App Permission Manager auf Huawei
EMUI groups app permissions by function instead of only by app. That means you can check in one place which apps currently have access to the camera, microphone, location or contacts, rather than opening every app individually.
This view is useful after installing several new apps, or when you notice unexpected activity such as the camera indicator appearing without an obvious reason. Sorting by function also helps you spot apps that were granted access during setup but never actually need it for their core purpose.
To open the manager, go to Open the settings ➔ Tap on Apps ➔ Tap on Apps ➔ Open the menu ➔ Tap on App permissions ➔ Choose a function. Selecting a function like Camera or Microphone shows every app with that permission and lets you switch access on or off directly.
Turning off a permission here only affects that specific function. Other permissions the app holds stay untouched, so features unrelated to the disabled access continue working normally.
If an app stops working correctly after you revoke a permission, it usually needs that access for a core feature, not just background collection. In that case, re-enabling the permission for that single app is faster than resetting all app permissions.
