The camera sometimes has problems focusing. Menus need an ""exit menu"" option and menu should be gone when you leave and restart app (currently you have to kill camera via task management to exit menu). Date/Time overlay needs invert option (currently upside down in top left on photos  when camera used by lefthander). Camera appears to keep photographing legs and floor whilst positioning device and accidentally enters menus  making it difficult to use in practical or live action scenarios.
