CellBroadcastReceiver overlay.

Overlays work by mapping resources defined in the overlay package to resources defined in the target package. When an app attempts to resolve the value of a resource in the target package, the value of the overlay resource the target resource is mapped to is returned instead.

The CellBroadcastReceiver app is a default system app that handles emergency and nonemergency alerts (such as amber and presidential alerts) and presents the information to end users based on carrier and regional regulations.
