lately ive had to be resetting the phone daily to sent texts out. They wont send till i restart the phone. Ive never had to reset my phone so much before ever(iphone4) if my percentage drops below 15% and i take a picture with the flash the phone turns off. sometimes i wont get texts till 3-4 hrs later. i seem to have to close apps to open them sometimes to get to work. time to swap it for a new one?
