CellBroadcastService 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 CellBroadcastService service supports CellBroadcast SMS decoding, geofencing for wireless emergency alert (WEA) 3.0, message duplication checks, and broadcasting messages to apps. It's a one-to-many geotargeted and geofenced messaging service designed to deliver messages to multiple mobile phone users, in a defined area, at the same time. The service is defined by the [ETSI](https://www.etsi.org/about) GSM committee, [3GPP](https://www.3gpp.org/about-3gpp), and is a part of the telecommunication standards.

Todas las desinstalaciones listadas aquí afectan solo al usuario actual: la imagen del sistema no se toca y el comando de restauración devuelve la aplicación a partir de la copia que ya está en el aparato. No se descarga nada.

Esto no es el directorio. Aquí se dice qué es un paquete en general; lo que pasa en tu televisor concreto está en la ficha de tu modelo, y esa manda. El mismo paquete puede sobrar en un aparato y sostener la pantalla de inicio en otro.
