Module reference
Treat system behavior as a few modules instead of a confusing list of toggles. When you know which module you are touching, changes feel safer and more predictable.
| Module | What it controls | Small, safe review |
|---|---|---|
| Permissions | Which apps may access device features like location, camera, microphone, notifications. | Start with rarely used apps. Restrict access that does not match a feature you use. |
| Notifications | Which apps can interrupt you and how those alerts appear. | Keep real-time alerts for a small set. Quiet informational apps. |
| Background activity | What apps may run or refresh when you are not actively using them. | Focus on apps you rarely open. Prefer defaults for core system services. |
Quick checklist
- Pick one module to review. Avoid changing multiple modules at once.
- Make one change, then use the phone normally for a bit.
- If unsure, keep the current setting and revisit later with more context.
