Samsung Galaxy S4 Switches Off Does Not Restart Issue

S4 Switches Off Does Not Restart

Problem: My phone was working perfect this morning then suddenly switched off and would not restart.  I took the battery out the back and put it back in and it came up with Android initialising then when blank again.  It has not powered up still 3 hours later.  I have took the battery out again and still nothing however when I press the button on the side to switch it on it buzzes but nothing happens.  Can you please advice me?  Many thanks.

Solution: There are a couple of factors that we should check for this type of issue. The first thing to do is to check if the issue is caused by a weak battery. Try connecting the phone to a wall charger and let it charge for at least 20 minutes. With the charger still connected try to turn on the phone. If the issue does not occur then it’s possible that it could be caused by the battery. If this is the case then you should get a new battery.

Another possible reason why this problem exists is because of a glitch in the phone data or software.

To troubleshoot this scenario you need to take out the battery and microSD card ( if you have one attached). Press and old the power button for at least a minute then reinsert just the battery. Turn on your phone in recovery mode then wipe its cache partition. This will delete the temporary data in your device. Restart your phone then check if the problem still occurs.

If at this point the issue still occurs then you will need to backup your phone data then do a factory reset. The best way to do a factory reset is through the recovery mode. If you are unable to access this mode then the issue could already be hardware related. If this is the case then you should have you phone checked at an authorized service center.
