I have what seems to be a constant problem on my Vibrant. I seem to constantly have problems receiving text messages. I only find out that I have missed messages when I eventually do receive a message from a friend demanding to know why I had not answered their previous messages. It does it seemingly randomly and can occur in the middle of conversations even when I haven't loaded any new apps or done anything else that seems like it should have caused the problem. Any help would be greatly appreciated.
