from android forums: Hear is solution that worked for me with some tech assistance from Verizon.. Power OFF DEVICE... 1. Hold Home Button and press power 2. Screen will show a Android with a triangle with astrick 3. Let Go of Home Button and Power 4. Press Search Button (Far Left Button) 5. A blue menu will show at top of page, scroll to Format Device 6. Select Yes to verify 7. Allow format to complete (Information at bottom of page will go through a few steps) 8. Once Format is complete Blue Menu will show at top again, select Reboot 9. Sometimes phone hangs after rebot and will take a while but if no responce after 5 - 10 minutes, pull the battery and reinsert. (Device usually starts fine after this) Another thing I figured out is that if you are using the new option under Settings/Privacy that says "Back up my data", this feature can cause a number of issues to keep returning even after a hard reset because if your issue was a setting or a app that caused your issue, when you hard resetthe device this feature will restore all the settings and app back on device after restore that will automatically bring issue back. This feature is a nice ideal but until you are sure that everything is compatible it may not be wise to enable this feature because it will make issues go away after hard reset but also cause issue to return shortly after because the system will restore the other files that usually caused the original issue.
