Why does my ring tone keep changing back to vibrate?? No matter how I set the ring tone it keeps changing back to vibrate, kind of hard to hear when you aren't holding the phone.
I think I'm having the same problem. It "thinks" it's in normal mode, but it will only vibrate. Any chance you are also running Slacker music player? I swear this problem started about the same time I installed and started using it. The only 'fix' I've found it pulling and returning the battery. Frustrating. Have you heard anything else?
