Its beautiful and Fast. But few lil bug also. Should work on all (JB/4.1+) roms, but if not, you can simply install as it installs the camera as a seperate user apk.
-The camera runs fine.
-Front-facing camera toggle.
-Swipe to open settings.
-Swipe to open gallery, which asks which gallery app you want to launch.
-Touch to focus toggle.
-Flash mode toggle.
-Shutter sound toggle.
What doesn't work
-Double-flick wrist gesture to launch the camera anytime.
-Panorama mode currently crashes - But working for me in S4 sometimes
-HDR mode is disabled and cannot be enabled.
-Slow-motion mode is disabled and cannot be enabled.
Note: Unfortunately I am on ICS now. So I have tested the same on my S4. Its working great.
