Splash Screen

In Android-based phones, the splash screen is the first image on the phone's display when it turns on. It is followed by the boot animation, which is typically a short animation accompanied by sound. In contrast, the splash screen is a single static image and is a somewhat permanent part of the phone's internal memory in the sense that flashing a custom ROM doesn't overwrite the splash screen. The splash screen can be customized once the device is rooted and the bootloader is unlocked.
