1. Batch permission management: Go to Settings > Security & privacy > Privacy controls > Permission manager — select a permission type (e.g., Location, Camera, Microphone);
2. Toggle permissions on/off for individual apps (options: Allow only while using the app, Ask every time, or Don’t allow);
3. Single app management: Go to Settings > Apps > All apps > [App Name] > Permissions — toggle individual permission on/off (options: Allow only while using the app, Ask every time, or Don’t allow).
Tip: Disable unnecessary permissions (e.g., a calculator app does not need Camera/Location access) to protect privacy and reduce battery usage.
