Yesterday I obtained 2 white 900s. One is having the purple-ish tint issue. However, there is another issue that both devices are having. When waking the phone from sleep, the screen glitches for a fraction of a second. Usually this glitch is a set of white lines that flash on the screen before the lock screen appears on the display. It has popped up a couple of times in transitions between screens as well. I have noticed this on both devices. Anyone else notice this?
