I turned my screen on put in my lock pattern and my phone turned off anyone know why this would happen? Couple things you should know. 1) I searched the forums and found nothing about this if there is please give me a link and a mod can close this thread. 2) I had to do a battery pull to turn it back on because it wouldn't respond to the power button. 3) I don't use a task killer. 4) This has never happened to me before. 5) The battery had 51% power left. 6) I want to know if I should be worried or its something that happens often? 7) I have had my Eris since January 06 so the 30 days deal is out the window. I would like to thank anyone with any helpful information in advance.
