Want the KitKat Camera from Android 4.4?
I think the KK camera uses our auto-focus feature better then the stock LG camera. Plus it has panorama!

Requires:
1) Root access.
2) A filemanager with root access to move files and change permissions (FX, Root Explorer, ES File Manager).
3) MUST download and copy over the LIB files that are in post #5 of the link at the bottom.

Disclaimer:
I had nothing to do with this at all. I'm not responsible if you mess up. I simply wanted to share with the users on this forum. All props go to gulbrillo at XDA.

Instructions:
Download the camera from post #1 and the LIB files in post #5. Unzip and copy the LIB files (not the folder in the ZIP, but the 3 files inside it) to "/system/lib" and set permissions to 644. Copy GoogleCamera.apk to "/system/app" and set permissions to 644. (note: owner/group should be root/root incase they aren't.) The KitKat camera will now show up in your launcher.
