I've got the latest 4.1 (update 1a). When I restart the phone it doesn't see the external SD card. If I go to 'Storage', the 'mount' option is disabled. It behaves as if there is no sd card inside. The only way to fix is to remove the back cover, remove the sd and insert it again. At that point the phone mounts it automatically. The problem appears again after restart. Any permanent fix?
Well, reinserting it is a perma fix. Maybe you have dropped your phone and it got moved or your sd card holder is a bit dusty.
