Note 4 Shuts Off Restarts On Its Own
Problem: my Android Samsung Note 4 will shut off and turn back on but will continue to shut itself off. it will not allow me to reboot. how can I fix it? The only way I can get on here and use my phone is to have it plugged into my charger at all times.
Solution: One of the first things that comes into mind when the phone doesn’t work if it isn’t connected to its charger is a faulty battery. This usually happens when the battery can’t hold sufficient charge anymore. Try using a new battery on your phone and see if this fixes the problem.
Another thing you should look into is that the phone software is causing this problem. Sometimes glitches and errors that occur in the software will result in this issue. To check if this is what’s happening right now you need to backup your phone data then do a factory reset.
If the above steps fail to resolve the problem then I suggest you have your phone checked at a service center as this could already be a hardware issue.
Note 4 Turns Off When Opening App
Problem: every once in awhile i’ll open an app and the phone will just turn off. sometimes it will restart. but recently it won’t even come on. it’ll just keep restarting even after i took the battery out and did the soft restart. the galaxy note 4 screen will come up, then the samsung screen, then phone company then it will just cut off and start restarting non stop only going to the note 4 screen. after a while it will just say it is dead
Solution: What you need to do first in this case is to check if the issue is caused by the phone software. To do this you should start your phone in recovery mode. This is a separate environment from the main operating software of the phone. Try to observe if the phone restart while in recovery mode. If it doesn’t then the problem could be software related. You will need to do a factory reset to resolve this problem. Take note that the reset will erase all of your phone data so make sure to have a backup copy before proceeding with this step.
Another factor you should look into is if the problem is caused by insufficient power. Try connecting the phone to a charger and see if the issue occurs.You should also try replacing the phone battery with a new one to check if the battery is causing the problem.
If the above steps fail to resolve the issue then it could be caused by a faulty hardware component. I suggest you have your phone checked at a service center if this is the case.
Note 4 Cannot Be Charged with Wall Charger
Problem: I have two new batteries. I changed the USB port on the phone. I have tried three different cords and two different chargers. No success. Battery cannot be charged by plugging the charger in the wall. Phone can be charged by the USB connection on the phone but only for two minutes. Quickly shows 100 % charged when in fact it is some other percentage which it shows if you disconnect it from the PC. Also, it does powers up if you connect into the computer…does not stay shut off. Any help you can provide would be very useful.
Solution: What you need to do first in this case is to use another mobile device and check if the charger and power cords are indeed working. If the other device charges normally with the chargers that don’t work in your phone then it’s safe to say that the problem is with the phone itself.
Since you already tried different batteries and even replaced the USB port I suggest you try doing a factory reset next to check if this issue is caused by a glitch in the phone software. Make sure to backup your phone data before doing this. If the problem still remains then I suggest you have your phone checked at a service center as this looks like a hardware related issue already.
Note 4 Shuts Off Crashes Randomly
Problem: My phone shuts off even at 75% battery. Sometimes it just crashes and I have to take the battery out to start it. Sometimes even at high battery % it goes off and it doesn’t come on. When I connect the charger it shows 65%(+) battery then comes on. When it shuts of and I put it back on it asks for backup password and does not let me use my fingerprint. Also even at high battery percent it goes of and when I turn it back on it goes to the part where the writing Samsung comes up and them just goes of comes back again to the part where Samsung comes and them it keeps repeating until I take the battery out. Please help i appreciate it.
Solution: In most cases where the phone shuts off on its own the problem is caused by a glitch in the phone software. This is why we will be checking your phone software first. Try wiping the cache partition of your phone from the recovery mode first to take out the temporary data stored in the phone. Sometimes if this data is corrupt issues such as this can occur. Restart your phone then check if the problem still occurs.
One other factor that you should check is if an app you downloaded is causing the problem. For this you need to start the phone in Safe Mode. In this mode only the pre-installed apps are allowed to run while apps you downloaded are disabled. Try to check if the problem still occurs in this mode. If it doesn’t then it is most likely caused by an app. Find out what app this is and uninstall it.
One last software troubleshooting that you can do is a factory reset. Take note that this will erase your phone data so make sure to have a backup copy before proceeding with this step.
Note 4 Restarting After Marshmallow Update
Problem: After firmware update from lollipop to marshmallow, my phone continues to restart, it will power off, then restart. Regardless of the battery level, whether plugged in or on battery. Also, it drains the battery extremely fast, my battery use to work all day, from 6am till the next morning. It now drains in about 2 to 3 hours. Also it use to charge very fastfast, from 30% to 100% in 30 minutes… Now at least 5 hours to charge it. And it runs very slow, lagging. I have wiped the partition, but have NOT yet done a factory reset… I plan on doing this next week once I get home after I backup my phone. Any help would be great.
Solution: The best thing to do in this case since the phone has multiple issues right after the software update is a factory reset. Since you are already planning to do this just make sure to backup your phone data first as it will be erased in the process.
Note 4 Turns Off On Its Own
Problem: My phone turns off when even if i have a high battery charge. When i just open an app or just use it it turns off. and to turn it back on i have to remove the battery and put it back again. If not the phone doesn’t turn or even if i connect it to the charger. I have tried a new battery even it still doesn’t fix the problem. This has been happening for months now and i haven’t been able to fix the problem cause i can’t find any solutions for it. And also my battery doesnt charge all the way up to 100% it gets stuck around 92% and only when i remove the battery and put it back it starts charging from 92% till 100%. Please help me if you can. My phone model number is SM-N910L
Solution: Try checking if the issue occurs when your phone is in Safe Mode. If it doesn’t occur in this mode then the problem could be caused by an app installed in your phone. Find out what app this is then uninstall it. If the same issue occurs in Safe Mode then I suggest you backup your phone data then do a factory reset.
If the above steps fail to fix the problem then this could already be caused by a faulty component inside your phone. I suggest you have your phone checked at a service center if this is the case.
