Hi ! I just created Xperia Z2 Boot Animation for MDPI device !
What makes it different is this bootanimation have sound,and medium quality images. Also, i added "powered by android" branding logo on splash screen to make our phone looks like a newer handset
Since it medium quality images, the size increase to 4.83 MB
