Videos show Android 5.0.1 running on the Samsung Galaxy Note 4 and Samsung Galaxy Note Edge
For example, with Android 5.0.1, the Display and Wallpaper settings on the Samsung Galaxy Note 4 and Galaxy Note Edge will allow you to select Ambient Display. Pressing the circle icon on the top corner of the phone will display a box showing how much storage is being consumed by content such as images, music, voice, documents and others. And Share with Contacts is a new messaging option that lets you send a long text message, share an original photo with friends, and check the delivery status of a message. The update also adds fast/slow motion video recording and exterminates some bugs.
The features for the Samsung Galaxy Note Edge are the same, outside of the special capabilities for the wrap-around screen.
