heaps. dialer,status bar stuff,notifications. to much to list.
Well , those are stock android 4.4 kitkat .
We still don't know what the update will bring .
I suppose we wait to February end and see what it brings .
My best guess is that sammy will deliver the update , and the only thing that will change will be the android itself since , well , The new TW is not ready and the main new features will come along Galaxy S 5 .
We just hope for a fluid experience and all sammy features packed in a nice update , don't we ?
