My phone was working perfectly. Then all of a sudden it started powering down and on by itself. It does not stay on long enough for me to look at any settings. I let the battery drain completely out and it still had the issue, I also physically took the battery out for over an hour and I still had the issue. I tried taking the SD card out and the issue is still happening. It's been over 24 hours now and I cannot use my phone. This is beyond frustrating and annoying. Please advise. The phone is less than 6 mos old. I did not drop it and it didn't get in any water.
