Android 6.0 Marshmallow includes a fancy new boot animation and if you want to try it out on your Sony Xperia device, then you can download it from the link below. As when trying out any new boot animation, your device will need to be rooted. To install, simply move the “bootanimation.zip” to system/media and set the correct permissions (rw -, r- -, r – -). You can check out the new boot animation in the video below.
