My camera stopped working at the worst time just when I needed to take some pics at a dinner today. Has anyone encountered a "Camera Failed" message after opening the Camera application? I tried rebooting many times (at least 5-6 times) hoping it was a software glitch, but would not go away. I was testing the GPS navigation (using Google Maps) and my battery drained from 60% to 30% in 20 mins!! Does using navigation or low battery charge screw up the camera? I was sure it was a HW defect thinking I had to return the unit, but when I got home, and plugged into wall charger for a few minutes, I found that camera started working again.
