Why is my htc one 8 screen black
My HTC One M8 has a black screen. the phone rings, I can hear it vibrating when I get a message, but the screen will not light up. Please Help!
Sounds to me from your description of the fault that the screen is faulty and you need to replace it, mind you this is only one of the reasons, there are others. But this is going to be the cheapest to fix I'm thinking
