What it does
System UI is the part of Android that draws everything around your apps: the status bar, notification shade, quick settings, lock screen, volume and power menus, screenshot tools and the navigation bar. It comes from the Android Open Source Project and every phone maker customizes it, and it starts at boot and runs the whole time the phone is on. The message that System UI has stopped means this process crashed and restarted.
