About 2 months ago my phone started acting up when sending messages and would either tell me there was a network problem or it would just freeze, after about 15 minutes of me trying to send a message it froze so i did a battery restart, now every time i go to send a text the phone shows the opening screen and turns itself off.In addition i can't receive messages either. Everything else on the phone works fine. It has been happening for some time and i haven't really had the time to take it in and get a new one. So i thought i would post here and ask if anyone knew what was up.Thanks!
