So, I upgraded to 2.1 a few months ago. Everything seemed fine. Data works, can connect to my comp (Win 7) to transfer files no prob, bluetooth/wifi/gps all worked well. But about 3 or 4 weeks ago my data turns on and off at random, texts don't go through, and whenever I plug my phone into my computer, when I unplug it, it restarts. If i put it into debug mode and connect it to usb, when I unplug it it restarts. It restarts to the Samsung lading screen over and over and over and over again until I unplug the USB. I am not computer/android guru or anything, but I do know my way around them decently. And nothing I can figure out works. i went into the Sprint store and the guy told me to do a factory reset. I did. Didn't do anything, same problems. Any ideas?
