SOST

I want to delete the App "Version R-initial

com.android.cellbroadcastreceiver.module

I don't need a emergency broadcast app.
And i don't like the Fakt, i can't disable the SMS and comunication to other devices in surroundig area.
How can i delete this App?

SOST Do not try to delete system apps. It's not possible and you will break things.

If you truly want to not talk to cell towers, the only way to actually do that is to use airplane mode.

SOST You can disable receiving emergency broadcasts in Settings. This is a core OS component. It's strongly recommended not to mess with permissions for core system components or to disable them. It's strange that they're even shown in Settings and that may change.

Hey, you could probably disable the app or use adb if disable the app inst an option.

BrianHolmes but there isn't a way to completely uninstall a system app.

The Problem is, this App can send SMS and talk to other devices around your Cellphone without you know. And you can't change it or delete it.
And this App is only for emergency broadcast, not the normal connections.

I don't want this App. How i delete it?

GrapheneOS

SOST No, it cannot do those things. It's an open source component of the OS and you can see how it uses the permissions it has granted. It can't start doing things it wasn't written to do. You can see it as an app because it was implemented as one, but it just as easily could have been part of system_server and you wouldn't see it as an app.
