On disc drives, defragmenting migrates the data into the center of the disc (and also aligns all the same programs together) for faster reading. It's not such of an issue with SSDs, because the device can read anywhere on the SSD at the same speed. Where a disc drive needs to spin the disc faster to read the information that physically is stored on the outer edge of the disc.

Android devices use solid-state drives, so this isn't required.
