Android Nougat vs Android 6.0 Marshmallow Walkthrough: What’s New

Different Wallpaper for Lockscreen & Homescreen

With stock Android we only get one choice for the wallpaper on our smartphone. Whatever image selected will be on both the homescreen, and the lockscreen. Well, unless you're on Android 7.0 or newer.

Google now allows a different photo for the homescreen and lockscreen, if you'd like. This is a feature we've seen on Samsung and LG phones for years, and now all Android devices have it.
