I've been experiencing a weird issue since going from SS 4.0 to SS 4.1. I seem to lose the use of my 'home' button after I enable & disable USB file transfer. I hook my phone up via the USB cable and then enable USB transfer. I then transfer my .apk file on my phone and turn off USB file transfer. Once I do this, my home button no longer does anything. I do get the haptic feedback, however, it doesn't do anything. All of the other buttons work just fine though, and the only way I've been able to solve my problem is to reboot the phone. Any suggestions?
