i watched this video before buying my htc one. and the first thing i did was to check my phone for this kind of issues. but i have non of these bad stuff. is this an international problem? maybe iam using a second revision or something? or iam lucky. but not sure if it is a problem let me tell u something. while iam making a call. lets say i will end the call, i move phone from my head, but it is still screen is black, i have to press power button to wake the screen awake..i think thi is an issue. just my phone material quality isnt bad as in the video.
