The automatic shutdown is a common problem to the Samsung Galaxy Note 2, although the problem is vague in a sense that each case may be caused by different factors. We’ve received a lot of emails from our readers regarding this issue and it’s about time we’ll answer some of the questions related to this problem.
Not enough battery to power the device.
Loose battery connection.
Too many apps running.
An app has gone rogue.
Basically, this post will revolve around the five possible causes mentioned above.
Not enough battery
Naturally, when the battery runs out of power, the device shuts down with or without you knowing about it. When this problem happens to you, the very first thing you should look into is the power source–yes, the battery.
Try to turn the device on.
If the screen won’t flicker, it could mean the battery is totally drained.
Insert the charger and let it charge your phone for a few minutes.
Try to turn the device on again.
If this time the screen flickers and the device comes on, then you shouldn’t worry because it’s just a drained battery issue.
Just continue charging the device until it says it’s full.
Loose battery connection
After recharging the device for a few minutes and it won’t power on, it’s time you check the physical connection.
Pop the back panel open and remove the battery.
Check the connectors if they’re bent.
If they were bent, use a tweezers to re-align them and reinsert the battery.
Turn the device on to see if it works.
If the connectors weren’t bent, clean the battery connectors with a dry cloth.
Reinsert the battery and see if the device comes on.
After doing all these and phone’s still dead, there could be a problem with the battery.
If you can borrow or buy a new battery, that would be better.
This problem could be caused by a busted charger; maybe the battery was drained out but the charger failed to charge it.
Too many apps running
If the Galaxy Note 2 turns off automatically but comes on after you pressed the power button, there could be a little problem with the software. There were many users who reported that the cause of the random reboots of their devices were apps that were running in the background.
Go to the Home screen.
Press and hold the Home button until Recent Apps screen appears.
Swipe each app you could find to close them. Doing this will only close the apps that were recently been used but not all.
Go to Settings.
Swipe to Running tab.
Tap each third-party app you can find and force close them.
It may take a little while to complete this procedure but you’re not only preventing the automatic shutdown problem, you’re making your Galaxy Note 2 run a little faster. It’s worth your time and effort, for sure.
An app has gone rogue
If the random shutdown problem happened after you installed a specific app, it could be that it is the one causing the problem. Perhaps it’s incompatible with the current version of Android that’s running on your phone or simply having some issues with the TouchWiz UI…anything could happen. If this was case, here’s what you need to do:
Recall which app you installed prior to the problem.
Go to Settings, then Application Manager.
Find the app and tap on it.
Try to disable it first and see if the reboot still occurs.
If it does, clear the app’s cache and data and see if the problem persists.
If it still does, there’s no other option but to uninstall it. (You could also file a report to the developer of the app.)
For this case, there is probably no solution. But you can try the factory reset and reinstall the app to see if it works after that, although there’s no guarantee. And we’re not sure if you have the time to back everything up on your device because every bit of data will be deleted once you do the factory reset. So, beware!
If all else fail, it could be a hardware problem and the best thing to do is to have an appointment with an authorized technician or your provider and have the phone checked. You can always request for a replacement especially when you’re on a plan.
There’s no point in troubleshooting obvious hardware problems because you may even end up not being able to claim warranty if you go a little further. Of course, there are other risks involved.
