I no longer have default (any) ring tones. May have lost something else, too.
One morning Notifications informed me my internal memory was full. Touch screen functions were intermittent. Settings, More, Storage, Applications showed an app had consumed several GB of storage. It was early and I was in a hurry so I don't remember but it seemed to be named something like (verizon?)media(storage?). I cleared (deleted?) it and the phone returned to normal functionality.
However, I do not have ring tone options. Settings, My Device, Sound, Ringtones. When I go to Ringtones, I have give the choice of File Explorer (my app) or Media Storage (Android system) Within Media Storage my only option is Silent. My default Clock Alarms show an Alarm Tones (5) but there is no sound. Interestingly, ring tones associated with phone calls seem to be working but cannot be changed. Am not in Airplane Mode, Volume is at max and Sound is on.
I only used the default ringtones and would like to get them back. SCH I545, Android 4.3
Thank you for your help.
