I connected my phone to my PC through a USB cord and went to change my USB settings to media sync, but when I went to go to my USB settings, it wouldn't let me enter and gave me the message of "The application Media sync (process com.samsung.mtp) has stopped unexpectedly. Please try again." with the only option of force close and when I press that it takes me back into "main" settings screen. I tried unmounting my sd card, taking it out and putting it back in. I tried updating my phone but that didn't work either. I have never had this happen to my phone. It always worked fine when I went to change my USB settings. Any help or suggestions?
