Whole SystemUI is new, camera app is new, apps are new, keyboard is new, browser looks different too, InCallUI is different, AOD is interactive finally, 3rd party notifications work too, notification design is also new, there is performance mode like in MIUI that gives Your device extra boost, fingerprint scanner works a lot faster and finally it's crazily accurate with only one fingerprint scan.
