I've had this issue for a couple of months now and haven't been able to figure the cause or the fix. Perhaps I dropped my TB too many time?
Sometimes when I try to dial out, there is a minute to 3 minute delay in dialing. I would get frustrated and hit the button again and after a couple of minutes the phone would dial the number or person 2 times.
Stock, stock dialer, and I've tried the battery pull and restart. I've never wiped the phone. I don't have the random restart issue, but do have that damn short battery life.
Any advice would be appreciated! Thanks!
