I had the dreaded 'Media Server' battery drain over the last few days so reformatted my SD card and then copied over the files again to the card. Now I cannot change the ringtone. When I try I get an option to choose the app to locate a music file on the SD card which it does, but the ringtone does not change. Looking at the forums it seems I should be choosing 'Media Storage' from the selected apps but this is not showing up. Any ideas would be gratefully received.
