I am a problem with my Samsung Galaxy S3. There will be a time when the phone will shut off, and I won't be able to turn it on whatever I do (e.g. Pressing the power, home, or volume buttons). However, I tried stuff and this came to be a temporary solution. I would remove the battery from the phone for a few seconds and put it back again. Then I would plug in the phone and it would work again.
Nonetheless, it is only a temporary solution and the phone may turn off again sometime.
Can someone identify the problem?
