Is dust under the screen even though it has been a few months grounds for an HTC factory defect/ replacement? What about dead pixels? I feel like dust is definitely something to qualify a phone for a replacement, unless all phones have the same problem in which case no one should want this phone anymore. Dead pixels I am not so sure about because they can be caused by a user, but can also appear randomly with no blame attributed to the user. What do you guys think/ What is your experience with HTC/Sprint?
