Nope, this one did it too! I'm starting to think there's something in my truck making it do it... I had it for 2 days around the house and it was fine, I got in my truck last night and it did it! (I'm a truck driver) so I'm starting to think there's something in my truck causing them to act that way! 3 evo's all doing same thing, I don't know... Any ideas, please let me know, called Sprint, they said go to a Sprint store and swap again!
