I wish I could say I've had no problems, but the phone has locked up on me twice since I forced the update the other night. I've normally attributed it to the Fb widget in the past (before the update) and turned it off. I'm trying domething new this time and leaving it on.
The first time it locked up on the home screen. Nothing seemed to make the phone budge so I hit the power button and the backlight went out. The button wouldn't turn the screen back on, but I noticed if I held the screen at a certain angle I could see a faint image. Just as I pulled the battery cover off to do a battery pull, the phone rebooted.
Second time was in GV app. It froze after trying to send a message. I hit the power button and the screen went out. This time after hitting the power button again I got the lock screen. After punching in the code I got a prompt to FC the GV app.
Also just after the update my GPS wanted to stay on so I manually turned it off. But I turned it back on and it hasn't happened again. I've also noticed my phone has been switching to 1x more often than before, but I'm thinking its because of people getting the OTA.
Other than that the phone is great and the battery seems to last a bit longer.
