Samsung released a new version of TouchWiz to a beta testing group a while back, but we haven't really gotten a good look at what the new build has to offer... until now. HD Blog has put together a comprehensive walkthrough of the new built. There are quite a few changes to the UI with flatter graphic elements, tweaks to folders, notification panel, quick toggles, widget panel, settings and much more. Samsung has also included contextual menus for apps which appear when you swipe up on an app icon. There's no guarantee, but there's a good chance that this beta build of TouchWiz will be finalized and installed on the Samsung Galaxy Note 7 when it launches in August.
