Fully working camera app for AOSP roms (maybe others) from Hauwey!!
Having paranoidandroid rom on my gs3 was great..but the camera app obviously was lacking.
I searched and tried many apps to find the better solution...most was force closing,stock one just had minor settings
So I tried this that comes from Hauwey and so far,i think its the best I found.Try it out and let me know.
simply install it like any other .apk app
Oh, it simply installs alongside with the old camera app,so no harm done if you don't like it,simply uninstall it.
