Now that the Android M developer preview is out in the wild, we’ve got the Android faithful flashing Android M in the forums and digging it apart for all the nitty gritty goodies.
Among them, without fail, is a collection of the default wallpapers. Unfortunately, (at this point) there is only 1 new wallpaper found in Android M. The lone new wallpaper appears to be a picture of earth taken from space – just another reason to think that Android M won’t be called Marshmallow but instead will be called Android Milky Way.
This app also contains the other 10 default wallpapers found on the developer preview of android M.
It is completely free, no ads or something like that.
