Problem #1: Galaxy S5 not charging, only charges when it is off

Hey! I am having charging issues with my Samsung S5. My phone won’t charge while it is turned on. There is no charging symbol (lightning bolt), nor does the LED light blink in red like it usually does when it charges. And it even though I leave my phone alone, it still manages to use up some energy pretty quickly. The only way I can charge my phone is if it is turned off. But even that yields a problem cause while it does charge, it charges on and off every 5 seconds (5 seconds charging, 5 seconds not charging).

I’ve tried cleaning my port, using different cord and troubleshooting. The only thing I haven’t tried is changing the battery and doing a factory reset because my phone is charging pretty slow so I can barely get it to 10% without me maybe leaving to charge overnight. I’d really appreciate the help. Thanks. — Enrilelucy

Solution: Hi Enrilelucy. There’s only so much that you can do to fix this case on your end. There may be a hardware fault causing the erratic charging behavior so you must try another battery or do a factory reset if the rest of the software troubleshooting didn’t help. If using a different battery or factory reset won’t improve the situation either, you should have the phone checked for hardware malfunction. The most likely issue is on the charging port so a thorough diagnostic test must be performed by a technician.

We know that the Galaxy S5 has been around. If you’ve been using your phone for over a year now, there’s a chance that the battery have simply lost significant capacity to hold a charge. Lithium-based batteries gradually degrades the moment they left the factory so replacing it now may help you fix the problem.

If we are not mistaken, the phone’s warranty is already up at this time so consider bringing the phone to an independent service center.

For reference, here are the steps on how to factory reset your S5:

  1. Turn off your Samsung Galaxy S5.
  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.

Problem #2: Galaxy S5 restarts on its own during the evening

My phone keeps randomly restarting and/or freezing several times a day, especially during the evening. The problem has occurred every day for the past month. I have deleted some recent apps added, cleared my cache, changed my battery, even did a factory reset, and still the problem persists. Sometimes, when the phone shuts off it drains the battery completely as well. Occasionally, the battery gets really warm too. I have taken it to a tech several times within the past month but they say they can not find anything wrong with it, even after doing several stress tests on the phone. I know last year it would repeatedly tell me that my SIM card was not detected at various times. I am unsure if that has anything to do with it though since I have not seen that message in recent months. — Chris

Solution: Hi Chris. There are only two possible causes that we can think of — either you’ve installed a problematic app, or that there’s an unknown glitch in the hardware.

To see if a bad third party is to blame, you can either boot the phone to safe mode or do a factory reset. Starting the phone to safe mode blocks all third party apps and services from running so you should observe the phone for at least 24 hours to see the difference. If you think an app is causing this problem, you should uninstall apps until the issue is eliminated. To boot to safe mode, follow these steps:

  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.

Alternatively, you can factory reset and observe the phone for a day as well. You should not install anything — app or update — during the observation period so you’ll know if something that you add later is the cause.

If the phone continues to show the same symptoms either when the phone is in safe mode or immediately after a factory reset, you can assume that bad hardware is behind them.

Problem #3: Galaxy S5 won’t read encrypted SD card

Hi. I have an issue with my SD card for my Samsung S5 SM-G900F. I encrypted the files but one day something happened while the files were encrypting or decrypting and since then the SD card wont mount in the phone. So it’s neither encrypted or decrypted but essentially I can’t access about 6 years worth of photos of my kids which I’m gutted about. I’ve looked into solving this issue online and I understand formatting the SD card would help solve the mount issue but it would also wipe the photos which I want to avoid. I don’t think I’ve backed the files up either. When I either go to encrypt or decrypt the error message I am getting is as follows: ‘Error encrypting SD card. Unable to mount SD card.”

I have tried the SD card in a SD card reader on a PC and also in another phone and the SD card works but the files are encrypted so I can’t access them. If you’ve anything I can try I’d be grateful, many thanks. — Gavin

Solution:  Hi Gavin. SD card encryption is an effective way to keep data from snooping third parties but it has its weaknesses. One of the such limitations is the fact that there’s nothing that you can do if the device that holds the decryption key gets lost or suffers a malfunction. A decryption key for a storage device like your SD card is tied to one device or phone only. If your phone has lost the key or becomes incapable of decryption the card right now, there’s very little to nothing that you can do. There’s no known app or hack that can break Samsung’s decryption system on Galaxy S devices so you’re basically stuck. Even if there’s a software that can do a decryption somewhere (we’re not aware of any at this time), it will still take months for it unlock the card, even when using brute force attack. That’s in fact, the beauty of SD card encryption but it’s also a curse if your situation occurs. If you want to use the SD card again, you can reformat it. Doing so will erase your data but again, there’s just nothing that anyone can do about this situation.

Problem #4: Galaxy S5 Active corrupted files in the SD card

Hello. I have a Galaxy S5 Active. I’ve always had storage issues with the internal storage, but it didn’t inhibit me too much since I knew what was wrong. I have a 64GB SD that I transfer plenty of images to to conserve internal storage. One day, I suddenly had plenty of internal storage, but my files were all there. I was like “oh, okay… suspicious but I’ll take it”. About two days after that, all my SD files were corrupted. They either didn’t load or had the black screen with an exclamation mark. I panicked bad because I CANNOT lose these photos. When I put the SD into the PC, the pictures were seemingly fine… but when I put it in the SD, after constantly force stopping, taking out the battery, restarting… the files are corrupted in my phone. I’m worried and can’t find any resolution. Thank you. — Matthew

Solution: Hi Matthew. The first thing that you must do is to ensure that all your important files are copied to another storage device like a computer. After creating a backup, the next best thing to do is to factory reset the phone to minimize bugs that may be causing the problem. Here’s how to do it:

  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.

Once you’ve factory reset the phone, make sure that you also wipe the SD card clean by reformatting it. If this SD card has been around, we recommend that you don’t use it as your primary backup storage. Use another device where you can keep another copy of your irreplaceable files just in case this SD card will fail again. Keep in mind that any storage device can fail anytime. The older a storage device is, the higher its chance of failing so don’t be lax when it comes to creating backups.

To reformat an SD card in your S5, follow these steps:

  1. From the home screen, tap and drag the Notifications bar downwards.
  2. Tap the Settings icon.
  3. Scroll to, then tap Storage.
  4. If the memory card has not already been mounted, tap Mount SD card.
  5. Tap Format SD card.
  6. Tap Format SD card.
  7. Tap Erase everything to confirm

Problem #5: Galaxy S5 has flickering green/black screen, won’t turn on

My mom has a Galaxy S5 that suddenly had a flickering green/black screen. It won’t turn on and show the logo, go to hard reset or the reset menu, or go into safe mode. Battery was taken out and put back in after a minute, and the SD card was removed as well. Phone has been babied, not dropped, and kept clean and had a factory reset less than a year ago. It also isn’t connected to any phone service as it’s used as a Wifi device only. As far as she knows there’s been no updates and no new apps installed recently. It’s been behaving perfectly with no glitches. She was playing a game she plays every day and it just flickered this green/black screen, then went blank. LED light will go red or green when plugged in to charger or will go white when trying to get to the reset menu. I’m thinking it is just a display issue but it seems so sudden. If you have any advice I’d be eternally grateful! — Christina

Solution: Hi Christina. If the phone has been used for a few years now, it’s possible that the problem may be battery related. The Lithium-ion battery may have lost its ability to hold a charge so it’s good if you can try to use a new one. There’s no guarantee that a new battery will fix the issue but it’s the only thing that you can do at this point.

If you’ve already tried to power the phone back on to different alternate modes without positive result, there must be a hardware problem behind the trouble. In this case, you want to send the phone to Samsung or to an independent service center.

For reference, here are the steps on how to boot your phone to different 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 #6: Galaxy S5 wifi keeps dropping due to incorrect APN

Hi. Droid guy. I have the Samsung Galaxy S5 and my carrier is through Walmart Family Mobile. Well i pay them but somehow T-Mobile is in on this as well. I have century Link as my internet provider and i have a couple questions.

This phone is a refurbished from a mall kiosk a couple years ago and within a couple months i broke the charging port. So phone sat for a year and now it’s running. The wifi drops constantly. I have:

  • soft reset,
  • turned the smart option off
  • turned phone/wifi router off and on
  • Cleaned the cache through the soft reset.

Nothing seems to help. The APN wasn’t listed even after my carrier sent me a couple texts for data/mms and something else. So i added one from family mobile. Any suggestions?

I Googled this model and read this phone is from Canada. I’m not sure if that means anything but figured I’d throw it in. On the APN, there’s a virtual network operator type (reads GID) and value (reads 4D) tabs. They are not listed in family mobile APN but when i erased them the wifi dropped. I’ve tried everything and have read many of your articles and I’m hoping you can help or offer advice. I don’t have a warranty since it’s a Kiosk $300 special grrrrr lol. Thank you for the time you took for reading my email. — Kim

Solution: Hi Kim. We can’t see the logic of your phone’s wifi dropping when there’s no correct APN settings so there must be a separate unknown software glitch. APN settings are only applied to mobile data function so we can’t explain why your phone’s wifi behaves erratically when the APN is changed.

Try to install the latest Android update first to see if that will make the wifi function work normally. System updates can sometimes include updates for a phone modem firmware. This modem firmware is used by the networking chip to allow you use your phone wirelessly. If it’s outdated or buggy, it can potentially lead to wifi or mobile data function.

If there’s no available update for your phone at this time, do a factory reset and observe how the phone’s wifi work. Make sure that you don’t install any app or updates during the observation period. Refer to the steps above on how to factory reset your phone.

Problem #7: Galaxy S5 stopped working and won’t power back on

Hi. I own a Samsung Galaxy S5. I was using it normally, like I do everyday, and while I was writing to a friend on Facebook, suddenly the screen just blacked out and the phone stopped working. I tried the power button and the phone turned on showing me the logo of Samsung S5 and it showed: Android update 5 of 10, and then blacked out again. After that I haven’t been able to turn it on. I tried several times to take off the battery then put it back and turn it on, or take the battery out, hold the power button for longer than a minute (as you suggested), then put the battery back and turn it on… nothin. It just vibrates when I try to turn it on. I put on a charger because I thought that maybe the battery died, and it’s on the charger for already 30 mins, and still nothing, just vibrates. What am I suposed to do? :/ Please help, thanks. —  Ana

Solution: Hi Ana. Please refer to our suggestion for Christina above. Basically, what you need to do is to try to see if it’s a battery issue by using a different one. You also want to check if you can start the phone to alternate modes (recovery mode, safe mode, and Odin mode). If that won’t work either, send the phone so it can be repaired or replaced.

Galaxy Note 4 fast charging won’t work, won’t charge up to 100%, other issues

Welcome to another #GalaxyNote4 post for this week. We bring you another batch of common Note 4 problems in this one so we hope that you’ll find this material helpful.

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 freezing and shutting down on its own

Recently, my phone has been lagging and the screen would freeze after I downloaded a few apps. Then one day the phone shut off and wouldn’t turn back on. I did a soft reset and it would work but the problem would happen again. Every time the problem occurs, I do another soft reset and it would work again.

One day, I got an error message that says, “cannot boot in normal mode” along with a bunch of other things. I called tech support who told me to take the battery out and put it back in after 10 seconds and it would work again. The phone still shuts off and won’t turn back on and a soft reset always works but every now and then I get that error message again that says “cannot boot in normal mode.” Again, I reached out to Samsung tech support who told me to take out the battery for 10 seconds and put it back in and it would work.

A few days ago, I uninstalled all the apps that I downloaded prior to all these issues and did a software update. The phone had been working fine ever since but the problems are coming back again. It seems to happen every time I try to charge my phone. This has been going on for over a week now and I want a more permanent solution than taking the battery out all the time. This problem happens even when in safe mode. Any ideas what it could be? I really don’t want to have to buy a new phone. — Mimiexue

Solution: Hi Mimiexue. Try to recalibrate the battery and observe how your phone works for a couple days afterwards. This procedure should force the phone to retrain Android on how to detect battery levels correctly. Sometimes, inaccurate battery readings can cause random shut downs. Here are the steps that you want to do:

  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, do the more drastic factory reset. This should be the last software troubleshooting step that you must do. Factory reset returns all software settings to their defaults, which means that the device should be in a stable condition software-wise. If the problem is caused by a software bug, it should be absent after a factory reset. To get a baseline performance, make sure not to install any app right after a factory reset. Let the phone run for another couple days without any apps. Use it normally by doing texts and calls and let it run. If everything is normal and the phone does not shut down on its own at all, that’s a sign that the cause of the problem is software malfunction or a bad app. To see which of them is true, you must install apps one by one so you can observe how the phone works after some time. This will take time but is the only effective way to identify the cause, especially if it’s an app.

On the other hand, if the issue returns after a factory reset and even without any apps installed, you can bet the problem is due to bad hardware. It can be the battery so try to replace it first. Make sure to calibrate the new replacement battery before using it fully. If the problem persists, send the phone for repair or replacement.

For reference, these 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 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 2: Galaxy Note 4 fast charging won’t work, won’t charge up to 100%

I have a Samsung Note 4 that I bought in 2014. My phone charged beautifully within hour or less to 100%. Now, whenever I connect my phone to the fast charger, it says it’s fast charging but it charges slow. In fact, I leave it for 2 to 3 hours and the phone only charges up to 85% to 90%. It never goes past 90%. I did complete the soft reset by removing the battery for 10 seconds and restarting the phone. I also did another soft reset by removing the battery and holding the power button for a minute with no luck. I cleared my cache, and cleared any debris from the charging slot with no luck. My charger is in good shape since the day I bought the phone. I have kept it the same way since day one but I don’t know why it’s not charging fast. I have noticed one thing that when I remove the battery and place it back in and then turn my phone back on, my battery level shows as 100% but before that it would continue to show 85 to 90% not going past it. Today, i charged my phone for 4 hours and my battery level is showing at 88% for over 30min. Please help! — Abhishekmahendru

Solution: Hi Abhishekmahendru. Based in our own experience and from reports from others users with a similar problem, the cause is mainly a bad charging port. To check if that’s true in your case, below are the steps that you can try (minus the steps you already mention):

  1. use a different known working USB cable and fast charger
  2. Try a wireless charger (Note 4 wireless charging requires additional upgrade so it’s up to you if you want to try it)
  3. Recalibrate the battery (steps provided above)
  4. Do a factory reset (steps provided above)
  5. Change the battery
  6. Submit the phone for repair or replacement

Problem 3: Galaxy Note 4 is laggy and randomly shuts down itself

For a couple of months every time my phone shuts off, it would not turn back on unless i took battery out and waited about an hour. It would then be super laggy and shut itself off again. I had to install an app called wake lock to stop the screen from going black and shutting off my phone. The partial wake lock helped my phone stay on. My phone is now trying to update. It will say installing update, get to 100% then just shut off and not do anything else. I then have to take battery out, wait a while and put battery back in to power it back on. It then goes into update screen again. Please help. I don’t know how to get it to finish update so i can have phone working again. — Clarelouise1982

Solution: Hi Clarelouise1982. Android troubleshooting is more of a trial-and-error rather than a sure-fire way of identifying the cause so if you’ve already exhausted software solutions, including of course the temporary workaround of installing Wake Lock app, then you must be dealing with a hardware malfunction here. Please check our suggestions for Abhishekmahendru above. If those steps we provide above won’t work in your phone, consider a repair or replacement.

Problem 4: Galaxy Note 4 won’t connect to network after charging port replacement

I recently replaced the charging port on my Samsung Galaxy Note 4 and have since had Network connectivity problem. I have reopened the phone and made sure the signal cord is probably fitted on the small knot on the charging port , as well as one on the motherboard. I have factory reset but the problem is same. My network provider is sky mobile. When Sky SIM is in , network search displays EE, but in my bedroom you can see Vodafone, EE and Sky. When l connect to Sky , it will say not connected to sky. I called sky to help manual setting before resetting phone but nothing has worked. Please help. No money to go for formal repair. — W Laryea

Solution: Hi W Laryea. We have virtually no knowledge of your particular phone and how your repair goes so we can’t say for sure what happened. Since the phone appears to detect multiple networks at one time, this is definitely not an issue about hardware failure. There must be some configuration issue that must be worked out with your carrier to register the phone in their system again. It’s also possible that the phone’s network programming was changed for some reason after the repair so if working with your carrier won’t work, you’re out of luck. Only Samsung can check if the phone’s modem is programmed correctly or not so if you want to get to the bottom of this, you’ll have to ask their support

Problem 5: Galaxy Note 4 won’t install Android update

Hi. I have a Samsung Galaxy Note 4 that I bought in December of 2014 from Walmart and use through the Straight Talk Service. My phone is basically stuck on Android version 4.4.2. When I check for software updates it says, “the latest updates have already been installed” but obviously they haven’t. I have tried specifically calling the Straight Talk tech support and they had absolutely no idea what I was even talking about. They just kept saying, “you need to be under WiFi to update your phone.” But even under WiFi it still says the latest updates are already there. Most of my apps work well, but my phone not being on the latest update doesn’t allow me to have some features from certain apps. Thanks in advance for any help. — Marissa

Solution: Hi Marissa. If you have a computer, try to install Samsung Smart Switch to it  and see if you can update your Note 4 after linking it by USB cable. If there’s an available update for your device, Smart Switch should tell you so the moment it detects your phone being connected. If it doesn’t, that means that you’ll be unable to  update it via that app.

If you badly want to install a new Android update, you can do so manually via flashing. Keep in mind though that flashing is basically modifying core system files, so if it’s not done properly, you may end up with a bricked phone. Should you want to take the risks involved, go online and find a good guide on how to do it on your particular phone model. Exact steps vary by phone model. This means that a flashing guide for Verizon Note 4 may be a bit different from a guide for Straight Talk Note 4. Be very careful in using the firmware version since using an incorrect one can lead to boot loop problems.

Problem 6: Galaxy Note 4 with new motherboard can’t decrypt SD card

Hi there. I have a Samsung Galaxy Note 4 with an encrypted 64GB SD card. One week ago the device hang and by rebooting it never passed the welcome screen. Samsung told me the motherboard is not working so I replaced it. When inserting the SD card the message appears that the device is preparing the SD card / check for error which is still the current state. Using the SD card with PC, all info is accessible with file extension like jpeg and so on but cannot open because encrypted. I also tried another Samsung phone and same message comes up. After the breakdown the first thing I did was copying the whole SD card to my laptop. Any advise how to get the files from the SD card ? Would be great if yes. Thanks a lot in advance Best regards. — Karl

Solution: Hi Karl. Unfortunately, an encrypted storage medium like an SD card can only be decrypted by the device that coded it previously. Since you had the motherboard replaced, your phone is now basically a “different” phone and can no longer decrypt the card. The same is true even if you use another Note 4 or any other device. The strength of encryption is also its main weakness in this case so you’re out of luck. There’s no way you’ll be able to decrypt the SD card.

Problem 7: Galaxy Note 4 loses battery fast when not connected to a charger

Hi there. My name is Ameerah and I own a Samsung Galaxy Note 4. I’ve had it for just over 3 years now and it hasn’t been giving me problems until now. My phone’s lights of the buttons at the bottom end won’t stop flickering and if I try to use my device (even just unlocking it) it just switches off in a few seconds while I’m using it. Before it did this it would freeze and I would hold the power button for a few seconds and then it would come back on. The battery would end up going from eg. 58% to 23% when it switches back on, and the lights would start flickering again.

I’ve noticed that if I keep my phone in charge, the flickering stops and it works as normal. But I don’t like using it while it’s charging. I was hoping if you could please help me out as to maybe what is causing this issue.

I feel as though it might be the battery and I have read about opening the back and the connection with the battery and so on, but I just wanted to know if it is the battery or something else.

Also this has happened before but not as bad. before I thought it was the RAM being full. I downloaded ‘clean master’ as well as “CM security.” After about a week or so my phone worked perfectly fine. This happened about a year back. But now it’s worse. — Ameerah

Solution: Hi Ameerah. It does look like a battery problem to us. Make sure that you follow our suggestions for others above by recalibrating the battery and doing a factory reset. If those two won’t improve the situation, get a new battery.

Problem 8: Galaxy Note 4 reboots when using some apps

I have a 3-year old Samsung Galaxy Note 4. Sometimes, my phone turns off by itself and it keeps attempting to reboot (it vibrates and displays Samsung text) but does not succeed to reboot until I plug it back for charging. As soon as I plug in for charging it shows 0% battery. Within a second or two it will show the original battery percentage it had before turning off automatically. This happens when I try to use some heavy weight apps like Google maps, Uber and sometimes with Google browser.

There are days when the reboot happens 3-4 times a day and sometimes it does not happen at all specially the days when I don’t use any app, just use it to make calls. My Samsung Galaxy Note 4 was bought from AT&T but I am using it on Cricket Wireless. — FN

Solution: Hi FN. Despite some similarities of your issue with others above, we would like to think that your phone may be having a problem with its power management IC. That’s because the problem appears only at random, and only when you’re using apps that require a lot of computing resources. We still encourage you to do the basic software troubleshooting stuff though such as battery calibration, factory reset, flashing back stock firmware (if you’re running custom ROM), unrooting (if phone is rooted), and battery replacement. If all of these won’t make any difference at all, have the phone replaced.

Problem 9: Galaxy Note 4 stuck in Samsung logo screen, keeps saying battery compartment is open

Hi. I have an Note 4. I have removed the battery, left it out for an hour and tried a complete wipe. As I write this, my phone is flashing the Samsung logo and nothing else. Previous problems include physical problem, the port cover is broken. Have just replaced the Samsung battery with a genuine one (well it says Samsung on it). it comes up with a Touch wiz error and also an error saying to close the battery compartment which I have done, several times. It has been playing up for a while. I am currently in NYC but the phone is a UK phone with a UK SIM card. I will continue to try and do some more hard resets. — Barry

Solution: Hi Barry. There’s only so much an end user like you can do in terms of Android troubleshooting. If you’ve already tried a new battery and factory reset before contacting us, then the problem must be on the hardware side. The only other software trick left for you is to try flashing an older or newer Android version. We doubt that it will change anything but again, as we’ve said, there’s not much that can be done on your end. Software troubleshooting can only fix software problems. There’s no amount of resets that you can do to fix a hardware malfunction.

We can’t tell you what that malfunctioning hardware is unless a thorough hardware diagnostics is done. If you want to get to the bottom of the problem, submit the phone to Samsung so it can be tested. Otherwise, simply consider a phone replacement.

Problem 10: Galaxy Note 4 keeps dropping calls, apps keep freezing, crashing

Respected all. My Note 4 was a perfect machine till last week. All it happened sudden without any pulled activity. During random outgoing calls each day on a Mid-workings hours point 2 – 3 calls were dropped. I blamed on network as usual and moved to some other engagements, some random checks on notifications realized me that my cell is not ringing. I didn’t pay much attention and tried to get back to those missed calls which were missed because of x-y-z reason. All calls were established but without voice at either end. Since that day my all voice functions of Note 4 are retired along with application hanging concern. I consulted with an software expert who has flashed it a couple of times. It works fine with every voice function of the device for next couple of minutes after a fresh ROM. Then again silence. Sorry for the extra briefing. — Meer

Solution: Hi Meer. Since you’re using a non-official ROM, we recommend that you try to find answers from the developer of the software you’re using or from the community that also uses it. The solution to your problems may be ROM specific and we have no idea about it.

The most that we can tell you about this issue is to flash the official Samsung firmware first, and if that won’t work either, to contact your carrier about disconnected calls issue.

If you continue to experience app lock ups even when using stock firmware, you should do a factory reset and observe how pre-installed apps like the built-in Phone app works. If everything works normally when there are no third party apps installed, you can bet one of the apps you install that’s not from Samsung or Google is to blame.

How to change the appearance of Galaxy S7 after updating to Android Nougat, other issues

Hello everyone and welcome to our #GalaxyS7 article for the day. We’ve been receiving more S7 issues in the past weeks so we’re gradually increasing the frequency of our published articles. If you can’t find a solution for your issue here, be sure to keep watching for more S7 articles 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 S7 can’t read encrypted SD card

The phone isn’t reading my encrypted Micro SD card. I was using it normally and then I tried to open a picture in the Gallery and the album wasn’t there. At first I thought I was in a different root but then I realized that the phone wasn’t reading and opening the information in the SD. I turned off the phone, removed the Micro SD and mounted on my laptop. I was so happy to see all my albums and files in the SD. I tried to open any file BUT surprise, my info is encrypted. I return the SD to the phone, turn it on but nothing. If I go to the security menu on my phone / Encrypt SD card, I have the 2 options: decrypt and encrypt. If I try to decrypt the card, the process start searching and then crash. So? What can I do? I can’t format the card, but I can’t format the phone either so what’s wrong? — Juan Pablo

Solution: Hi Juan Pablo. We have no way of telling what exactly is wrong why you have this situation. All we can do is speculate but unfortunately, that won’t fix your issue at all. To be honest, there’s really nothing much that you can do. Perhaps, a software glitch hit something that changed some operating system configuration. Again, we can’t be so sure about that. Doing device troubleshooting like factory reset is a big no-no so that leaves you with SD card reformat option, which obviously deletes all your data. Inserting your SD card in another phone is definitely out of the question.

We are not aware of any effective third party recovery tool out there but if you think your data is worth a few hundred dollars of investment, consider using the services of companies that specializes in data recovery. There’s no guarantee that they can successfully access your files so be ready to part ways with your money if that happens.

Try using Google to look for reputable companies that can help you. Be sure to let them know of the entire situation so they can give you advise before paying up.

Problem 2: Galaxy S7 won’t turn back on after used under water

I took underwater photos with my Galaxy S7 phone (it was under water for about 3 or 4 seconds and it was just 3cm under the water). I don’t know if that matters but it happened in Greece and the water has much salt in it. After I went out of the sea I noticed that the phone doesn’t work correctly and doesn’t accept my commands. I put it next to me in order for the sun to dry it. It didn’t work so I got home and wrapped it in a towel and waited for about an hour and it didn’t start to work. After all, I decided to leave it on the shelf with the SD card out of it because there was nothing left that I could do in that situation. We are on a vacation and I can’t take it to a technician. Can you please tell me if I can do anything else because after everything I have done the display still doesn’t work. I also restarted it from the power and the volume down buttons two times because it can’t shut down. It just doesn’t accept any of the commands I try to give it. I’ll be very thankful if you give me any advise for that problem. — Elizabeth

Solution: Hi Elizabeth. Although a Galaxy S7 is rated as water-resistant, it’s not fully water proof. Dunking it in free flowing water might still damage it and we’ve already seen a lot of such cases before. Not exactly a confidence builder for an expensive device marketed as almost water proof.

Anyway, if your phone is dead and doesn’t respond to any hardware button combination at this time, there’s nothing much that you can do. The best thing that you can do right now is to wait until you get home so you can send it to Samsung. The hardware must be checked so it can be assessed if repair can fix it.

Problem 3: How to customize notification settings in Galaxy S7

I just got the Galaxy S7. Yesterday, when my screen was locked/black, it showed the date, time and battery level as well as any notifications from messaging and emails. Today the messaging and emails don’t show up. How do I get that back?

Also, I don’t like that when a text come and I unlock the screen the text is showing up in a large box in the middle of the screen. Is there a way to change that? — Emily

Solution: Hi Emily. To fix these issues, you must customize how each app shows notifications. Below are the steps on what you need to do:

  1. Open the Settings app.
  2. Tap Notifications.
  3. Look for the app you want to turn notifications for and tap it. This will turn on notifications for this app.
  4. Tap ADVANCED at the upper right hand side.
  5. Select the app you want to set the notifications for.
  6. Select the setting you want. The explanation for each option should be easy to understand.

Problem 4: Galaxy S7 drains battery power faster when using AT&T SIM card

I’ve had my Samsung Galaxy S7 for over a year with T-Mobile as my carrier. Soon I will be moving from California to Iowa. The location in Iowa has no T-Mobile coverage, so prior to moving, I have decided to switch carriers to AT&T. Herein lies my problem. I used to get upwards of 24 hours on a full battery charge. The very moment I switched to AT&T, I noticed a serious and rapid drain on my battery and I can literally watch the % go down. I am lucky to get 3-4 hours now, and have it constantly attached to my portable charger.

I have not changed anything on my phone, no updates, no new apps, no settings adjustments. The ONLY thing I did was replace my T-Mobile SIM card with the new AT&T SIM card and that is all.

Of course, the AT&T reps deny that my battery issues are caused by their towers or switches, and instead, suggest I buy a new phone (or battery at the very least). I checked Battery Usage and I show only a couple of apps using less than 3%. Nothing out of the ordinary. Any help would be greatly appreciated. Thanks. — Ray

Solution: Hi Ray.  We can’t think of any logical explanation for the problem other than the possibility that your phone may be working harder to establish good connection to AT&T network compared to when it was still in its mother network (T-Mobile). Keep in mind that your phone is still running the T-Mobile firmware. This means that everything on it has been validated to work efficiently with T-Mobile system. Now that your still running a T-Mobile software but using the network settings of AT&T, some things must have changed, causing the device to spend more battery or processing power. We can’t be sure of this for sure but since you’re positive that the only change you’ve done is to use an AT&T SIM, this is the most likely explanation. Try to factory reset the device and see how it works. If that won’t solve your issue, you just have to accept the situation.

Below are the steps on how to factory reset your S7:

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

Problem 5: Wet Galaxy S6 won’t power back on

Hello. So, my Galaxy S6 got wet. Not submerged. Just wet. My daughter splashed water on it from her bath (it was sitting on the bathroom floor) and I didn’t notice until about 10 minutes later. I took it out of the case and wiped the water off. It appeared to be fine. Then the touch screen stopped working. The phone is still on (at least until the batter dies) and because the touch screen isn’t working, I cannot turn it off. It doesn’t have a removable back either, so I don’t know how to go about taking it apart further to let it dry out. It is sitting in a bag of rice right now (dumb, I know, but what else can I do?) and before I put it in, the power button on the right side of the phone had also stopped working. What should I do? Can I take it somewhere? It is a Straight Talk phone. — Cailtinjmichael

Solution: Hi Cailtinjmichael. Unlike the Galaxy S7 and S8, your S6 does not have water resistance protection so even a splash can hurt it bad. Putting your phone in a bag of rice won’t do much at this time. Bring the phone to Samsung or an independent service center so the hardware can be checked. A professional also needs to check the hardware so it can be assessed if a repair will likely fix it or not.

Problem 6: Galaxy S7 won’t charge, won’t turn on

I have a Galaxy S7. Yesterday it froze and it won’t reboot at all. When I plug it into the wall, it shows a battery with a lightning bolt but it doesn’t fill up green showing it’s got charge. I have tried all the possible reboot fixes by holding in the power key and volume keys ETC but none of which have fixed the phones issue. I’ve looked all over the net but nothing seems to give me the right advice. — Kailadobson58

Solution: Hi Kailadobson58. The tips and possible solutions that you’ll find online are mostly intended to fix software causes of this problem. If your phone no longer boots up right now, that means that you can’t perform any of the suggested software tricks that you’ll find. It also means that bad hardware is the mostly cause of your problem.

Try to charge the phone with a different charger and USB cable and see if that will work. If you have a wireless charger, you can also try that to see if the problem lies in your phone’s charging port.

If you can’t power the phone back on using any of these means, have it repaired or replaced.

Problem 7: Accidentally dropped Galaxy S7 has cracked screen

I dropped my phone and there is a small superficial crack on the bottom by the home button. If I hit the power button, my screen goes black; it stays on. I can hear the pages opening or the volume buttons. Everything is responsive except the screen. it will blink and if I mess with it for a couple hours I can get it to light up. But I can’t let the display go dark or time out. Cuzco I’m screwed. — Jennifer

Solution: Hi Jennifer. If you want to fix the problem, you should stop looking for any software solution. There’s no amount of software tweak that can be done to fix a damaged hardware. Contact Samsung and have the device repaired or replaced. If your phone was part of your subscription plan, contact your carrier so it can be replaced.

Problem 8: Galaxy S7 apps keep crashing after installing Android Nougat

Hi. I recently updated my phone to Android version 7.0 and it is a nightmare. The most important issue is that I can’t view my messages or text on the system’s messaging app. When I tap to open… it immediately shows this message on my screen: “com.android.cts.ctsshim has stopped” or “com.android.cts.ctsshim keeps stopping”. Please help me what can I do to fix this problem? Many thanks, Sabrina P.s. if possible I’d like to avoid doing a factory reset. Thanks. — Sabrina

Solution: Hi Sabrina. The first possible solution to your problem is cache partition wipe. Do that and observe how your phone works for some time.

If the problem returns, make sure that all your apps are up-to-date and compatible with the current operating system. Even if the specific app you’re having problem with is okay, it’s possible that one of your apps is affecting the working ones. Go over your list of apps under Google Play Store app and make sure to check each one if it’s compatible with Nougat (Android 7.0). You can also observe how your phone works when it’s on safe mode. This will help you tell if one of the third party apps is to blame or not.

Below are the steps on how to restart your S7 to safe mode:

  1. Turn your Galaxy S7 off.
  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.

If nothing changes even when your phone is safe mode, do a factory reset.

Problem 9: Galaxy S7 screen flashes green, screen won’t turn on right away after a restart

So, I have an S7. I began to notice something. Every now and then, when I turn off my screen, it would flash green, then turn off and when I try to turn it on again, it doesn’t turn on after I try for a few minutes.

Also, whenever I leave it in a cold environment, the same thing tends to happen. I tried asking somebody about it and they said it might be because I dropped it. I’m not sure if that is the case so that’s why I’m asking here before I pay for a repair. Hope you can reply, and thanks. — Cedric

Solution: Hi Cedric. Most issues about erratic or discoloration of the screen are caused by hardware malfunction. If you did dropped the phone badly before, that may have damaged something in the motherboard though it’s only now that you’re seeing the negative effect. Like water damage, the unnecessary shock from an accidental drop can lead to anything. For some, issues can begin showing right away, while in some cases, much later.

To check if hardware issue is to blame, do a factory reset first and observe the phone for a day. During this time, try to replicate the issue by doing the things that you normally do when this issue occurs. If the issue won’t occur, a software glitch may be to blame. That’s good news since you can most likely fix it by removing a problematic app, installing an update, or flashing.

If the problem continues even after a factory reset (and without apps installed), you must have a hardware issue at hand. In this case, you should consider repair or phone replacement.

Problem 10: How to change the appearance of Galaxy S7 after updating to Android Nougat

Hi guys. It’s not so much a glitch but everything seems dull and boring in the update. When I get emails, there is no colour to differentiate new emails from old ones and all the writing is the same size, nothing stands out. In the notification window the writing is like outlined as opposed to the writing being filled in like, it’s kinda ghost writing. It’s horrible. Can I change the text on everything? — Davedave1973

Solution: Hi Davedave1973. If you don’t like how the new update changed the previous look, there are a number of options that you can try.

Firstly, you can try to download a new font to replace the existing set of fonts. You can change the font, font style, and font size by going under Settings>Display>Screen zoom and font.

If changing the font won’t be enough, you can also try to change the look of some aspects of the phone by using a different theme. Just go under Settings>Wallpapers and themes.

Finally, you can also change the overall look of the phone by using third party launchers. Try to take a look at this link and visit a website that lists some of the popular Android launchers nowadays.

Problem #1: Galaxy Note 4 won’t read encrypted SD card

Hi. i have Samsung Note 4 which i am using for more than 18 months. A couple of months back i have inserted 128GB SD card and it was working fine. At certain point i encrypted the SD card and it was working fine until yesterday. I have captured a video for say 3 minutes and after that it was showing on top SD Card Encrypting and i thought that since the video is big it is taking a long time. wake up this morning and still it shows the same and i could not see any of my files in gallery. Went through my folders option and SD card is not showing there but it shows SD card is ready. restarted the phone and tried a lot but it is showing the same, few hours back i tried to decrypt the SD card but it says “Error Decryption SD Card.” i inserted the SD card through a computer and i can see all the files but could not access. Please help me to recover my files. — Fhirnaz

Solution: Hi Fhirnaz. The only device that can help you recover your files is your Galaxy Note 4. An encrypted SD card can only be read by the device that encrypted it in the first place. If your Note 4 no longer is no longer able to read the SD card properly or can’t even decrypt it, that’s unfortunate. That means that those files are good as gone. The only suggestion that we can think of is to refresh the system cache. If that won’t work either, an unknown glitch may have caused the phone to suddenly lose the ability to decrypt or read the SD card.

For reference, below are the steps on how to wipe the cache partition:

  • 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.

Problem #2: Galaxy Note 4 can’t install Android update

Hey. I’m having an issue with the Note 4 updating. I’m currently running Android 5.1.1 from T-Mobile. Every time I try and do the update it looks like the update downloads fine and prompts me that my phone will do a restart. This is where the issue happens. As soon it restarts in the top left corner it says something about system rebooting written in blue and my phone continues the start up process like it normally would and goes to the my lock screen. After I unlock my phone a pop up comes up and says the update couldn’t be done and then I get the option to send the report which vary in size from time to time. I have tried using smart switch which doesn’t work. And I also did a factory reset on my phone and unfortunately doesn’t work as well. Any help would be appreciated. Thank you. — Ron

Solution: Hi Ron. There are a number of requirements in order for a device to download and install Android update. Make sure that all items are covered in your case.

  • Phone must have a minimum of 3GB internal (not SD card) space. In some cases, at least 6GB may be needed depending on how big the APK file is and how much more is needed once the system starts to open the compressed files.
  • Battery must have at least 70% left to ensure that the power won’t cut off while the system is doing some critical changes.
  • Good internet connection during the download to ensure that the phone receives the complete set of files. If you’re using mobile data to download the update, switch to a more reliable wi-fi network.

Once you have all these three things taken care of, do another round of factory reset before attempting to install the update again. Make sure you don’t install any app.

If the installation fails again, visit your local T-Mobile store and let them manually update the phone for you.

Problem #3: Cannot use Galaxy Note 4 due to Factory Reset Protection (FRP)

Here is my problem. I’ve been trying to bypass the FRP on a Galaxy Note 4. I got it from my sister-in-law a couple months ago. She doesn’t remember the email or pass code for it because it was just her old work phone and she set it up hastily because she uses a iPhone and that is what she is used to. She has tried taking it to Best Buy reps but they can’t do it because she doesn’t remember the email and all they will tell her is the first letter to it. So since i inherited this phone I’ve been trying to unlock it to use for my myself. I’ve tried the OTG and stuff but nothing seems to get me by. Samsung won’t do it cause she no longer has a proof of purchase. I don’t want this phone to go to waste. it has wizard setup and its a pain. help me please. — Cody

Solution: Hi Cody. If the original owner can’t provide the Google account credentials for this phone, it’s good as useless. Samsung can’t help you in this case either, even if you can present a proof of purchase. The only hack we know then was to insert an OTG cable to hopefully trick the phone into thinking that a user is trying to update it manually, or trying to access the memory. As mentioned in our previous posts where this trick was suggested, Samsung may eventually get wind of it and patch it up. If this trick no longer works in your Note 4, then Samsung may have already updated the software to prevent this hack from working. We are not aware of any other similar hacks so right now, that Note 4 of yours is just an expensive paperweight. We’ll update this post once we’ll come across another effective way to bypass FRP.

Problem #4: Hover Zoom feature won’t work after restarting Galaxy Note 4

Hello. Recently I started using Hover Zoom on my Samsung Note 4. With this feature enabled, the area directly underneath my S Pen is magnified which is exactly what I need. My problem is that when I power off and on my handphone, Hover Zoom stops working even though the feature is enabled in accessibility menu. I have to disable and enable the feature in accessibility menu before Hover Zoom works again. Each time my handphone is powered on I have to do this. Is this a bug or something else please? My Note 4 runs on Android Marshmallow OS and Nova Launcher. Thanks in advance. — Roger

Solution: Hi Roger. Did you do something different before you noticed this problem? Did you install an Android update or install some app updates or apps lately? If you did, try to refresh the cache partition first to see if it works. Steps are provided above.

Afterwards, you can also try to check if a third party application is causing the problem by booting the phone in safe mode. Because safe mode disables third party services, processes, and apps, it’s a must do in this situation. To do that, 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.
  • Remember, if the issue won’t occur while safe mode is enabled, that’s proof that one of the apps is causing the trouble. You need to uninstall apps individually in order to identify the culprit. Make sure that you observe how Hover Zoom works after every uninstall.

Finally, if nothing seems to change after wiping the cache partition and booting in safe mode, don’t hesitate to try factory reset. There may be an operating system glitch that developed for some unknown reasons. To factory reset your Note 4, follow these steps:

  • Create a backup of your important files and contacts.
  • 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 #5: Galaxy Note 4 videos runs at superfast speed when previewed

I read your article about the problems and solutions, and i didn’t find solution about the problem am having. I make lip-sync videos on musical.ly app and i also make videos on Snapchat and B612 app. So the problem is when i finish making videos and when the video previews, it’s superfast on all of the apps i mentioned above. They’re not recorded in superfast speed. It just previews them really fast

So i have to save them to see the result which costs like double time and it’s so annoying. Can you please help me solve it? I’ll be very grateful if you replied 🙂 — Hamxa

Solution: Hi Hamxa. We tried to install all the apps you’re having trouble with in our own Note 4 and the previews of videos taken all play in normal speed. This means that there’s no inherent issue in these apps, which also means that the problem may be unique to your device. There may be another app that you’ve installed that forces the previews of videos to run at a faster rate. To check, do a factory reset and observe how, say, B612 preview works. Make sure that you only install B612 app during this time. If the issue won’t occur, that’s a confirmation that our guess is correct.

If the problem remains in your phone though, we suggest that you contact the developers of the apps involved so they can check into it.

Problem #6: Galaxy Note 4 keeps showing errors about apps not working

Hello! I’m having problems with this phone. When on, it shows the crash messages for various apps, regardless of whether I use them or not, e.g. “Unfortunately, ____ has stopped working.” It ranges from downloaded apps (Spotify, Youtube, etc.) to pre-installed default apps. Sometimes after these messages, the phone shuts down. Sometimes with the Samsung shutdown animation, sometimes without it. After it has shutdown/crashed, it doesn’t restart, and I cannot power it on using the power-button, and the power/vol-up/home button method won’t work either. Only after a long time >20 mins, can it start up.

In response I did a factory reset, as i thought it was one of the apps, but even during the setting-up stage the app crash message showed and the phone crashed again. Help! — Luke

Solution: Hi Luke. There must be a hardware malfunction that causes the software to behave erratically. That the pop-ups keep showing even after a factory reset and during the initial setup is a strong indication that software may not to blame. Contact Samsung or any relevant party for options on how to replace the phone.

Problem #7: Galaxy Note 4 shuts down on its own after flashing stock firmware

Hello. I have Samsung Note 4 Edge. My phone was working fine and then i rooted my device but again i went back to official Samsung firmware. Then slowly my device started having a problem. The battery drains very fast and at first my phone used to shut down at 30% charge, then 40%, and now 50%. It won’t turn on until i put the charging cable. My phone does not turn off until i use anything like apps. My phone works fine but when im near to 50% charge and i use any app my phone shut down and won’t turn on until i plug in the charger. Please help i live in United Arab Emirates. — Fawad

Solution: Hi Fawad. The first solution that you want to try is to calibrate the battery so the operating system can read the levels properly. Here’s how it’s done:

  • 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 battery calibration won’t help, do a factory reset (steps provided above) in order to address potential software-level glitch that may have developed. If that won’t work either, consider getting replacing the battery.
