I just got the Droid X.
I installed a handful of free apps and chose a factory ringtone.
The phone was working fine for a while, but suddenly has just stopped ringing.
I have turned the system volume to loudest setting.
I have used the side toggle bars as well.
Silent mode is "OFF".
Sound is "ON" on the menu before shut down.
I have turned it off, re-selected ringtones and reset.
Please help. I am missing very important phone calls.
My phone vibrates only.
Also, ALL of my other audible notifications work fine.
Email, text, etc... all ring with the factory setting I chose.
