Help my Samsung Galaxy 4 loses its' 3G how can I get it back?
I enjoy downloading songs and texting on my Samsung Galaxy 4, but ocassionally the 3G icon at the top will disappear. This happend today, so I tried removing and re-installing the battery. This didn't help until several minutes later when the 3G at the top of the phone suddenly reappeared. I really don't know if removing and re-installing the battery really resolved my problem, so is there anything I need to do if I lose the 3G again, (which I'm sure I will) Thanks
