Many Android apps ask for access to your location, camera, microphone, contacts, or photos. Some permissions are necessary for an app to work, but others may no longer be needed after installation. Reviewing these settings helps you decide what information each app can access.

You do not need to install a separate privacy app to get started. Android includes built-in tools for checking app permissions, reviewing recent access, and revoking access you no longer want to allow.

1. Open the App Permissions Settings

The easiest way to review permissions is to start with an individual app. This lets you see exactly what that app can access and change permissions without affecting every other app on your phone.

1. Open the Settings app on your Android phone.
2. Tap Apps.
3. Select the app you want to review. If it is not visible, tap See all apps.
4. Open Permissions.
5. Review the permissions marked as allowed or denied.
6. Tap a permission and choose the appropriate access option.

For example, a calculator app may not need access to your contacts or microphone. A video-calling app, on the other hand, needs microphone and camera access for calls to work.

The exact menu names can vary by Android version and phone manufacturer. Google’s official guide to changing app permissions explains the standard process.

2. Check Permissions by Category

Checking every app individually can take time. Android’s Permission Manager lets you see which apps have access to a particular type of information or device feature.

1. Open Settings.
2. Look for Security & privacy or Privacy.
3. Open Permission manager, if available.
4. Select a permission, such as Location, Camera, Microphone, or Contacts.
5. Review the apps listed and change access for any app that does not need it.

This approach is useful when you want to find every app that can access your location or microphone instead of searching through your installed apps one at a time.

Some manufacturers use different menu names or locations. If you cannot find Permission Manager, search for “Permissions” in Settings or open the permissions page for an individual app.

3. Which App Permissions Should You Review?

Some permissions deserve more attention because they provide access to personal information or sensitive device features.

• Location: Check which apps can access your location all the time. For apps that only need your location while you use them, consider limiting access to that period.
• Camera and microphone: Review whether each app needs to take pictures, record video, or capture audio.
• Contacts: Decide whether an app genuinely needs access to your address book.
• Photos and videos: Check whether an app needs access to your entire media library or can work with only the files you select.
• SMS and call logs: Review these carefully because they can expose communications and account verification messages.
• Nearby devices: Check whether the permission makes sense for apps that connect to Bluetooth accessories or other nearby hardware.

Do not assume that an app is suspicious simply because it requests a permission. A navigation app needs location access, while a photo-editing app may need access to selected images. The important question is whether the requested access makes sense for the app’s purpose.

4. Choose the Right Permission Option

Android may offer several access options depending on the permission and operating system version.

• Allow all the time: Available for certain permissions, such as location, when an app needs access in the background.
• Allow only while using the app: The app can use the permission while you are actively using it.
• Ask every time: Android asks for permission again when the app requests access, where supported.
• Don’t allow: The app cannot use that permission.

For location access, Android may also let you choose approximate rather than precise location. This can be useful for apps that only need to know your general area.

Choose the least access that still lets the app do what you need. However, denying a necessary permission may disable a feature. If an app stops working after you revoke access, return to its settings and allow the permission when required.

5. Use the Privacy Dashboard to Check Recent Access

On supported Android versions, the Privacy Dashboard shows which apps accessed certain permissions and when that access occurred. This is especially useful if you want to investigate unexpected camera, microphone, or location activity.

1. Open Settings and find Privacy Dashboard.
2. Select the permission you want to investigate.
3. Review the apps that accessed it and the available activity history.
4. Tap an app to manage its permission if you want to change access.

Availability and the amount of history shown depend on the Android version. Google’s documentation describes the dashboard’s history for different versions, so the time range may not be identical on every device.

See Google’s Privacy Dashboard guide for details.

6. Check When Your Camera or Microphone Is Active

On Android 12 and later, a green indicator appears near the top of the screen when an app uses the camera or microphone. On supported devices, you can tap the indicator to see which app or service is using that sensor.

You can also swipe down to open Quick Settings and use the camera or microphone access controls if your device provides them. These controls can temporarily disable access across apps.

A green indicator is not automatically a sign of spying. Video calls, voice messages, camera apps, and other legitimate features may activate these sensors. If the activity looks unexpected, check which app is responsible and review its permissions.

Google explains these indicators and controls in its camera and microphone privacy guide.

7. Automatically Remove Permissions From Unused Apps

Android can automatically reset permissions for certain apps you have not used for a while. This reduces the chance that an abandoned app keeps access to sensitive information indefinitely.

To check whether the feature is enabled:

1. Open Settings → Apps.
2. Select an app you rarely use.
3. Look for Pause app activity if unused or the equivalent unused-app setting.
4. Enable the option if it is available and suitable for that app.

The exact wording can vary. Review the setting before enabling it, particularly for apps you need to receive alerts or perform background tasks.

Final Thoughts

Reviewing Android app permissions is a simple way to improve privacy without installing extra software. Start with location, camera, microphone, contacts, and photos, then use Permission Manager and Privacy Dashboard to investigate access more efficiently.

You do not need to deny every permission. Instead, give each app only the access it needs, revisit permissions occasionally, and investigate unexpected activity. This gives you more control over your personal information while keeping the apps you rely on working properly.
