Every app on your phone asks for permissions: access to your camera, location, contacts, microphone and more. Some requests make sense; others do not. Android gives you full control over these permissions, and checking them takes only a few minutes. This guide explains what each permission means and how to manage them on any modern Android phone.
Key takeaways

- Location, camera and microphone have extra options like Only while using the app and Ask every time.
- Android can automatically remove permissions from apps you have not used for a while.
- You can switch off camera and microphone access for the whole phone in one tap.

Why app permissions matter
Permissions decide what an app can see and do on your phone. A navigation app needs your location; a photo editor needs your photos. But a flashlight or calculator app has no reason to read your contacts or record audio. Reviewing permissions protects your privacy, can improve battery life and reduces the chance of an app misusing your data.
Change permissions for one app
Android Help describes these steps:
- Open Settings and tap Apps.
- Tap the app you want to check. If you do not see it, tap See all apps.
- Tap Permissions.
- Tap a permission and choose Allow or Don’t allow.
See all apps that use a permission
Sometimes it is easier to check one permission at a time, for example to see every app that can use your location. Go to Settings > Security & privacy > Privacy > Permission manager, then choose a type. Common types include:
| Permission | What it allows | Usually needed by |
|---|---|---|
| Location | Your approximate or precise location | Maps, ride-hailing, weather |
| Camera | Taking photos and videos | Camera, video calls, scanners |
| Microphone | Recording audio | Calls, voice notes, voice search |
| Contacts | Reading your contact list | Messaging and calling apps |
| Photos and videos | Access to your media | Galleries, editors, social apps |
| Notifications | Showing alerts | Most apps; turn off for noisy ones |
| Nearby devices | Finding Bluetooth devices | Earbuds, smartwatches |
Understand the permission options
For location, camera and microphone, Android offers more than a simple yes or no:
- All the time (location only): the app can use it even in the background.
- Allow only while using the app: access only while the app is open. This is the best choice for most apps.
- Ask every time: the app must ask each time you open it.
- Don’t allow: no access at all.
Tip: Choose Only while using the app for location in most apps. Only navigation or family-safety apps really need location all the time.
Remove permissions from unused apps
Android can pause apps you have not used for a while and remove their permissions automatically. Open the app’s settings and, under Unused app settings, turn on Pause app activity if unused. This is a simple way to keep old apps from quietly keeping access to your data.
Turn off camera and microphone access for the whole phone
On recent Android versions you can block every app from using the camera or microphone at once. Go to Settings > Security & privacy > Privacy > Privacy controls and switch off Camera access or Microphone access. Many phones also show these switches in Quick Settings. When an app uses the camera or microphone, Android shows a small green indicator at the top of the screen.
A quick monthly checklist
- Check which apps have location all the time and downgrade where possible.
- Review camera and microphone access in Permission manager.
- Remove contacts and SMS access from apps that do not need it.
- Uninstall apps you no longer use.
- Keep Pause app activity if unused turned on.
FAQs
Will an app stop working if I deny a permission?
Only the feature that needs it. For example, a messaging app without camera access can still send text, but cannot take photos inside the app.
Why does an app ask for permissions again?
If you chose “Ask every time” or the app was paused for being unused, it will ask again the next time it needs access.
Can I see which app used my location recently?
Yes. Many Android versions show recent access in the Privacy section or the Privacy dashboard in Settings.
