I really hope someone here can help because I have a very frustrating issue. I've started to notice that my galaxy starts acting up and in order to get it to function properly, I have to completely restart it! By acting up, I mean, it cannot find signal when I start up the navigation, cannot find signal for data connection, does not go into sleep mode and stays on continuosly. This is extremely frustrating since I end up restarting my phone at least once or twice daily! Please someone help!
