I'm on an unrooted Droid X with 2.3.x. Camera keeps closing with a short prompt that says, "Oops, cannot open camera. Please try again later." Help? I hope this isn't a problem with the hardware. Just a small software glitch.
Take battery out, and sd card, reinsert both, turn on. This fixed a camera crash problem with my friend's Evo.
Uh the SD Card does nothing and a battery pull is a bad idea for an EXT4 filesystem.. But it's the reboot that worked.
He tried rebooting before that and it didn't work. I googled online and they said to do that, it worked. It was something about mounting the SD card, I can't really remember.
