I've had my Droid for several months and have been extremely happy with it. But recently the phone has stopped ringing when called. The screen will change to the incoming call screen with the accept or reject swipe buttons, but the phone will not make a sounds, even with the ring volume set to max. I've heard about the problem with the phone only outputting sound to the headphones, so I've called my cell with headphones in, and even then there is no sound.
I've tried changing the ringtone by going to the Settings->Sound & Display->Phone Ringtone, but it looks like the phone never remembers what I select, because if I select a ringtone, hit OK, and then immediately open the Phone Ringtone setting again, no ringtone is selected, not even the Silent option.
I have turned the phone off and removed the battery several times and uninstalled some third-party apps like LauncherPro and AudioManager thinking they might be the cause. But short of doing a Factory Reset, I'm not sure what else to do. Has anyone seen this before or know a solution? Thanks for any help you can give.
