GOOD:
Overall speed improvement (apps open faster and transitions are smoother)
Touchwiz redraw issue seems to be fixed
Contacts, Phone, Messaging and Camera app loads times reduced
Wifi seems faster (sounds stupid and inconclusive, but the speed seems faster)
When swiping away apps in recent apps, animation much faster
Home button delay (when S-voice off) seems faster
Gallery loading time faster
Slightly better RAM usage/management
Almost no redraws of home (action launcher and touchwiz) and home loads slightly faster.
BAD:
While in portrait in Camera, recent apps is still in landscape.
Swiftkey default keyboard issue (resetting after reboot) still present
Second APK exploits still unpatched.
