2-3 times a day, while doing many different things so I am sure it's not 1 app, my phone will freeze up for 15-30 seconds. Neither the buttons nor the touch screen works. If I wait, it will work again or if I am in the middle of something if I tap the power button and then turn the phone back on it works again. Any thoughts? Also, why does the sync notification (arrows chasing each other in a circle) appear in the status bar randomly when I am not doing anything or when something is not downloading? Thanks. Overall, I love this phone. No battery issues whatsoever. Just plug it in at night and I make it from 6AM to 11PM with the battery notification just turning yellow. Good stuff.
