I'm rooted and using the stock ROM. While sitting at my computer, phone next to me with screen off, out of the corner of my eye I noticed the phones screen come on then very quickly go off, probably less than 2 secs., watched it for awhile and it did the same thing again...very quick on/off of the screen. Doesn't appear to be on any time schedule it just does it. What ever could this be? I havent been able to find any posts similar except maybe random reboots but this isn't it. It could be after getting a text, using ChompSMS with the "screen on from sleep" option.....but who knows, anyone with similar issue?
