Happened yesterday, and happened again today. My screen won't rotate until I turn my phone off and on again. I read this in another forum and they said turning it on and off solves, but to me, that is not the answer.
Also, haven't had this problem the past two days, but I am not receiving all texts from my daughter, who is currently in college in Ohio. She has the Thunderbolt. BUT, I am receiving her text notifications, (thats how I know she sent me something)
