I think it started in 5.1(currently on 5.2 with patches) but I have not been able to mount my SD to any PC. It always seems to reboot the phone. Oddly though the reboot time seems much quicker then a normal reboot. I've searched this forum but haven't been able to find anything, I assume I'm doing something wrong since I figure mounting the SD card and transferring files is a pretty common use case for users. Any help would be appreciated, thanks.
