Anyone experience this problem. It isn't horrible, it's just annoying. Anytime i activate my phone from snooze, i use swipe to unlock. once swiped, my homescreen pops up and in a second, a white flash will pop up quickly and be gone. It's not the whole screen, only a weird shaped pattern usually in the upper portion. I have some widget on there; the samsung time (just the digital time) / beautiful widgets 5 day forecast and some folders on my homescreen. like i said, it's not the end of the world, but if i could make it go away, i'd be much happier.
