My 8300 which is pristine, no scratchs or nicks has dust under the screen. This device is in a leather case where it stays. After talking with TOM DONNER in ATT's Warranty Department in South Dakota. He advised me the dust under the screen is not a defect and it will not be replaced. He said dust could not get under the screen unless there is a crack in my device. He told me my device is out of warranty "because it has obviuosly been dropped".
