Summary
App can keep its while in use permission forever even if it is in background.

In bindAndGetCallIdentification of CallScreeningServiceHelper.java, there is a possible way to maintain a while-in-use permission in the background due to a permissions bypass. This could lead to local escalation of privilege with no additional execution privileges needed. User interaction is needed for exploitation.
