I've had my phone for about two weeks now with no issues. I have my phone set to "charge only" when it's plugged in via USB. About two days ago, the phone started to automatically change itself to disk drive mode and mount the SD card. I've uninstalled all my newer programs and gone through all of their settings to try and find something that is trying to mount my SD card. Can't seem to find it. I like to use the tethering option too and I can't now because of this. Any help would be appreciated.
