So, read on to know how to fix them.

Note 5 turns off by itself randomly

Problem: Hello droid guy. Got a little problem with my Galaxy Note 5. At random times in a day, the phone just shut itself off and I don’t understand why. This issue has already been happening before and maybe it’s because of my negligence that it has reached this far. I just want to know if it can be fixed and how. Thanks for all your help.

Troubleshooting: There are a few possibilities I can come up with based on your description of the problem; rogue app, firmware issue, and hardware problem. The first thing you should do is rule out the possibility that one of your apps is causing this problem. Boot your phone in safe mode:

  1. Turn off your Galaxy Note 5.
  2. Press and hold the Power key.
  3. When ‘Samsung Galaxy Note 5’ appears, immediately release the Power key and then press and hold the Volume Down button.
  4. Continue holding the Volume Down button until the phone finishes the restart.
  5. When you see Safe Mode on the lower left corner of the screen, release the button.

While the device is in this mode, observe closely to know if the problem still occurs but if it got fixed, then you just have to find the app that’s causing it uninstall it. Unfortunately, we don’t know what apps you have in your phone so we can’t pinpoint the culprit. It’s up to you to find it.

However, if the problem remained, then you have to move on to a different troubleshooting procedure to rule out the possibility that it’s a firmware issue. That said, there’s no other way to do that except master reset:

  1. Turn off your Samsung Galaxy Note 5.
  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 Vol 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.

Note 5 isn’t charging with its original charger

Problem: My phone and it’s battery are less than a year old.  My phone will not take a charge.  I saw a man at Sprint who was able to charge it on his charger, and therefore feels it is a problem with my charger, not the phone.  What can you do to help me?  Thanks!

Troubleshooting: Well, buy a new charger. You positively said the guy at the Sprint store made your phone take a charge with his charger, so apparently, the phone is fine. You know, troubleshooting a phone that doesn’t charge is a bit of a hassle; you have to inspect the charger itself, the USB cable and the USB port on your phone. The thing is you can rule out the first two procedures by buying a new charger. But if the phone still won’t charge with the new power adapter, then it’s time you sent it in for repair.

Note 5 charges very slowly

Problem: My Note 5 charges but very, very slow. Even if I had to leave it plugged in overnight, in the morning, it would be at around 65% or less. One day, I tried leaving it plugged in for almost 24 hours as I left it at home when I went to work. In the evening, it was at 91%. It was really disappointing considering I’ve taken care of it since I bought it in September. If there’s something you can do, please help me fix this problem. Thanks a lot.

Troubleshooting: At least, the phone charges and that’s a good thing because it’s a sign that the issue isn’t with your phone’s hardware. The best thing to do is boot the device in safe mode and plug it in. When there’s a bunch of apps and services running in the background, the battery drains quicker. So, if you plug it in with all those thing running, the charger may not be able to push enough power to charge the battery. Booting it in safe mode will temporarily disable all third-party apps and services and if it charges normally in that mode, it’s time you cleaned up your phone of unused apps, minimize the use of widgets, turn off syncs, disable some features, at least, while you’re charging.

However, if the phone still couldn’t charge normally in safe mode, the only thing left for you to do is master reset to bring it back to its default settings. Of course, you have to backup all your data because they’ll be deleted during the process.

Note 5 keeps restarting on its own at random times

Problem: I think it was after a minor software upgrade that my Note 5 started rebooting on its own, although not that frequent. Yesterday I think it rebooted 3 to 4 times and while these numbers may seem “few,” I am still very disappointed because a smartphone shouldn’t do that let alone an expensive high-end device. Help me fix it please.

Troubleshooting: The key to solving this problem is knowing what triggers the reboots. There must be a trigger considering it happens randomly and not that frequent. I suggest you boot the phone in safe mode and continue using it as before while all third-party apps temporarily disabled. If the problem still occurs, then try wiping the cache partition. For issues that occurred shortly after an update, this procedure is very effective:

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

If it failed, then it’s time you reset your phone.

Note 5 screen went blank, won’t charge

Problem: Went to plug in power cord to charge device, screen went blank and turned off. When it came back on there was just system information then it turned off and has not turned back on or wont even take a charge. What can I do?

Troubleshooting: Try pressing and holding the Volume down and Power buttons for 20 seconds to force reboot the phone. If the system crashed, charging isn’t possible. If the device still won’t turn on after doing that, then it’s time you had it checked by a technician. I’m sorry but we cannot continue troubleshooting if there isn’t enough information about the problem.
