Whenever i use my cam, it says there's another application running and i should close it in order to use my cam. As far as i know, there's no app running and i tried changing the camdriver. Help would really appreciated. :]
EDITED:
I manages to have my camera working again by doing this method
Remove the sim card and push the air (from mouth)into the Inner camera. It's kinda weird but it works for me. :] I hope this help for people that having the same problem.
