The coolest feature is shown off in the video. Though it’s a bit useless, it looks absolutely amazing. Touching the lockscreen creates the ripples, like every other build, but touching the lockscreen with the S Pen creates an ink splatter that fades into the water.
You also get customizable notification toggles, a removable brightness slider in the notification panel, a Multi-View toggle, new Swype-like input in the Samsung keyboard, a Group Cast app, and a smoother browser. A great new update that will hopefully launch soon.
If you’re going to flash this, note (heh) that it is only for the international model (N7100). Also consider that this is a pre-release build and that it may be buggy. It is also not supported by Samsung, so do this at your own risk. Happy flashing!
