This app is 100% free, but you can also buy the premium to remove annoy ads and support the developer.
* This app may not support any third party ROMs and rooted devices, for any malfunction, system crash, or dead lock due to the above reason I can not be able to fix it.
* Some devices' launcher might not support a scrolling wallpaper, therefore you may see the screen only displays the left of wallpaper and it does not scrolls. One substitution would be download and install a third party launcher such as Nova, Go, Apex etc.
* Some devices' launcher do support a scrolling wallpaper but it is not enabled. You may try to look for the configuration such as display or desktop launcher in your setting to enable this feature.
** Samsung's TouchWiz launcher may not support a scrolling wallpaper, and it may cause system crash.
