Hi All, I have 3 Galaxy S2 phones from sprint and they all recently updated. When I try to connect them to a pc to transfer files it pops up "Not a recognized USB device". Before the upgrade they would automatically pop up as a drive on the machine. I called Sprint and they could do nothing. I called Samsung and they transferred me to someone they said would look into it and then left me on hold for a half hour. Anybody else seeing this issue..Thanks
