Problem #1: Galaxy Note 4 won’t charge properly all the time

Hi. Since the latest update, my phone does not reliably charge. For example, last night it did not charge at all, but when i woke up in the morning around 9 am it started charging again. This inconsistent charging issue is unacceptable because i use my phone for school and work. Luckily i have 4 batteries, 2 of which are extended batteries, and two i can charge in charging cases to switch out once phone battery is drained. Otherwise I’d be carrying around a useless piece of hardware that just adds weight to my pocket. Please fix this issue asap. — Mark

Solution: Hi Mark. An issue like this is usually due to a malfunctioning charging port. This means that if you want to get to the bottom of the problem, you may have to consider sending it in to Samsung so a full hardware check can be conducted.

There are very few erratic charging issues caused by bad firmware but we recommend that you do a factory reset and proceed from there. If the phone continues to charge erratically after a factory reset, that’s a confirmation of our theory. You must then send the phone to Samsung or to an independent service center so it can be repaired or replaced.

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

  1. Create a backup of your important files such as photos, videos, etc.
  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 Volume 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 Volume 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.

Problem #2: Galaxy Note 4 has multiple network-related issues

We have 2 Note 4 phones on the Verizon network. I have spent the last almost 3 months trying to get them to resolve the following issues, but the best they can do is tell me it is a known issue, but there is no resolution yet.

We changed our plan from a grandfathered unlimited data plan to the unlimited everything plan, which was supposed to save me about $50 per month on our bill. Since the switch, we have lost nearly all service on these phones, dropping calls everywhere, no connectivity, even in areas with many towers around, and locations that I have always had very reliable service. We have tried everything I could imagine, and several things I could not, including replacing my phone, replacing the SIM cards, turned on enhanced calling, had modified updates sent to the phone, and a few factory resets. Verizon has stated that it is a known issue, but they have no fix currently. They have suggested upgrading to a new phone to solve the issue, but I cannot imagine having to spend around $800 when my phones will do more than I will ever need, at least they would before this glitch. Both phones began having these issues at the same time, and I have spoken to other people with Note 4 phones, who also have the same issues. Any thoughts are appreciated. — Keith

Solution: Hi Keith. Your issues are all network-related so there’s nothing much that we can do to help, especially if they are happening on multiple devices at once. If your carrier did acknowledge the problem, then you should continue to work with them for a solution. Third party support teams like us can’t help you in this regard. Our services are provided to Android users experiencing device-specific problems. SMS, MMS, voice calling, and mobile data issues should be handled by the network you’re paying to provide you with a good working service. If they can’t fix your issues, we suggest that you switch carriers.

Problem #3: Galaxy Note 4 has black screen issue and won’t charge

Samsung Note 4. Android updated to the most recent version that Samsung sent out – but not sure what version that is. Found to have a black screen. On removing and replacing battery – phone vibrates and initial boot screen appears briefly then disappears. Removing, waiting a minute and replacing the battery has the same effect. Using a different battery charged with an external charger has no effect. No red LED or battery charging symbol when connected to the original Samsung charger (which works with other devices). Doing the volume down and home button brings up the custom OS warning but that vanishes – and the phone becomes unresponsive. Pressing volume up at this point brings up the Android symbol “downloading” Do not turn off target, top left reads (Odin mode, product name gt-i9505, Current binary Samsung official system status official Knox kernel lock 8×8 Knox warranty void 8×8 csb-config-lsb 8-30, Write pProtection:Enable eMMC Burst Mode enabled (writing is very small so the 8s may be 0s with a cross line). Still says downloading – but no progress bar. A bit scared to touch it or do anything so leaving it running and will plug it in! — Tom

Solution: Hi Tom. If your phone’s screen stays black and no longer turns on, there are two possible reasons for it. One is that screen assembly was damaged for some reason and does not work anymore at this time. The other reason is the possibility that there’s an unknown logic board problem preventing an otherwise working screen assembly from working normally. Any of these two scenarios require a thorough hardware check up so there’s not much that you can do in terms of troubleshooting. The only suggestion we can give you right now is to see how the phone behaves when you restart it to alternate modes. Booting to other modes such as Safe mode, recovery mode, and Odin mode does not require touchscreen commands so the main cause of the trouble right now is software-related, the screen should turn back on. It if remains black and unresponsive, that’s a clear sign of a malfunctioning screen assembly.

For the charging issue, the main cause may also be had hardware like a broken charging port so make sure to wipe the phone clean with factory reset. If there’s no improvement even after a factory reset, you can assume there’s bad hardware anywhere. You should send the phone in for repair or replacement.

For reference, here are the steps on how to boot your phone 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 #4: Galaxy Note 4 no sound when using phone speaker

Hello. I have seen this question published in your forums, but here is a different take. Note 4. It is NOT being used as a phone, just for an internet connection to a few sites, usually the same sites over and over. Occasionally, I use YouTube, and recently there is NO SOUND, except through the headphones. The sliders for all three volumes are at the max. The reason for the emphasis that it is not being used as a phone, is because there are no apps or any other types of additions to the original software to complicate the situation. In some of your other helpful replies to this problem, the solutions boil down to (a) do a master reset or (b) have the device repaired.  I’ll do this if necessary, but the device only goes from my desk drawer to the top of the desk — not a lot of heavy or abusive use at all. Could the speaker somehow still go out? Thanks for any help. — Mlourob

Solution: Hi Mlourob. There are tens of thousands of possible points of failure in an ordinary smartphone so even if you’re only using it for light tasks, there’s still a fairly high number of things that can go wrong with it. There’s no way to check every possible angle as to what may be causing the speaker to act erratically so our troubleshooting steps are limited as well. In general, Android troubleshooting is simple — if all software troubleshooting have been exhausted, then bad hardware must be to blame. There are no advanced hacks that we can do to fix the problem. Rather, you want to narrow down the possible causes by doing some simple software procedures and see if it leads you somewhere. There’s no special tools that we can suggest for you to use to see where the problem lies. That’s why we almost always recommend master reset and hardware repair all the time.

If you haven’t yet, make sure that you do the reset first and proceed from there. Master reset will address any software-related glitch that may have developed over time. It restores all software settings to their defaults so it’s an effective way to eliminate any bug brought about by time and usage. Make sure to observe how the speaker works right after doing a reset and without any app or update installed so you’ll see any difference. Android troubleshooting is mostly common sense troubleshooting so if software is cleared, that only leaves you with a bad hardware as the cause.

Problem #5: Galaxy Note 4 cannot create new SMS

When using stock messages app I can not select favorites, groups, or individual contacts freezes on that screen. I can send and receive texts but cannot create new text, only reply to existing text. when starting a new text the issue of not being able to select anything is happening. Just got a message contacts not responding also looks as though they are tied together. Thanks. — Bnrmit

Solution: Hi Bnrmit. The first thing that you want to do here is to delete the cache and data of the apps involved. Doing so will force the phone to use the default settings of said apps by deleting user customizations and updates. 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 the problem remains after dealing with apps involved, wipe the cache partition and see how the phone works afterwards.

  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.

Cache partition wipe is a handy software troubleshooting especially if problems are update related. Be sure not to skip it in this troubleshooting.

You also want to see if the problem is caused by the messaging app itself, especially if you recently updated it. The new app version may be poorly coded resulting to this erratic behavior. If deleting an app’s cache and data as well as the cache partition won’t help, try to use another messaging app and compare their performance.

Finally, if nothing works, simply wipe the phone via factory reset.

Problem #6: Galaxy Note 4 is compromised with malware

My phone has been, if I’m using the correct terms, rooted by a computer and every single app that is in my phone is fake, has fake credentials and has come from a third party. Someone is using an encoding system (utf8) so they are receiving every password and keystroke that I do. I couldn’t even root my phone myself to get rid of their information. My provider, Verizon, tells me that they can see someone’s clearly stopping them but can’t stop the hacker. I can’t receive any voicemails either. I need desperate help asap. I have a one and two yr old and am a stay at home mom with epilepsy. — Angelaf53129

Solution: Hi Angelaf53129. if you think your phone has been compromised, the best thing that you can do is factory reset it first, then eventually reflash the firmware. You need to perform a factory reset via recovery mode instead of going via Settings. If you can’t do the master reset for some reason, do some research on how to flash a stock firmware on your phone to completely remove any malicious apps and services. If you don’t think you can do the flashing yourself, bring the phone to a Verizon shop so they can help you do it.

For your voicemail issue, you must work with network to fix it. There’s nothing that we can do about it.

Problem #7: Galaxy Note 4 not charging with multiple chargers

I have trouble with my charger. 3 months I been buying and throwing away charger cords because they will last awhile then stop working. Recently about 4 weeks ago, I bought 3 chargers off of Amazon Prime with good reviews and ratings. Now none of the chargers work on my Note 4 and they either lasted a day or 2 days. They work on my brother’s Note 2, as if the cord isn’t the problem. I tried many steps including the steps you gave out, but sadly the phone isn’t charging with any charger. — Ty

Solution: Hi Ty. It’s unheard of that a Note 4 damages a charger. In fact, we cannot see any logical explanation for it if it does happen. The most likely scenario is that your Note 4 has a malfunctioning charging port that’s why multiple chargers won’t work with it. Do a factory reset first to see if it’s a software issue. Should the issue remain, have the phone repaired or replaced.

Problem #8: Galaxy Note 4 reboots on its own when using Instagram

Phone used a lot everyday. Almost 2 years old and has recently became very laggy occasionally. It has been powering off and back on by itself. The lagging seems to occur when I am on Instagram and or touch the screen a lot (touch wiz prob?). The powering down seems to occur randomly when I’m not using it and I notice because of the sounds associated with the reboot? Phone is rather full perhaps prob is memory related? Please help?! — Jacob

Solution: Hi Jacob. An issue like this can be caused by one of the following:

  • software glitch
  • bad battery
  • unknown motherboard error

Try to do the basic software troubleshooting first such as wiping the cache partition, observing in safe mode, installation of app updates, and factory reset.

If none of them will work, try to recalibrate the battery with these steps:

  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.

Should the phone continue to reboot randomly, the next step is to use a known working Note 4 battery. If you have a friend with a similar phone, try to use the phone from his or her Note 4 so you can observe if there a difference. If the problem won’t go away, there must be a deeper motherboard problem causing it. You should either send it in for repair or replacement.

Problem #9: Galaxy Note 4 laggy and shuts down randomly

Hi. For the past two days my phone has slowed down and it crashes when opening apps. I did a cache wipe but it still seems to be slow. Even texting takes ages and my phone restarts automatically when opening apps. This is really frustrating. I updated my Viber and WhatsApp two days ago since then I have had this issue. I would really appreciate if you can advise me on how to get this matter sorted had the phone for nearly 2 years now. — Pradeep

Solution: Hi Pradeep. Refer to our suggestions for Jacob above.

Problem #10: Galaxy Note 4 won’t stay on unless connected to charger

My phone started to just randomly shut off and wouldn’t go past the carrier screen until i plugged it to a charger. It doesn’t matter what the battery level is. It could be at 70% or 40%. So i started my phone in safe mode to see if it was an app, phone still shut off. I did a master reset and left all my apps off, phone shut off. My battery has no liquid damage. So now i’m thinking replace the battery? Or is it some other issue? — Renee

Solution: Hi Renee. If you’re positive you’ve already done all software troubleshooting pertinent to this issue, then getting a good battery replacement is the next logical step. If that won’t work either, have the phone repaired or replaced.
