Since I did the update the other day, my phone will just turn off. It does not reboot, it is just off. I have to do the hold the power button and up vol to get it back on. It didn't do it before the update. Anyone else have this problem?
I have not had this happen yet. I would do a master reset. I did a master reset after the update just to make sure I was starting on a clean slate. I will do it again when ICS comes out as well.
Agree with the above on doing a Master Reset.... more than likely VZW tech support will ask you to do that. It will mean setting up your device and downloading all your apps again, but it's better than sitting there waiting for it to shut off again.
I've the same problem. This happened to me twice in past 1 week. This happened even after reset. I have hold power and volume key low to power it up again.
