My phone keeps turning off
My phone turned off by itself and then didn't turn back on. I removed the battery and let it sit for a while and then put it back on and still didn't turn on. After morr than one hour and half it turned on but later in thr night it did the same. Then I did a Reset using Recovery Booting. The next day it turned off again but after 10 minutes Iit turned on back and now it did the same and doesn't turn on. It turns of till I see the Samsung logo and then it turns off and on again just to see the Samsung logo. And when it worked after I did the reset I went to the software upgrade and it said that my opersting system has been modificated in an unauthorizate way. Does anyone knows what the problem might be?
