Late yesterday I experienced a problem where my phone would shut off without me making it do so. I then proceeded to turn it back on and it went through the loading screen, which confused me because I have the fast boot always on. It went through the AT&T logo and HTC logo screen then went to the stock HTC One lock screen. I thought it was maybe just a minor error but when I went to unlock my phone it asked me for my Encryption password; I have never set an encryption password before. I then took it to AT&T and they had to factory reset my phone. Needless to say I lost everything. So last night I re-downloaded my apps and synced up all of my accounts I use. There was no problem until this morning as I am waiting to enter my school. I was browsing twitter and my phone randomly went black. Then it went back to the HTC loading page. I then turned it back off just as before. As it came back on it everything seemed to be fine. I then went to refresh my BlinkFeed and an error message popped up and said something I can only equate to saying the operating system had failed. Before I could click "OK" it shut off and went to a very strange screen. It wasn't producing any light from the screen and it looked sort of like how a calculator looks if look at it from an angle. It seemed to have panels of the screen on it. I then held down the power button and it came back on but is now stuck on the HTC Quietly Brilliant screen. It keeps getting warmer, and when I hold down the lock button the home button and back button start the flash. I have no idea what is going on but it is very annoying.
