LWP+

2.03

LWP+ is an app for Android that lets users set their own wallpapers and background colors, overriding the OS and its preferences. Read more about LWP+  

Starting with Android 8.1 the operating system chooses the colors by using the wallpaper as a base. Most of the time, it’s OK, but sometimes users might want to choose their color and wallpaper. This can be done with LWP+.
 
With the help of the application users can choose the colors they want, which means that for example, you can have a dark themed notification drawer. Also, the application can be used to set up a double-tap-to-lock device (if you have root access), to choose which colors to request from the OS, and to show a gif animation.
