On my Galaxy S3 running latest Android 4.3, TimeLapse (paid version) crashes after some time with an error "Sorry, camera could not be initialised".
I set the phone to factory defaults and flashed latest available Android 4.1 firmware. Now TimeLapse runs without errors. But I only got 50 photos within an hour with interval set to 10 sec. Photos are taken irregularly sometimes with up to 3 minutes between two shots.
I use external power and the screen is off.
