Works just fine on CyanogenOS 12.1 (Lollipop 5.1.1). I regret I can only rate this 4 stars though, because the snowflakes don't look realistic enough for me...
Not working Only blank screen app not opening.moto e 1st gen lollipop 5.1 device
Cm Very beautiful thank you if not the best snow I like using custom images
Ok this is GREAT!!! I always like finding the best. And this app is the best. You can customize the background and in my case it is always snowing in NYC. The snow is even customizable. Thanks. You made my day!!
Application performance and battery saving have been improved
Added snow transparency settings
Image cropping functionality has been improved. Background can have any size now
Fixed loading custom image issue on Android 4.4 and up
