Oh great. This was a problem with the DroidX. I do not want this problem again! Have not had it happen to me though. Most likely it will happen with a 3rd party app to because it just accesses the phone's camera. If it were me, I'd take it back.
Same Problem Droid 4. Error message is "Camera is unable initialize". I'm avoiding the nasty likelihood of a factory reset. Rebooted, cleared partition cache as well. No luck.
