Review app permissions by the feature you use

Permission lists are easier to judge when you connect each permission to something you actually do. Start with one app you know well.

1. Write the features you use, such as taking a profile photo or joining an audio call. Identify which access each feature reasonably needs.
2. Open the device's permission controls and review that app. Android can show permissions by app or by permission type; available choices vary by device and version.
3. Remove access that has no current purpose. Where offered and suitable, choose access only while using the app instead of broader background access.
4. Reopen the app and try your essential task. If something stops working, identify the specific missing permission before deciding whether to restore it.

Repeat with another app later. Changing a permission controls future access; do not assume it deletes information the service already received.
