We use SMS interception for system signalling. Is there a mechanism for an app to respond , stop signaling chain? Is there security around that so that a vendor can’t hijack a msg and respond to it
There’s a mechanism where an application can register to receive a message with a certain signature and prevent others from getting it. We have a system of permissions apps are able to declare, enforce, and require to perform certain operations. Things like dial the phone, get to contacts, etc.. But these aren’t things that are baked in the core of the system. An arbitrary app could declare custom permissions.
