I got a strange problem with the One, I put it into a clear water tie bag, in order to prevent the screen and the plastic stick together I put a matte screen protector on the phone, everything seems to work except the back and home buttons does not function ! I then replaced the protector with the bottom section cut off exposing the two control, but still the same problem, without the protector all worked fine ! I don't have this problem with other phone, there is something to do with those controls which are not part of the touch screen, any comment ?
