I've noticed when I dump new sounds or music into their corresponding directories (Notifications, Alarms, Ringtones, etc.) the GNex won't recognize them when I go into Settings to use them. They simply don't show up on the list of available sound effects or ringtones. Rebooting the phone will cause them to show up. Is this normal? Is there a way to force it to re-read the contents without rebooting?
I originally blamed MTP, but I just extracted a sound file from an APK on the phone and put it in the appropriate directory and I still had to reboot in order to see it as a selectable option.
