In Settings > Apps > Special app access, you can adjust these settings:
- Usage access: Control which apps have access to data about your app usage (what other apps you're using and how often, your carrier, language settings, and other details).
- Unrestricted data: Allow certain apps to use background data even when Data Saver is on. Learn more.
You can also control whether apps have access to features such as Picture-in-picture, Battery optimization, and Do Not Disturb. In general, you shouldn’t need to adjust these.
