more. These are all clickable items. You’ll want to click on Storage.
  5. You should now clearly see the Clear Data and Clear Cache buttons for the application.

Can I delete the update of the OS? No. system updates can’t be removed from the system. If you want to, you’ll have to risk bricking your phone by manually flashing an older Android firmware. If you’re interested how to do it, try to do some research on how to flash firmware on Samsung devices. For that, Google will surely come handy.

Problem #6: Galaxy S7 slow performance issue after an update

Hello. I have a Samsung Galaxy S7 that I recently got. My carrier is Rogers. The problem with my phone is that sometimes after opening an app, scrolling too quickly, or skipping too many songs, my phone freezes. It’s like the processor can’t keep up with the phone. I empty my cache often and remove miscellaneous files from my storage. But it barely has an impact. After the phone freezes, I have to restart it by pressing and holding the power button. Once it restarts it starts working again. This is just super annoying. I would greatly appreciate any suggestions. Thanks. — Joyshah99

Solution: Hi Joyshah99. Slow performance can be an indicator of both software and hardware problem so your first task is to narrow down all possible causes. The general rule is to exhaust all software troubleshooting. If nothing changes after doing all relevant software troubleshooting, you can assume that bad hardware is to blame. The list of software procedures that you must do for this issue does not vary much from other issues mentioned above. Slow performance is a tricky problem and its cause can be hard to pin down. Sometimes, this type of problem can be caused by inefficient or poor coding so it’s very likely that there’s something that you can do about it. In some cases, a corrupted system cache is the cause so make sure that you do the steps on how to wipe the cache partition provided above.

In a lot of cases, Android users tend to forget the fact that installing a system update does not necessarily mean installing app updates. Is that problematic? You bet it is! Not all apps are created equal. Many popular apps can be financially rewarding for a developer, which means that they can afford to spend resources to regularly monitor  and update their product. Some apps may not be too lucky and they may not receive regular patches or updates from their respective developers. And this is where the problem usually lies. If an app can’t cope with the ever changing Android environment, there will come a time that it can create a conflict with the most recent Android version. This is especially true for old apps that may no longer receive necessary updates to work with, say, Android Nougat. If you install such an app in your phone, it may become incompatible, which can lead to instability or slow performance problem. That said, it’s your responsibility to make sure that all apps are updated and compatible. If you have a lot of apps, invest some time to research if each one is compatible with the current OS version.

Also, make sure that you lessen the number of apps in your device. If you haven’t used an app for the last 2 weeks, chances are, it’s not that important. Be sure to uninstall it. Keep in mind that the more apps you install, the higher the chance of encountering bugs due to higher number of possible points of failure.

Finally, if all else fails, do a factory reset. It’s a bit drastic but’s a proven effective solution for post-update issues.

Now, if factory reset won’t improve the situation and the phone continues to freeze, there may be a hardware malfunction somewhere. To find out what it is, send the phone in, or better still, have it replaced.

When describing your issue, please be as detailed as possible so we can easily pinpoint a relevant solution. If you can, kindly include the exact error messages you are getting to give us an idea where to start. If you have already tried some troubleshooting steps before emailing us, make sure to mention them so we can skip them in our answers.


Problem #1: Galaxy S5 screen keeps flickering

After receiving my second hand S5, after few months the lower part of the screen about one forth started to flicker in a much brighter light than the rest of the phone screen. I thought nothing of it at the time. However, what happened today was when the lower part started to flicker it was in a normal light and it’s as if the rest of the screen light had gotten darker( I mean i could have still read whatever was there). I decided to turn off my phone because I just guessed that it needed sometime (that maybe i’m just using it too much). Anyways, after about 15 to 30 mins i turned it back on. The light still flickered at the bottom, so decided to hit the screen. I did  and shortly after everything seemed fine (normal again). Unfortunately a few seconds after that the top part (the other 3 quarters) started to flash with a red light and the lower part(1 quarter ) flashed with a yellow light. Now the lights are flashing fast and i hurts my eyes to look at my phone. Please help me. — Krystaphel

Solution: Hi Krystaphel. Anytime a screen starts to behave abnormally, it’s almost always due to hardware malfunction. We don’t know the full history of your phone to say for certain if that’s the case but the description you provide here is consistent with a failing screen. To check if that’s the case, do a factory reset and see if that will change anything. If the screen behaves exactly after a factory reset, that’s a sign of a bad hardware. In this case, you need to send the phone in so the hardware can be repaired or replaced.

To factory reset your phone, kindly follow these steps:

  • Turn off your Samsung Galaxy S5.
  • Press and hold the Volume Up, Home and Power keys together.
  • When the device powers on and displays ‘Power on logo’, release all keys and the Android icon will appear on the screen.
  • Wait until the Android Recovery Screen appears after about 30 seconds.
  • Using the Volume Down key, highlight the option, ‘wipe data/factory reset’ and press the Power key to select it.
  • Press the Volume Down button again until the option ‘Yes — delete all user data’ is highlighted and then press the Power key to select it.
  • After the reset is complete, highlight ‘Reboot system now’ and hit the Power key to restart the phone.

NOTE: Factory reset will delete all user data such as photos, videos, contacts, etc. Make sure that you back them up before proceeding.

Problem #2: Galaxy S5 with Tracfone account can’t make outbound calls

I have an unlocked Samsung Galaxy S5 from ATT GSM for use with a Tracfone account. I have installed the SIM provided by Tracfone and transferred my service and I can make outbound calls but I haven’t tested inbound yet. My account at Tracfone shows that my that the minutes, data and sms have all transfered to the new sim. I can get data via wifi, but there is no switch to turn mobile data on. I have looked in settings, notifications, quick notifications and every where else I can think of, but the switch doesn’t exist and the service is turned off. I have done a factory reset with no result. Do I need to go through that APN stuff with Tracfone? Bless you if you can help, thanks if you cant. — Gordon

Solution: Hi Gordon. In an ideal world, your phone is supposed to reconfigure all APN settings once you insert an active SIM card but if that didn’t happen, yes, you should work with Tracfone to fix the issue. There may be a provisioning issue that needs to be addressed on Tracfone’s end so make sure that you work with them to make their services work on your phone. There’s nothing a third party like us can do in this situation so the responsibility of making sure everything is working falls on your carrier’s shoulders.

Problem #3: Galaxy S5 lags a lot after installing Android Marshmallow

Hi. My name is James. I own an S5 and have had it for around 2 years now. It’s a great phone and I love it but when Samsung did updates a while ago it drastically slowed down the operating system. I currently have the 6.0.1 updated and I think I have come all the way from 4.0.1. Is there a way to speed the phone up? It seems to have a lot of lag. If you are texting it’s always letters behind. If you want to load a app like the camera or the internet it takes a while to load. It just has a lot of lag all the way around. Does any of this have anything to do with memory? I have a SD card in the system. Please let me know if you could help.        — Jamesbielamowicz

Solution: Hi Jamesbielamowicz. Although Samsung released a Marshmallow update for the Galaxy S5, there will be a noticeable slow down in terms of performance as this device was optimized for Android KitKat. The Galaxy S5’s hardware may run Marshmallow but at a much slower pace. This is the reason why a lot of S5 users who switched to Marshmallow are having problems. We have our own Galaxy S5 updated to Marshmallow ourselves and we can say that it’s become slower in its general performance compared to when it was running Lollipop. Marshmallow is best suited for newer and faster Samsung flagship devices like the S6 and S7 so yes, memory and processing power of the S5 can play a role when it comes to providing a smooth Marshmallow experience.

There are, of course, other reasons why an Android device can slow down after installing an update so we suggest that you do the basic stuff like wiping the cache partition, installing app and system updates, and factory reset to see a difference.

For reference, below are the steps on how to wipe the cache partition and factory reset in Galaxy S5.

How to wipe the cache partition in an S5

  • Turn off the device.
  • Press and hold the following three buttons at the same time: Volume Up key, Home key, and Power key.
  • When the phone vibrates, release the Power key but continue to press and hold the Volume Up key and the Home key.
  • When the Android System Recovery screen appears, release the Volume Up and Home keys.
  • Press the Volume Down key to highlight ‘wipe cache partition.’
  • Press the Power key to select.
  • When the wipe cache partition is complete, ‘Reboot system now’ is highlighted.
  • Press the Power key to restart the device.

How to factory reset Galaxy S5

  • Turn off your Samsung Galaxy S5.
  • Press and hold the Volume Up, Home and Power keys together.
  • When the device powers on and displays ‘Power on logo’, release all keys and the Android icon will appear on the screen.
  • Wait until the Android Recovery Screen appears after about 30 seconds.
  • Using the Volume Down key, highlight the option, ‘wipe data/factory reset’ and press the Power key to select it.
  • Press the Volume Down button again until the option ‘Yes — delete all user data’ is highlighted and then press the Power key to select it.
  • After the reset is complete, highlight ‘Reboot system now’ and hit the Power key to restart the phone.

Problem #4: Galaxy S5 can’t send SMS

Your Samsung Galaxy S5 Problems  columns have been very informative. I’ve looked for my issue, but haven’t seen it.

My Galaxy S5 updated to Lollipop 3 or 4 days ago. Since then, none of my text messages I’m trying to send will go. The only information I get is that my attempt to send has failed. Tonight I called my daughter and had her send me a text message, which I did receive. But the reply I tried to send once again failed. Attempts to resend failed.

I’ve gone into settings and checked the different options. I don’t believe anything changed there. I’ve restarted phone and also did a full power off and let it be before turning back on.

Any help you can provide will be greatly appreciated. Thanks for all your help. — Bonnie

Solution: Hi Bonnie. Make sure that you check the Message Center number. Something must have changed it. An incorrect Message Center number is one of the common reasons why a device can send outbound SMS. To check, follow these steps:

  • Press Messages.
  • Press the menu icon.
  • Press Settings.
  • Press Text messages.
  • Press Message center.
  • Key in the Message Center number and press OK.

A Message Center number is specific to a carrier. Make sure to get the correct number from your carrier before changing it.

If the phone has already the correct message center number configured, the next thing that you want to do is to delete the messaging app’s cache and data. Here’s how:

  • Open the Settings menu either through your notification shade (drop-down) or through the Settings app in your app drawer.
  • Navigate down to “Apps”. This may be renamed to something like Applications or Application Manager in OEM skinned versions of Android 6.0.
  • Once in there, click on an application.
  • You’ll now see a list of stuff that gives you information about the app, including Storage, Permissions, Memory Use, and more. These are all clickable items. You’ll want to click on Storage.
  • You should now clearly see the Clear Data and Clear Cache buttons for the application.

If both these procedures fail to fix the problem, make sure to let your carrier know about it so they can help find a solution.

Problem #5: Galaxy S5 charges but won’t turn back on

Hi. My Samsung S5 battery drained down to 1% while on charge and in use so we turned the device off. Now it won’t turn back on or even show that the charger is plugged in. it is just totally dead now but gets hot if the charger is plugged in.

I took it to a phone repair shop and they put in a new battery and put it on charge. It shows on the screen that it’s on charge with a new battery in but it just stays at 0% and still won’t turn on even though we know it’s a fully charged battery (by checking in another phone). They say it’s the motherboard and that its unfixable. Is this right or could i get a new motherboard? Nobody has opened it up to look inside. Thanks in advance. — Kirstie

Solution: Hi Kirstie. It must be a motherboard problem, like what the service center found out. A power IC or integrated circuit may no longer be working causing the phone to simply heat up while charging, while not really completing the whole cycle of powering the entire system. A motherboard issue is an expensive repair procedure but does not give a 100% guarantee of working so we highly suggest that you get a phone replacement instead. We don’t want you to spend hundreds of dollars for a repair and parts replacement only to end up having a non-working device.

Problem #6: Galaxy S5 freezes when typing | Galaxy S5 freezes randomly

Hello. I came across your article while searching for problems with my phone. My phone tends for freeze up/lag a lot in the last month.

It lags when:

-My phone is locked and I hit the power or home button. The screen quickly flashes on and off, and will stay dark until a minute or two later when it finally releases itself and then I can use the phone again.

-When I’m texting. The screen freezes and can’t type anything. After a few moments the screen goes black. I hit the power/home button and everything works again.

-I’ll be randomly using the phone, and then the phone freezes and like the previous post, have to wait until the freeze/lags releases the phone before I can use it again.

Note:

– The freezing/lagging happens randomly. It can happen after 6 hours of usage, or after 5 minutes after powering up my phone.

Is there a way to isolate the problem and figure out what is causing this? Thanks! — Andrew

Solution: Hi Andrew. Your situation can be caused by a number of things, including a possible hardware malfunction so you must be a series of software troubleshooting to narrow down the causes.

The first thing that you must do is to check if the system cache is corrupted or outdated. You can do that by wiping the cache partition (steps provided above).

If the cache is okay, or that the problem continues after clearing the cache partition, you also need to verify if a third party app is causing the trouble. To do that, you must boot the phone to safe mode and observe the phone for at least 24 hours. Here are the steps on how to restart your S5 to safe mode:

  • Press and hold the Volume Down and Power keys for 20 to 30 seconds.
  • Once you see the Samsung logo, release the Power key immediately but continue pressing the Volume Down key.
  • Your phone should continue booting up and you will be prompted to unlock your phone as usual.
  • You will know if the phone successfully booted in safe mode if the text “Safe mode” is displayed at the lower-left corner of the screen.

Instability problems can sometimes be caused by other apps simply because they are incompatible with the current operating system version. Make sure that you only install compatible apps. Try to uninstall those that you are unsure of. Old or outdated apps built years before may no longer run properly with new Android updates so go over your list of apps and try uninstall old ones. You will usually know if an app is problematic by checking reviews posted by other users. Try to visit the installation page of your apps in Google Play Store and see if a developer has indicated that such app is not compatible with the OS running on your device. Of course, you can also check the reviews to see what others are saying about it. Keep in mind that there’s no way to know what is causing a problem like yours so you must invest time and effort in getting down to the bottom of the issue.

Factory reset is a drastic but effective solution for everything that’s firmware or operating system related. However, it may not work if the problem is due to an app that you missed to check, or if the issue is hardware in nature. If you do a factory reset, make sure that you observe how the phone works for a day without installing anything. This will allow you to determine if the problem returns while the slate is clean. If it does, then that’s an indication of a hardware issue.

It can be a battery problem too so before sending the phone to Samsung for repair or replacement, make sure that you try a new battery first.

Problem #7: Cannot install update to Galaxy S5 when used in another network

Hi. My mom gave me her Samsung S5. She was with Telus and I’m with Fido so she paid to have it unlocked. The phone worked perfectly fine with Telus. When I put the Fido SIM card in and reset the phone to factory settings, it won’t update. It says it’s already up-to-date. it turns off on me and turns back on saying SIM card not detected. When I turn it off and back on sometimes I get the Fido service bar back, but not very often recently does that work. When the Fido service is connected to phone and detecting SIM card, it only texts; it won’t make calls and it says it’s out of service area. It won’t call voicemail box either says, Ontario. I’m in Alberta Canada. Any help would be great.

I’m wondering if I put a Telus sim card in and update the phone through that service would it work. Any help would be greatly appreciated. Thank you. — Dylan

Solution: Hi Dylan. First of all, OTA (over-the-air) update won’t work if you use an unlocked phone (like your Telus S5) in another network (like Fido). Carriers only release updates to devices actively registered on their network and using their provided software. Since the software in your phone is still a Telus one, Fido won’t release an update for it because their current software version is incompatible with what’s on your phone. If you want to check for updates, try inserting a Telus SIM card on it and see if you can install updates that way.

Secondly, even if your phone has been unlocked, it doesn’t’ always mean that all features will work with another network. Make sure that you check with Fido why some functionalities you mention here are not working. It’s possible that the software running on the device, which is from Telus, does not work when the phone is connected to another network.

Problem #8: Galaxy S5 overheating after it got hardware damaged

Hey Thedroidguy!

I have a Samsung S5. I placed it in my back pocket and somehow it got hardware damage. The SD card slot had been bent and the damage is visible in the back cover. The damage is visible in the top right part of the SD card slot (middle of the phone) though there is no damage to the front of the phone or the screen.

When this happened, the phone started heating up alot. I didn’t think it was much of an issue though while it was heated up the phone didn’t turn on. So I thought it was just dead. I noticed that most of the heat comes from the middle part of the phone right under where the bent part is.

I have removed the SD card using screwdrivers to pry it out (though the SD card slot didn’t take any further damage). I have tried to remove the battery and reinsert it, try a different charger, also try a different battery. I tried to charge it for 20 minutes but that only caused it to heat up.

Also, I have done the hold the power button for a minute to discharge the RAM but that didn’t work. I have taken out the SD card and the SIM card.

I hope you guys can help me. Thank you for taking the time to read this letter. Sincerely. — Arthur

Solution: Hi Arthur. Hardware damage, whether due to accidental drop, water exposure, or heat, can cause serious problems. Oftentimes, damage to the motherboard and other parts are permanent so you can’t hope for some software magic tricks to fix it. If the overheating issue started right after you removed your phone from your pocket, it’s possible that other components in the motherboard may also be damaged at this time. The best course of action that you can take is to have the phone checked by Samsung or an independent service center so the extent of the damage can be assessed. Our blog does not provide hardware troubleshooting and solutions so if you are intent on checking the hardware yourself, try to look for other websites that can give you what you need.

If you have already tried some troubleshooting steps before emailing us, make sure to mention them so we can skip them in our answers.


Problem #1: Galaxy Note 4 stopped booting up after installing Marshmallow update

It all began after a Marshmallow update in November 2016. The phone was quick, snappy, and with 4 large Krait 2.7GHz cores and plenty of RAM and an Adreno 420, it arguably should have the hardware to run anything an S7 can run. Yet, barely received Marshmallow before Nexus 6’s were already on 7.1.1.

Meanwhile, Samsung had pulled everyone to attempt a Note 7 salvage and then a Note 7 recall, a push to get its VR Gear ready and out from Christmas. Meanwhile they have side issues like smart appliance problems and to save face they devote the only energies left to trying to at least get ONE phone (S7) on Nougat (still not happened as of Jan 10th 2017).

At the same time a minor update or two gets pushed to Note 4s, none updating to anything beyond 6.0.1 and more importantly not fixing the “crash machine” that turned a perfectly working Note 4 into after Marshmallow. We are talking clear cache, full factory resets, new batteries, new SIM cards, pulling SD cards, nothing but pulling battery and praying it will restart. THEN suddenly I read a blog and a girl points out if you run a music player in the background, it will never crash. Guess what? Absolutely right! Run Pandora (need to leave volume on at least 1 or it will pause, closing background running, so leave it on low volume and you could open up 100 apps and runs 10 videos and it would FLY like nothing was ever wrong? Unfortunately you can’t take a call without killing the player and that spells the ends and crash city all over again. Finally, two days from our Pixel XL delivery, the Note 4 now is total blackout, no response to changing, new batteries. Zero signs of life. An attempt to plug into my Mac recognized nothing. I’m about to get out the PC we have (Yoga 2 Pro i7) and see if it can see anything, but there are no signs of life and initial attempts to drain battery from RAM yielded nothing. But it seems our only hope? Can you even FLASH a phone when it shows no response to power or does not recognize by a laptop?

After that, background music player workout I feel it’s 100% software somehow, even if it lay in power management code. I think Samsung has to know it nearly bricked all Note 4s and is spread so thin it won’t admit these phones need patches STAT! Thoughts? I just want to get mine to power on so I can even get my trade in credit! Heck, the phone specs are so good I shouldn’t even NEED a new phone? Am I right on any of this? — Kevin

Solution: Hi Kevin. First of all, if the main concern here is on how to power back your Note 4 on, you must try all the usual dose of software troubleshooting steps for this issue. These steps include:

  1. using a different charger,
  2. using a new battery, and
  3. restarting the phone to different boot modes

If you’ve already tried another charger and battery before contacting us, then the only remaining step you need to do is to see if you can boot the phone to other modes. Keep in mind that booting to safe mode is not a solution in itself, but rather a way to possibly do something about the issue. For example, if your phone only boots to Odin or download mode at this time, there’s a chance that you may be able to solve the issue by flashing a stock firmware. Below are the steps on how to boot your phone to different modes:

Boot in Recovery mode:

  • Charge the phone for at least 30 minutes.
  • Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  • When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  • When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  • Using the Volume Down key, navigate through the options and highlight ‘wipe cache partition.’
  • You can either wipe the cache partition or do a factory reset when in this mode.

Boot in Download Mode:

  • Charge the phone for at least 30 minutes.
  • Press and then hold the Home and Volume DOWN keys, then press and hold the Power key.
  • When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume DOWN keys.
  • Wait until the Download screen appears.
  • If you can boot the phone in download mode but not in other modes, that means that your only way out may be to flash a stock or custom firmware.
  • Use Google to look for a guide on how to do it.

Boot in safe mode:

  • Charge the phone for at least 30 minutes.
  • Press and hold the Power button.
  • Once the ‘Samsung Galaxy S7’ logo appears, release the Power key and immediately press and hold the Volume Down button.
  • Continue holding the button until the phone finishes rebooting.
  • Once you see the text “Safe mode” at the bottom left corner of the screen, release the Volume Down button.
  • The only difference of safe mode from normal mode is that the former prevents third party apps from running. If you can boot the phone in safe mode but not in normal mode, uninstall all apps until the issue (that prevents you from booting normally) is eliminated.

In most cases, if you’ll be unable to power a device back on to any of these modes, it usually means that there’s a hardware malfunction involved. In this case, we suggest that you bring the phone to a Samsung service center for repair or replacement.

Secondly, if you think Samsung updates is the sole cause of this disaster, you should contact them directly. We are not Samsung so there’s little to nothing that we can do in terms of resolution. The only way we can be of help is to publish your situation so other users will become aware of this issue. For our part, we really can’t say that it’s Samsung’s fault, especially if the update is coursed through your carrier’s update system. System updates, in general, can be a package of incremental patches from all parties involved (Samsung, your carrier, Google) so there’s no way we can say that’s it’s a purely a Samsung issue.

Problem #2: Galaxy Note 4 red charging light stays on even when battery is taken out | Galaxy Note 4 keeps freezing and randomly rebooting on its own

Hello, I have been having troubles with my Note 4 over the last several days. The persisting problem is that the phone regularly turns off while charging. Even when I remove the charger and the battery, the red charging light still stays on.

There are several other problems such as the phone tends to freeze and shut off at least a couple times daily. It takes numerous tries to restart the phone (taking out the battery and putting it back in), and I also get the “Downloading… Do not turn off target” error message at least once a day. I have also tried the soft reset numerous times but the problems still persist. What do you think might be the best solution to these problems? Note: The phone is currently up to date with the software, there is an 8GB free of storage. After clearing the cache, the same problems persisted and do not have an SD card.  Thank you. —  Anthony

Solution: Hi Anthony. It’s not normal for a phone’s red LED light to stay on even when the battery and/or charger has been disconnected. The LED itself needs a battery source to work in the first place. Either you:

1.) mistakenly identified a dead red LED light as lit,

2.) or that there’s a hardware issue that causes the phone to continue supplying the LED light with power even if the power source has been disconnected.

The second situation is obviously not normal so for this to happen alone, that’s already proof of hardware malfunction. In this case, you should have the phone checked by Samsung so the hardware issue can be correctly diagnosed.

For the freezing and random reboot issues, the cause may be one and the same with the one that causes the LED light to turn on even when the battery is not inserted.

In some cases, bad software may also be to blame so before you consider having the phone repaired, you can try some software hacks first.

Update all apps

The first thing that you want to do is to ensure that all your apps are updated. You want to do this in order to minimize bugs from apps. In order to update all apps at once, simply do the following:

  • Open Google Play Store app.
  • Tap the Menu button.
  • Tap My apps and games.
  • Tap UPDATE ALL.

If you are fond of installing apps from third party sources (outside of Google Play Store), make sure that they are also fully updated and secure. Third party apps from other sources may or may not be compatible with the current Android version on your phone so it’s primary duty to ensure that they are.

Observe the phone in safe mode

In some cases, third party apps can be problematic and can lead to all sorts of problems. If you have plenty of apps installed, it’s possible that one of them may be causing the problem. To check, simply boot the phone to safe mode. While safe mode is on, third party apps and services are prevented from running. Make sure that you observe how the phone behaves for at least 24 hours so you’ll notice the difference. If you’ll notice that the freezing and random reboot issues won’t occur, that’s an indication that one of your apps is to blame. The steps on how to boot your Note 4 to safe mode is provided above.

Keep in mind that safe mode won’t tell you the name of the offending app. You must do trial and error in identifying it.

Wipe the phone clean with factory reset

Factory reset will restore all software settings back to their known, working state, effectively deleting whatever glitch that may have developed after unboxing. Because it reverts the software to its initial clean version, it’s a good way to get rid of any app- and operating system-level bugs. It’s also the ultimate software solution that you can try on your end. Like in safe mode, we recommend that you observe the phone for 24 hours without installing anything to see any difference. If the problem lies on the software, factory reset should fix it. If the problem returns after a factory reset (and without installing apps yet), the cause must only be hardware in nature. In this case, you must have the phone repaired or replaced.

Here are the steps on how to factory reset your Note 4:

  • Turn off the Galaxy Note 4 completely.
  • Press and hold the Volume Up and the Home keys together, then press and hold the Power key.
  • When the Note 4 vibrates, release both the Home and Power keys but continue holding the Volume Up key.
  • When the Android System Recovery shows on the screen, release the Volume Up key.
  • Using the Volume Down key, highlight ‘wipe data / factory reset’ and press the Power key to select it.
  • Now highlight ‘Yes — delete all user data’ using the Volume Down key and press the Power key to begin the reset.
  • When the master reset is complete, highlight ‘Reboot system now’ and hit the Power key.
  • The Note 4 will restart but it will be longer than usual. When it reaches the Home screen, then begin your setup.

Problem #3: Galaxy Note 4 keeps rebooting on its own

My device has been operating just as usually until one day, when I was on the internet, it powered off on its own while it still has plenty of battery. Later, it powered on on its own, but before I could touch the screen, it turned off again. This continued for hours. I tried removing the battery and waited for a few minutes before placing it back. However, once the battery is placed, the process starts again and again. I left it there for around half a day. When i went to check on it, the screen was on and it stopped power off-ing. I thought it was okay, but the next few days, i noticed that whenever I press the sound button, it powers off, then on again. Each time it powers off and on, the screen will show a setting about my SD card. Some settings will also be reset, example, the percentage showing beside the battery will disappear. The sound also automatically turns to the loudest. I only had this phone for about one and a half year. I would appreciate a solution. Thank you. — Eco

Solution: Hi Eco. Like what we tell Anthony above, this issue can be caused by a bad hardware or by a software glitch. So, if you haven’t tried any software troubleshooting at this point, we suggest that you do them first. Start by wiping the cache partition. Sometimes, system updates or app installations can corrupt the system cache. In order to tell the phone to build a new cache, you must first wipe the cache partition, where the system cache is stored. Here’s how to do that:

  • Turn off the Galaxy Note 4 completely.
  • Press and hold the Volume Up and the Home keys together, then press and hold the Power key.
  • When the Note 4 vibrates, release both the Home and Power keys but continue holding the Volume Up key.
  • When the Android System Recovery shows on the screen, release the Volume Up key.
  • Using the Volume Down key, highlight the option ‘wipe cache partition’ and press the Power key to select it.
  • When the wiping of the cache partition is finished, highlight ‘Reboot system now’ and hit the power key.

If wiping the cache partition won’t make any difference, follow the rest of the software troubleshooting we provide to Anthony above.

Should the issue remains after a factory reset, the next best thing to try is to get another battery, preferably an original Samsung one. There’s a chance that the battery may have simply lost significant capacity to hold a charge, causing the phone to randomly lose power.

If that won’t work either, some other motherboard issue may be to blame. Have the phone repaired or replaced.

Problem #4: Galaxy Note 4 charging erratically | Galaxy Note 4 not charging properly

Samsung Note 4 phone was having problems not charging. Bought a new cord, it worked again, for a few weeks and went back to what it was doing, not charging. I then proceeded to buy a new battery, new fast charge and cord, this has worked for a few weeks and it’s back to the same problem again. It’s starting to get frustrating. What is the actual problem and why does it keep doing this?

I have tried many things, example, old battery with new fast charge and cord, nothing. New battery with the old fast charge and new cord, again, nothing. It won’t charge. If I finally get it, it charges for a few seconds or take hours to charge. This is unfair as the phone is only a year old. I had a HTC that lasted 3 years until the screen was completely cracked and was out dated. So I upgraded and have been having this problem with the charge for months now. I’ve never had a problem like this before with any other phone. I need this phone for work. — Ashkatt13

Solution: Hi Ashkatt13. The issue here is not about unfairness but most probably about how you take care of your phone. There’s high likelihood that the problem is phone-related. Most of the time, charging issues start to appear if a user is not careful when plugging or unplugging a charging cable to the charging port. The charging port can get damaged if one of the pins inside gets damaged if one is not careful with the charging cable. Moving the cable from side to side while it’s inserted to the port is one of the most common cause of charging problems. Try checking the inside of the port using a magnifying tool to see the condition of the pins. Sometimes, dust or dirt can find their way into the port as well so you also want to clean the charging port if you can. The best thing to do though is to let a professional do the checking and cleaning for you, especially if you suspect that one of the pins may had been bent.

Problem #5: Galaxy Note 4 slow performance issue | Galaxy Note 4 works very slow

My phone was running slowly and in general acting like it didn’t have enough RAM. It would also restart frequently, often when multiple apps were running at the same time. To fix this, I had planned to do a data wipe/factory reset and reinstall the custom ROM I had, which up until two weeks ago was working fine. The process did not go smoothly. All data was wiped from the phone, including the OS. The phone will boot into download or recovery mode, but every OS I have tried to install would not take. It has bootlooped, bricked, or had kernel panic every time. All the important data is backed up, but at this point it isn’t even a phone. I have the most recent Team Win custom recovery loaded on the phone, but the backup I thought I had is no longer there. What can I do to make sure a new OS installs correctly? At this point it is effectively a car frame without an engine or transmission. — Justin

Solution: Hi Justin. As long as you follow a developer’s exact instructions on how to flash a custom ROM, there shouldn’t be any problem. The usual cause of boot loop after flashing is mainly due to incorrect firmware usage. Keep in mind that that not every firmware is compatible with every phone model. Make sure that you’re using the correct one every time you flash. Do some research about the software first to see if other users have reported problems with it in the past.

We assume that you are aware of the risks of flashing custom software so you must accept whatever happens to your phone since you’ve decided to stay away from official software in the first place. The general rule if you encounter problems after flashing is to contact the developer of the software. Asking us, third party technicians, for solutions after flashing won’t help at all. There are thousands of custom software out there (that’s how interesting Android community is) so that makes it very challenging for even seasoned Android troubleshooters to really know the cause of a particular problem brought about by a certain software. The best that you can do is to contact the developer of the software, or engage other Android users who may have tried the said software before.

The only suggestion we can give you is to bring everything back to stock. Unroot the phone and install the original stock firmware  (probably Lollipop) and see how the phone performs. If the issue persists after unrooting and flashing, the problem shouldn’t be software. Consider having the phone replaced if you can’t bear the slow performance issue.

Problem #6: Galaxy Note 4 won’t restart

My Note 4 “will not restart.” The problem is simple — when I hold the power button and press restart, the phone will power off normally and the moment the screen goes black, the phone will freeze. I will either have to remove the battery or hold down the power and volume down button for the phone to turn on again. This is not a problem until you have to perform a software update, it renders the phone useless as the device wouldn’t restart when the phone requires itself to. The same happens if the phone is off and it’s plugged in for charging. The screen goes blank when I try to turn it on. I’ve already tried a factory reset, Kies (initialized it), Odin (flashed a new firmware), etc., but nothing has worked. Any help will be appreciated Regards. — Ahmed

Solution: Hi Ahmed. There’s no more software hack that we can think for this issue. If flashing a new firmware and factory reset did not fix the issue, there may be an unknown glitch that causes the phone to behave this way. Consider getting a replacement phone should the problem remain.

Problem #1: Galaxy Note 4 screen turns black when not in use | Galaxy Note 4 overheating issue

Hello sir. I have a Samsung Note 4 edge. My phone went black screen when i stop using it but when i am using the phone it works fine until i stop using it. i have to remove battery and put it again and press the power button. It goes into download mode (Odin mode) while charging. When i use it, it works fine but when i keep the phone it goes black. And my phone gets really hot while it is black screen. I did factory reset. I changed firmware. Still the same. Please help me. — Fawad

Solution: Hi Fawad. Factory reset and flashing (installing stock or custom firmware) are two of the most effective solutions for any software issue. If nothing positive happens after doing them, you can assume that the problem may be hardware related. The screen assembly may be malfunctioning or that other components are not working properly causing the screen to stay black and the phone to overheat. Taken together, these symptoms are not caused by any software glitch we know of so we recommend that you send the phone in so its hardware can be checked for errors.

Out of warranty repair is not free so sending your phone to Samsung will cost you something so be ready to shoulder the fee if needed.

Problem #2: Galaxy Note 4 slow performance issue | Galaxy Note 4 reboots when playing video or loading photos

Have already executed these options a) a factory reset. b) removed the memory card. c) Have formatted the memory card. d) Have used another memory card. e) Have change the SIM card from service provided. f) Have uninstalled all apps.

Since the last 2 months, my phone performance has been a laggard. While selecting any icon, or during the process, it takes 3-5 seconds to activate the process. At times, the screen blanks out for 3-5 seconds with the top header visible.

At times, while watching a video or while selecting an image from picture library, it would suddenly blank out, with a sound of vibrate (twice) it would reboot the system (a typical process every time it reboots. It feels that it almost is out of memory to handle and reboots the system. Even now at times when I receive the call, the screen blanks out for 2-3 seconds and then comes on to select the option to talk. The problem still persist. I do not wish to sell it off because of this issue. Kindly guide. — Rajen

Solution: Hi Rajen. If factory reset and uninstallation of all third party apps did not fix the issue, the problem must be one of the following:

  • an operating system glitch
  • a defective battery
  • other unknown hardware malfunction

Flash a stock firmware. Whether your phone is rooted or not, running stock or custom firmware, we recommend that you flash a new stock ROM to it to see if that will help. If you haven’t heard of flashing before, your phone is probably running an official firmware so try to do some digging on how to flash (or install) an official firmware to it like an older version of Android. For example, if your phone is now running Android Marshmallow, try to manually flash older Android to it like Lollipop to see if it will help improve the phone’s general performance. The exact steps on how to flash a firmware is beyond the capability of this post so if you have no clue on what to do, make sure to do some basic research about the topic first. Flashing a firmware can potentially brick a phone so make sure to do the steps correctly.

Try using a new Samsung battery. Many users of older Galaxy flagship phones encounter performance problems due to erratic battery. If your phone is still using the original battery at this time, this part may be in dire need of replacement at this point. Lithium-ion batteries like the one in your phone can significantly lose capacity after using them day in and day out for over a year. Even if you take care of your device, the battery will simply degrade on its own after some time. We’ve seen a lot of cases wherein a bad battery indirectly causes a device to slow down, freeze, or slow down in terms of performance so it’s worth checking at this time. If you have another Note 4 or can borrow a different one from a friend, try using its battery on the first one and compare the performance. Otherwise, simply buy a new one to see if that will fix the issue or not.

Have the phone repaired or replaced. If the two suggestions won’t work in this case, there may a deeper cause to the problem that we don’t know of. A Galaxy Note 4 is consists of hundreds of different parts and they are all expected to work in a chain of activities. If there’s a break in this chain, the entire unit may stop working properly or at all. For example, if there’s a bad transistor in the phone’s processor, such bad component may cause an incorrect timing effect on other transistors, which can do down the entire chain manifesting as a freezing, lagging, or slow performance problem. The same is true for other parts. Sometimes, a technician may not be able to fully identify the cause of the problem at all so he/she may simply declare it as a motherboard issue, which means that the problem is not fixable. In this case, you’ll be advised to simply have the phone replaced.

We don’t know the full history of the device so we can’t even begin to tell you what may be wrong with the hardware. If possible, try to send the phone in to Samsung first so a certified technician can check the hardware. If that’s not possible, consider sending the phone to a third party service center.

Problem #3: Galaxy Note 4 stuck in Samsung logo screen

Verizon stock version of Samsung Note 4 is stuck on logo screen. Happened out of the blue. Today changed from Verizon to T-Mobile in process. Bricked by Verizon?

It is 1 week to the day since dropping Verizon. Left with phone working on Wi-Fi this morning. By the time I returned home 1.5 hours later, I looked on phone to see start screen halt. Tried pulling battery & reinsert plus boot…still bricked on splash Samsung screen. Removed battery, and tried soft boot. Failed. Followed with battery out & drain process followed by cache wipe with SIM in & SIM out, dead &dead.

Attempted cache wipe & restart again, no change. Safe mode shows e: failed to mount /cache no file or directory. E: Can’t mount cache/recovery/last recovery E: Failed to mount /data E: Cannot mount /data/log/recovery log E: Failed to mount /system.

There is more but you get the picture. I am dejected…T-Mobile screwed up massively setting up 2 phones (mine & wife’s) & I never got my texts/contacts/data etc transferred between old & new phone. I have years of business info on the note 4 & desperately need it. — Csminion

Solution: Hi Csminion. As far as software troubleshooting is concerned, your only option at this time is to see if your phone will restart to other modes. If it does, that’s the only time that you can do a specific follow up troubleshooting. For example, if you can manage to boot the phone to recovery mode, you may be able to fix the problem by wiping the cache partition or by factory resetting it. If the phone remains stuck in Samsung logo screen and won’t get you nowhere, something must have damaged the bootloader causing the device to pause and unable to do the complete boot up process. In this case, like in the cases above, you should find a way to have the phone repaired or replaced.

For reference, below are the exact steps on how to restart a phone to a specific boot mode and how best to solve your issue afterwards:

Boot in Recovery mode:

  1. Charge the phone for at least 30 minutes.
  2. Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  3. When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  4. When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  5. Using the Volume Down key, navigate through the options and highlight ‘wipe cache partition.’
  6. You can either wipe the cache partition or do a factory reset when in this mode.

Boot in Download Mode:

  1. Charge the phone for at least 30 minutes.
  2. Press and then hold the Home and Volume DOWN keys, then press and hold the Power key.
  3. When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume DOWN keys.
  4. Wait until the Download screen appears.
  5. If you can boot the phone in download mode but not in other modes, that means that your only way out may be to flash a stock or custom firmware.
  6. Use Google to look for a guide on how to do it.

Boot in safe mode:

  1. Charge the phone for at least 30 minutes.
  2. Press and hold the Power button.
  3. Once the ‘Samsung Galaxy S7’ logo appears, release the Power key and immediately press and hold the Volume Down button.
  4. Continue holding the button until the phone finishes rebooting.
  5. Once you see the text “Safe mode” at the bottom left corner of the screen, release the Volume Down button.
  6. The only difference of safe mode from normal mode is that the former prevents third party apps from running. If you can boot the phone in safe mode but not in normal mode, uninstall all apps until the issue (that prevents you from booting normally) is eliminated.

Problem #4: Solutions to Galaxy Note 4 SMS problem

I just signed up for T-Mobile prepaid Family Talk Plan. I know this is old news since the Note 4 is ancient, but if I can avoid buying a new phone right now, that would be great.

My data works, just not my text messaging service. I believe I do not have the right call center number but can not get your workaround to work on my phone. Can you help me out? I have no other way to find it via settings, or I am missing where it is located. To change the message center number of your phone go to the dialer and enter *#*#4636#*#*. If all goes well you should be brought to a hidden menu setting on your phone. Select phone then scroll all the way down to SMSC. Make sure to change this to the number T-Mobile is using which is +12063130004. You can also access this message center number from the messaging settings of your phone. — Kaydevmom

Solution: Hi Kaydevmom. One of the symptoms of an incorrect message center number issue is being unable to send SMS and MMS. If this is your problem or whatever your SMS problem is, we recommend that you contact your carrier first so they can walk you through the entire troubleshooting procedures for this issue. You also need to ensure that you have the correct Message center number from them and not from any unverified third party sources from the web.

Most SMS and MMS issues are caused by network problems so third party technicians like us are of not much help. Unless you tend to modify SMS and network settings all the time, SMS and MMS problems are mostly due to service interruptions that are beyond an average user to fix.

Some messaging apps may interfere with the default messaging apps in a phone sometimes so if you installed another messaging app, you can try to observe the phone to safe mode as well. Safe mode prevents third party and services so if you’ll be able to text normally, that’s proof that one of the apps is the culprit. To boot in safe mode, follow these steps:

  1. Press and hold the Power button.
  2. Once the ‘Samsung Galaxy S7’ logo appears, release the Power key and immediately press and hold the Volume Down button.
  3. Continue holding the button until the phone finishes rebooting.
  4. Once you see the text “Safe mode” at the bottom left corner of the screen, release the Volume Down button.
  5. The only difference of safe mode from normal mode is that the former prevents third party apps from running. If you can boot the phone in safe mode but not in normal mode, uninstall all apps until the issue (that prevents you from booting normally) is eliminated.

As far as changing of the message center number goes, here’s how it’s usually done:

  1. Open the Messages app.
  2. In the message list, press Menu.
  3. Tap Settings.
  4. Tap Message Center
  5. Enter the correct Message Center number.
  6. Press OK

In phones running Marshmallow and Nougat, there’s a slightly different way to do it. Below are the steps you have to take:

  1. Open the Messages app.
  2. Tap the Menu icon (three-dot icon on the top right side).
  3. Tap Settings.
  4. Tap More settings.
  5. Tap Text messages.
  6. Tap Message center number field to edit.
  7. Tap Set to confirm change.

If your problem continues after booting to safe mood, uninstalling apps, or with a new Message Center number, you can also try to wipe the messaging app’s cache and data. Here’s how:

  1. Open the Settings menu either through your notification shade (drop-down) or through the Settings app in your app drawer.
  2. Navigate down to “Apps”. This may be renamed to something like Applications or Application Manager in OEM skinned versions of Android 6.0.
  3. Once in there, click on an application.
  4. You’ll now see a list of stuff that gives you information about the app, including Storage, Permissions, Memory Use, and more. These are all clickable items. You’ll want to click on Storage.
  5. You should now clearly see the Clear Data and Clear Cache buttons for the application.

Problem #5: Galaxy Note 4 mobile data won’t work after using Bluetooth

My Samsung Galaxy Note 4 is able to access the internet using wifi and cell network. However after using Bluetooth, I cannot access the internet or email via cell network (Koodoo) but text works and voice calls work as well as accessing the internet using WiFi. I have tried removing the battery to reset, that did not work. I have also tried to turn off network access then back on and that does not work. I have checked the APN settings and all are correct. After hours or days it somehow gets reset and starts working again (until I use Bluetooth and the problems reoccurs).

When accessing the internet I get a “Cannot find proxy server error). I suspect that I have to reset something after using Bluetooth but I do not know what it is. — Grant

Solution: Hi Grant. Try doing a safe mode first to see if a third party app or service is interfering with the Bluetooth or mobile data functionalities of the phone. If you can’t replicate the issue while the phone is in safe mode, you can assume that one of the apps is problematic. Try to uninstall apps you installed recently or any app that may use Bluetooth or mobile data in order to work. If you can’t isolate the bad app, consider uninstalling all third party apps until the issue is eliminated.

However, if the problem remains even when the phone is in safe mode, we recommend that you do a factory reset if you think something has been misconfigured. Make sure to create a backup of important files before doing this type of reset.

To factory reset your Note 4, follow these steps:

  1. Turn off the Galaxy Note 4 completely.
  2. Press and hold the Volume Up and the Home keys together, then press and hold the Power key.
  3. When the Note 4 vibrates, release both the Home and Power keys but continue holding the Volume Up key.
  4. When the Android System Recovery shows on the screen, release the Vol Up key.
  5. Using the Volume Down key, highlight ‘wipe data / factory reset’ and press the Power key to select it.
  6. Now highlight ‘Yes — delete all user data’ using the Vol Down key and press the Power key to begin the reset.
  7. When the master reset is complete, highlight ‘Reboot system now’ and hit the Power key.
  8. The Note 4 will restart but it will be longer than usual. When it reaches the Home screen, then begin your setup.

Problem #6: Galaxy Note 4 camera error when switching from rear to front camera

Front camera server error when I open camera and when I switch from rear to front camera. I’ve reset my phone on airplane mode and it works shortly after that on occasion.

I also reset the cache partition and no luck. I even cleared the data and camera cache. I’m having a hard time figuring out the issue and it started only recently when I downloaded Snapchat. I uninstalled the app and nothing has changed. Hopefully you can help me, I’m looking forward to hearing from you thanks! — Astrid

Solution: Hi Astrid. Like Grant above, we suggest that you try observing the phone in safe mode first. If that won’t help, you can then proceed to doing a more drastic step of factory reset. This will help you determine if one of the cameras is defective, or if there’s just an operating system glitch causing the trouble. Make sure to test the cameras’ functionality right after a factory reset, when you haven’t installed any app or updates yet. If the problem continues, one of the cameras must not be working properly.

Problem #1: Galaxy Note 4 wifi keeps disconnecting

I have a problem with my Note 4 Wi-Fi. It works fine after a hard reset, and sometimes, though not always after a soft reset. This only lasts until I let the phone go to sleep however, as the Wi-Fi will then turn itself off. I have tried hard resetting through the menu, through holding the volume, power, and home buttons simultaneously, and through initializing the device again through Samsung Smart Switch. I have also sent it to the vendor, who hard reset it, saw the Wi-Fi working immediately afterwards and sent it back claiming nothing was wrong.

The issue here is that after the Wi-Fi turns itself off, it is almost impossible to turn back on again. I hit the switch, and it turns gray for several minutes before turning back to the off position. Sometimes, it will turn on, but then it will claim the local network is out of range, or it will have trouble connecting to it. In the case that it does connect, then it frequently drops the connection.

In addition to the resets, I have also tried safe mode and clearing cache. Neither have worked.

Is this a software problem as suggested by one phone repair center, and if so, is there anything else I can do? Or is it a hardware problem as suggested by another, and should I be looking at a new Wi-Fi Antenna?

I have an international Note 4 (Model SM-N910C) that I am using on Ting, which uses the T-Mobile network. Since November, my Wi-Fi has not worked properly. After a long time turned off, or after a factory reset, the Wi-Fi will function mostly normal, but as soon as the phone goes to sleep, it will turn off. When I try to turn the Wi-Fi back on again, it will grey out the switch for several minutes before settling in the off position. In the case that I do finally get the Wi-Fi to turn on, it will have trouble connecting, either claiming that the network is out of range, or just saved, but not actually doing anything to connect. After telling it to connect several times, it will finally connect, but then randomly disconnect and reconnect for as long as I am using it provided I don’t let it sleep again, in which case it will turn off and the whole problem starts over. I have done hard resets, both through the Android menu and through the boot menu access by pressing home/power/volume up. I have also flashed the software again through Samsung Smart Switch. Despite all of this, the problem persists. Do you have any idea what could be causing this? Thank you Regards.  — Michael

Solution: Hi Michael. The problem is most probably a bad wifi antenna more than a software one. As far as software troubleshooting is concerned, you’ve already all the things anyone can do in this case. That factory reset did not fix the issue is a strong indication the problem is beyond an average user to fix, if it’s fixable at all. Wifi functionality uses a special chip in order to work. This chip has its own firmware that’s independent of the operating system. The factory reset that you did addressed possible operating system issue but not the possible problem with the wifi chip or its firmware. Unfortunately, there’s no way to check the true status of the wifi chip firmware so even a good technician is only limited to replacing this particular chip, if an available replacement component can be purchased.

Problem #2: Galaxy Note 4 no audio when playing music or video via bluetooth

A few days ago, while I was driving and listening to a video, my device abruptly stopped playing media audio through bluetooth connections. Call audio still works, but videos and music will simply run silently. This problem occurs on both my bluetooth devices, each made by a different manufacturer, so I know it’s a problem with my phone. Both devices are set up to play media audio and both have worked fine previously. I have tried unpairing and repairing as well as resetting my phone. I would appreciate any advice you could offer. P.s. I am not actually certain what android os I am running, but I’m reasonably certain it’s the latest one since I update whenever it is offered. — A.anderson.785

Solution: Hi A.anderson.785. Sometimes, a corrupted system cache can cause other apps or functionalities to work erratically. To make sure that the system cache is up-to-date all the time, you must regularly clear the cache partition. Wiping the cache partition is an important maintenance procedure so it can be performed whether you’re experiencing an issue or not. Here’s how to do it:

  • Turn off the Galaxy Note 4 completely.
  • Press and hold the Volume Up and the Home keys together, then press and hold the Power key.
  • When the Note 4 vibrates, release both the Home and Power keys but continue holding the Volume Up key.
  • When the Android System Recovery shows on the screen, release the Volume Up key.
  • Using the Volume Down key, highlight the option ‘wipe cache partition’ and press the Power key to select it.
  • When the wiping of the cache partition is finished, highlight ‘Reboot system now’ and hit the power key.

Boot to safe mode

If refreshing the system cache won’t help, try to check if an installed third party app is interrupting the bluetooth functionality. You can do that by restarting the phone in safe mode and observing the phone. If bluetooth functionality will work normally in safe mode, that’s a sign that one of the third party apps is to blame. To boot your phone to safe mode, follow these steps:

  • Turn off the phone completely.
  • Press and hold the Power key and the Volume Down key.
  • When the phone starts to boot, release the Power key but continue holding the Volume Down key until the phone finished restarting.
  • Safe mode will be display at the lower left corner; you may release the Volume Down key now.

Install updates

We also highly recommend that you install any app or system updates that you have hold off. Try checking the settings of the Google Play Store app and make sure that you set it to auto-update all the time. Otherwise, simply install app updates manually more often.

The same should be true when it comes to system updates. Make sure that you install whatever system updates there is. Updates are released for a reason and sometimes they contain fixes to known bugs.

Wipe the phone clean via factory reset

If all else fails, don’t hesitate to reset all software settings to their defaults by doing a factory reset. This procedure will delete all user data such as photos, videos, contacts, etc., so make sure that you create a backup before doing it.

Below are the steps on how to factory reset your Note 4:

  • Turn off the Galaxy Note 4 completely.
  • Press and hold the Volume Up and the Home keys together, then press and hold the Power key.
  • When the Note 4 vibrates, release both the Home and Power keys but continue holding the Volume Up key.
  • When the Android System Recovery shows on the screen, release the Volume Up key.
  • Using the Volume Down key, highlight ‘wipe data / factory reset’ and press the Power key to select it.
  • Now highlight ‘Yes — delete all user data’ using the Volume Down key and press the Power key to begin the reset.
  • When the master reset is complete, highlight ‘Reboot system now’ and hit the Power key.
  • The Note 4 will restart but it will be longer than usual. When it reaches the Home screen, then begin your setup

Problem #3: Galaxy Note 4 slow performance, freezing, randomly rebooting issues

My Note 4 started freezing 4 days ago. First it was like a lag then progressed to freezing, then freezing and restarting. The phone has popped up with errors saying various apps won’t load. System apps, apps that came on the phone. I have tried soft reboot, hard reboot, and even a factory reset. Now the phone won’t reboot at all. I now get a totally black screen with a menu on it such as reboot, loading something from my SD card, to name a couple of them. I have no idea what happened. I have not deleted anything off my phone except apps I have downloaded to my phone. —  Nicole

Solution: Hi Nicole. Try to restart the phone to different boot modes and see if you can do a follow up troubleshooting for each one. Below are the exact steps on how to do each one:

Boot in Recovery mode:

  • Charge the phone for at least 30 minutes.
  • Press and then hold the Home and Volume UP keys, then press and hold the Power key.
  • When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume Up keys.
  • When the Android logo shows, you may release both keys and leave the phone be for about 30 to 60 seconds.
  • Using the Volume Down key, navigate through the options and highlight ‘wipe cache partition.’
  • You can either wipe the cache partition or do a factory reset when in this mode.

Boot in Download Mode:

  • Charge the phone for at least 30 minutes.
  • Press and then hold the Home and Volume DOWN keys, then press and hold the Power key.
  • When the Samsung Galaxy S7 shows on the screen, release the Power key but continue holding the Home and Volume DOWN keys.
  • Wait until the Download screen appears.
  • If you can boot the phone in download mode but not in other modes, that means that your only way out may be to flash a stock or custom firmware.
  • Use Google to look for a guide on how to do it.

Boot in safe mode:

  • Charge the phone for at least 30 minutes.
  • Press and hold the Power button.
  • Once the ‘Samsung Galaxy S7’ logo appears, release the Power key and immediately press and hold the Volume Down button.
  • Continue holding the button until the phone finishes rebooting.
  • Once you see the text “Safe mode” at the bottom left corner of the screen, release the Volume Down button.
  • The only difference of safe mode from normal mode is that the former prevents third party apps from running. If you can boot the phone in safe mode but not in normal mode, uninstall all apps until the issue (that prevents you from booting normally) is eliminated.

NOTE: If your phone continues to reboot randomly or fail to boot normally at all after doing all the steps above, you should consider sending it in for repair or replacement.

Problem #4: How to fix Note 4 the keeps restarting on its own

My phone keeps rebooting randomly out of nowhere when I’m not using my phone. This problem started happening a lot after the update to the latest Android version. It’s driving me crazy having to constantly re-inputting my password after it finish rebooting. Can anyone please find out what is causing my phone to just randomly reboot without letting me know why it needs to be reboot?  Or what is causing it to reboot while it’s just sitting there with no apps running in the background. I’ve always check and kill any apps that is running in the background to keep my phone battery from draining. — Ben_jamin1084

Solution: Hi Ben_jamin1084. Random reboot issue can be due to either software or hardware issues so you must try to narrow down possible causes first. The general direction should be to start with software troubleshooting. If nothing changes after you’ve exhausted all software troubleshooting, you can assume that bad hardware must be to blame.

There’s no special set of software troubleshooting for this issue but you can try the ones we suggest for A.anderson.785 above. Basically, what you want to do includes:

  • wiping the cache partition
  • observing in safe mode
  • installing app and system updates, and
  • factory reset

If these software procedures won’t help, try recalibrating the battery by doing the following steps:

Use the phone by playing games or doing tasks to hasten power discharge, until the phone turns itself off.

  • Turn the phone on again and let it turn itself off.
  • Charge the phone without turning it back on.
  • Wait until the battery says it fully charged to 100%
  • Unplug the charger and turn the phone on.
  • If the phone says it’s not 100% anymore, turn it off, plug the charger back in and wait until 100% charge is reached.
  • Unplug the charger the turn the phone on again.
  • Use the phone until you drain the battery down to 0.
  • Repeat the cycle once.

If nothing improves still, get a new battery to see if the old one is causing the trouble.

Finally, if a new battery won’t change the situation at all, have the phone repaired or replaced.

Problem #5: Galaxy Note 4 keeps cannot send calls or SMS | Galaxy Note 4 keeps losing cellular service

Hi. I have Galaxy Note 4, using Optus network in Australia. I have no idea what Android Version it is (I have never heard of Lollipop, KitKat, Jellybean, etc – sounds like stuff to give you diabetes). I can receive calls & SMS & data but I can’t send calls or SMS. When I try it shows “Not Registered on Network”.

Also says “No Service” BUT it shows 3 to 4 bars of reception. It has been like this for a week however it is intermittent. Sometimes I can get “Service” but only for a very short time & when this happens all works OK. I have turned the Flight Mode on & off & it seems to wake it up for a very short time but then shows “No Service” & “Not Registered on Network” again.

The service provider & Optus both say there is nothing wrong at their end. Could I have a virus? Do viruses cause this sort of problem? If so, how can I fix it? Please say you can help as I am going “round the twist” !!! Thanks, Kevin. — Kevin

Solution: Hi Kevin. Both issues must be related or triggered by the same cause so our suggestion for you is to try the basic software troubleshooting above — wiping the cache partition, wiping the cache partition, observing in safe mode, installing app and system updates, and factory reset. All of these procedures are aimed at fixing problems on your phone so if they won’t work, the cause must be coming from the side of your wireless carrier. Make sure that you talk to them for a solution.

Problem #6: Galaxy Note 4 bootloader is corrupted

Hello. My Samsung Galaxy Note 4 has a screen saying “Device memory damaged. The data partition has been corrupted. You need to reset your device to factory defaults. This will erase all your data. (reset device button).”

I have tried soft reset, clicking the reset device button (which does nothing… literally nothing happens), and doing a factory reset (volume up + home + power) but the Android logo never pops up. It simply cycles through the Samsung screen, then the Samsung Galaxy Note 4 screen. I’m not 100% sure whether my Android version is Marshmallow or Lollipop. Any advice and tips would be really appreciated. Regards. — Brian

Solution: Hi Brian. It’s not normal for a functioning Note 4 to be unable to boot to Recovery mode (volume up + home + power). Losing this ability means that the phone’s bootloader may have been corrupted for some reason, causing the phone to be unable to boot beyond the Samsung logo screen. A corrupted bootloader, unfortunately, means that the issue is beyond an average user’s ability to fix as it entails a bad motherboard. If the phone is still within the warranty period, send it in so it can be repaired or replaced.

Problem #7: Unable to install system update for Galaxy Note 4

I originally purchased my Samsung Galaxy Note 4 from T-Mobile in 2014. I eventually switched to MetroPCS in an effort to save some money. I have been unable to update my software from the 4.4.4 version. For the longest time, it would say up-to-date. Then, the other day I got excited when it said update available so I clicked to do the update, and it seemed to go through all the steps only to still have the same version and patch level as before I attempted the update! The following is all the device information: Model Number: SGH-M919 Android Version: 4.4.4 Android security patch level: 2015-11-01 Security Software version: MDF v1.0 Release 3, VPN v1.4 Release 2, ASKS v1.2_161011.

Please help if you can. I really do not want to have to buy a new phone.

It’s also been starting to do wonky things like text messages lagging (I’ve tried many of your fixes with no change). Prior to this, I had a G2 for 4 years with NO problems! Thank you. — Luba

Solution: Hi Luba. You can’t expect to download and install an OTA (over-the-air) update if you are no longer using the network of the original wireless carrier the phone is built for. If you really want to install the latest update for this model, you must do so manually via Odin mode. Flashing, the other term for installing, can be a tricky procedure for a beginner and requires some advance research so make sure to use Google to find a good guide how to do it. Make sure that you also flash the correct firmware. Not doing so can brick the phone.  Keep in mind that flashing modifies core system files, and if not done correctly, may result to making your device an expensive paperweight.

For your text message issue, try wiping the cache and data of the messaging app by doing the following steps:

  • Open the Settings menu either through your notification shade (drop-down) or through the Settings app in your app drawer.
  • Navigate down to “Apps”. This may be renamed to something like Applications or Application Manager in OEM skinned versions of Android 6.0.
  • Once in there, click on an application.
  • You’ll now see a list of stuff that gives you information about the app, including Storage, Permissions, Memory Use, and more. These are all clickable items. You’ll want to click on Storage.
  • You should now clearly see the Clear Data and Clear Cache buttons for the application.

If this won’t, consider wiping the cache partition or do a factory reset.
