I have searched the forums and found similar problems, but my symptoms are somewhat different so I thought I would ask my question anyway. I have a Moto Droid running v2.1 update 1, not rooted. Today, my phone went silent for incoming calls that use the default ringtone only. Any contacts that have a specific ringtone set still work. Notifications, all other audio still works. When I go to Settings -> Sound and Display and open the menu for setting a default ringtone, nothing is selected. Even after I select something, exit the menu, and go back, there is still no ringtone selected. I have rebooted, uninstalled apps, removed the battery, everything I could think of. But still, the default ringtone menu comes up with nothing selected. I can listen to every one of the ringtones while in the menu, but nothing remains selected when I exit. Any thoughts other than resetting the phone?? Thanks.
