did not work for me. I ve tried it on my I9305.
the stock camera apk is named "SamsungCamera.apk."
I moved the gallery2.apk into the system/apps folder, renamed the stock samsungcamera.apk and then
renamed the gallery2.apk to samsungcamera.apk and set the permissions to -rwx. restarting the phone
gave me an "updating applications". however, if I try to start the camera (new CM10.1 icon!), the screen
turns black and I get a "unfortunately, Gallery has stopped."
what did I do wrong or how can one solve that issue?
