It is important !!!
Because not all devices support OpenGL ES 2.0, we recommend before purchasing of this model of live wallpaper, to install and test the free version on your device. Type in the search of application "Test Animation LWP", install and test on your device, if the test application runs correctly you can safely buy "Mountain River LWP", but if the test application works with complaints (perhaps green blinking in the top part of the screen) or in general it does not start please refrain from purchasing.
