Problem #1: Galaxy Note 4 randomly restarts | Apps on Galaxy Note 4 keeps crashing

My phone randomly restarts a lot and often crashes when I try to open apps. I did a factory reset on the phone and I still seem to be having troubles with it running very slowly and it doesn’t restart as often as it did before the factory reset. however it still does restart occasionally.

I’m also having a lot of trouble with updating the apps to current versions from the factory version of my phone. It took me an hour to update to the current Facebook Messenger and I’m on quite reliable Wi-Fi connection, and it wouldn’t update through my data network.

When I plugged it in the first few times after the factory reset, the screen would stop working and glitch quite a bit, but also doesn’t seem to be doing that now. I’ve had the screen come up completely blank besides the wallpaper a couple times and it won’t load certain apps either (however apps not loading could be that they aren’t the updated version currently).

The battery life seems to be dropping 5-10% every time it restarts.

Phone is updated to the latest Lollipop version 5.1.1 but there is no update for Marshmallow yet on my phone.

I’m with Telus for a provider.

Any apps I’ve downloaded are popular apps (Facebook, Instagram, Twitter, Colour Switch, Make 7!, etc.) and I couldn’t imagine that those would be a cause of the problems.

I also haven’t downloaded any music within the past week or so or otherwise.

Any idea what would be wrong? — Kass

Solution: Hi Kass. The rule of thumb when troubleshooting an Android device is to go with basic software troubleshooting first. If issues remain after you’ve exhausted all software solutions, you can assume that there’s a hardware issue behind them. We noticed that you’ve already performed a factory reset, which we say is the last software troubleshooting step that you can do. That nothing changes after doing a factory reset doesn’t mean that a hardware issue is to blame. We suggest that you do another round of factory reset and observe the device as long as you can without installing any app. This will help you tell if the restart problem is due to an app or not.

A reliable internet does not necessarily mean a faster internet connection speed. Try to update your apps using a known fast internet Wi-Fi network to see if the slow update issue is due to a phone problem or to a slow internet connection.

If doing these things won’t change issues a bit, consider getting another battery. Doing so may fix the restart and battery drain issues.

Finally, if a new battery doesn’t seem to be the solution, consider getting a replacement phone.

Problem #2: Galaxy Note 4 keeps restarting, freezing, and lagging

This is my sister’s old phone that she was having issues with restarting, lagging, and freezing. I had done a factory reset on the device and without installing any other additional apps to the phone the problem still persist. i switched the SD card from an 8GB to a 32GB Sandisk ultra micro SDHC. Nothing changed… sometimes the operating system won’t work and i get a notification saying to wait or close it.

I’m not able to setup the finger print reader, and cannot when i try to update the operating system it says “software update is temporarily unavailable. try again later.” I know when you polish a turd it’s still a turd but just have hopes to resurrect this turd!

Hope to hear back from you soon with some helpful info! — Patrick

Solution: Hi Patrick. We need a full history of a device in order to be effective so we doubt if there’s any other thing that we can tell that will work. As mentioned to Kass above, if software solutions won’t work, that’s a clear indication that you have a hardware issue at hand. If nothing appears to change even after the phone is fresh after a factory reset, you are out of luck.

Also, if your phone happens to run a custom ROM or if it’s rooted, we recommend that you try to revert all software back to stock. This might very well be your ticket to resolution.

Problem #3: Galaxy Note 4 randomly restart and does not work when it’s not charging

The phone keeps shutting off and tries to restart but can’t. It just goes to the Samsung Galaxy screen then shuts off and repeats itself. Sometimes on rare occasions it turns on and last for a few minutes. It only works when I’m charging it, but sometimes even when it’s charging, it shuts off. I looked at the phone status and battery health says good. I bought a new battery and this one works just fine, even though it’s not from Samsung. That battery also says battery health is good. So I am confused when both of them say it is good but the original Samsung one is not working? Maybe it is something wrong with the phone? Also the new battery I bought is at a much higher temperature than the original. It’s about 37°c and the original was about 32° c. I want to know why this issue keeps happening! — Alex

Solution: Hi Alex. Either your phone is overheating, which results to random restart, or there’s a hardware issue that we don’t know of. That the system appears to show both batteries are in good health can be an indicator of a problem.

To troubleshoot, you can start by booting your phone in safe mode. Booting Galaxy Note 4 in safe mode will temporarily disable all third-party or download apps leaving pre-installed ones and core services running. This procedure can help you determine which of your apps is causing a problem.

  • 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.

Once the device is in safe mode, observe the phone for several hours to know if the phone continues to randomly restart, or still not charging correctly.

If the issues remain, do a factory reset. Here’s how:

  • 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.

Again, you need to observe the phone for hours. If the issues persist, you’ll know that you have a phone problem.

Problem #4: Galaxy Note 4 won’t restart and keeps on freezing

For about 1.5 months I’ve been having various issues with my phone. It seems to freeze up when there is inactivity or freeze when it feels like it, randomly. I have to do a soft reset to get the phone to turn on. Usually there is an Android icon that appears on the phone and it says “it’s downloading” and not to restart the phone, which I have to do, because it just stays stuck on the android icon. it also says “error booting”.

I have tried to do a factory reset, which can never be completed, because the phone won’t restart itself. Also, I can’t do the latest software update because it won’t restart the phone after it uploads the update information.

I’ve dumped most every application that I can, and deleted pictures, texts, videos, anything to clear up the memory space.  Also, I have repeatedly cleared the phone’s cache. I don’t know what else I can try. 

The phone is too expensive to replace, and I don’t have “insurance.”  The phone is also over a year old. I can usually get the phone to work again after a soft reset (removing the battery, depressing the power button, waiting a moment, then replacing the battery). I may have to do a soft reset at least 3 times a day because the phone just locks up. Any different suggestions?

Also, is there a different way to do a factory/hard reset, that doesn’t require the phone to restart itself? (Also, phone cannot be set to restart itself, will only power off.  I also tried the volume up/down and depressing the power button at the same time, which didn’t work at all. Please help. — Angie

Solution: Hi Angie. If your device refuses to restart normally, then there’s no way that you can update your phone or a factory reset. The system needs a complete powercycle in order to make the changes stick.

The only thing that you can try right now is to manually install a stock ROM, especially if your device is rooted or running a non-stock firmware. Otherwise, you simply have to suck it up and make do with what you have.

Problem #5: Galaxy Note 4 won’t boot up normally and randomly turning on and off

Well it all started with my note 4 randomly turning on and off and booting into Odin mode without me initializing it (not able to boot normally error etc). so I did a factory reset and thought that would fix it, but it was all to no avail… Searching online i came across how to actually use odin mode and how it would be fix by downloading the official firmware and re-installing it with odin. I did just that and it fixed it! For a couple of days that is.

It started doing the same thing, so well i did the same thing, but this time while doing it in odin i got “error” and in the phone i would get a “a firmware error update occurred, please go to recovery in Samsung Kies” and i’ve been wanting to try that but now my phone won’t even turn on.

I did all the helpful steps you provided (taking the battery in and out, waiting a couple of minutes/seconds, etc) but it just won’t turn on. I started to think that it might be completely dead, BUT it is somewhat recognized by my PC when i connected it. I truly don’t understand this and i really hope you could help me :/ Thank You. — Nick

Solution: Hi Nick. Well, we need to make the phone to turn back on first. If that’s not possible, then there’s really no moving forward with your case. Needless to say, our first priority is by making the phone power back on. Since we can’t perform any software troubleshooting obviously, we need to look into the hardware aspect. Have the hardware checked. You probably want to make sure first that the hardware buttons are working fine. Have the phone checked by Samsung or any qualified shop so a full hardware diagnostics can be performed.
