Changed battery and now phone vibrates constantly, why?
I just replaced my HTC One M8's battery and charging port. When I put the phone back together the screen remains blank. I can feel the device responding to touch but the backlight does not function now. I disabled the phone 2 more times thinking I had missed a connection but without good luck. The bad luck came on the 3rd attempt,, when I reconnected the battery lead to the battery the phone vibrates, constantly. I assume now there's a short in that circuit. Any ideas?
Ist dies eine gute Frage?
