Hey! After school yesterday, I was using my phone and everything was fine when all of a sudden it started freezing and lagging and the screen flashed a bit and it went dark. Like, darker and dimmer than it should. I got home went into my room and tried doing a hard reset and my phone would vibrate, show the htc logo on a really dim/dark screen, and then turn off again. I know it wasn't dead because I had it on my charger
