i have had, and still have, quite a few issues with my HTC one but im very stubborn so ill stick with this phone cause i really love it. I had the issue with the camera, sent it to service and it came with 1 dead pixel. Sent it back and came untouched cause they have minimum 2 dead policy. Argued with them over phone and convinced them to exchange the display. Sent it and came back with 2 dead pixels . Ok now the pixels are visible on white and they dont bother me that much but the screen is not as smooth as the old one. Its hard to explain but the swipe is not feeling the same.... I was reading and seems that smoothness is given by the oleophobic cover which its probably is missing. So my question is .. is there any way to test this. I really want to avoid sending it back to service again.
