I've have my phone for a week now and love it but I've had to restart it over 10 times already. three different times I've been in the camera mode and took a panoramic photo and it got stuck and all the other features and app worked but when going into camera mode it was stuck. And twice I tried to go into camera mode and it wouldn't work. And a few time it had no service when I was in the same spot a it had great service a minute before. A few times it said I have no SIM card installed by the icon at the top of the phone notification bar. One time last night it even had a pup up the said PUC not installed or something like that. Any solutions ?
