During the time when Android device is starting (“booting”), it displays simple animation on the screen – this is called boot animation (sometimes written together as “bootanimation”). On the background, Android is loading everything needed for the proper functioning and once everything is loaded, it will switch from boot animation to your home screen.

The boot animation is usually prepared by the manufacturer of the device and contains their logo. If you are using Android device for digital signage, it might be a good idea to replace the original boot animation with something more professional-looking. This is possible only on rooted devices, otherwise the original boot animation can’t be replaced.
