Hi, i’m using HTC desire 820 for 3 year some day ago my phone screen turn off suddenly (LCD screen is black) after that i couldn’t turn my phone on or even charge my phone (red light doesn’t turn on) i found that i can turn my phone on when my phone battery level change to zero it’s some looping i think that happens suddenly and LCD screen is black ,phone doesn’t work and even doesn’t charge i must wait until battery level change to zero, then phone turn off automatically . after that i can turn my phone on again but again after some hour, screen change to black and again and again i have to wait any help please ??

try hard reset when it happens, could be software problem sounds like phone is just freezing
