Since the March 22 update, my screen wakes at seemingly random times. The wakes don't seem to correlate with any event (text, call, etc). I saw the discussion about wakes caused by incoming text messages (Samsung asked Verizon to trigger wake to increase counters, they're looking for a better solution) but I'm thinking that my problem is not related to that since mine wakes frequently (20 times an hour) even when nothing is happening with my phone. I only get 3-4 text messages per WEEK and 3-4 phone calls per WEEK so it's pretty clear that the 20 screen wakes per HOUR aren't caused by calls or texts.
How do I find out what's causing the screen to wake? It started with the March 22 update.
