| Learn how to review and change Android app permissions to protect your privacy, limit unnecessary access, and improve device security. |
To change app permissions on Android, go to Settings → Apps → [select app] → Permissions, then tap any permission to switch it between Allow, Allow only while using the app, Ask every time, or Don't allow. For a full privacy audit across every app at once, use Settings → Security & Privacy → Permission Manager instead. Below is the complete breakdown, including the permissions worth the most scrutiny and the newer Android tools most people don't know exist.
Why Your App Permissions Deserve a Second Look
Download a simple flashlight or calculator app and it may still ask for your Contacts, Location, or Microphone — access it has no real need for. Since Android 12, Google has steadily expanded user control over this: you can grant "Approximate" location instead of "Precise," limit access to "Only this time," and review exactly which apps touched your camera or mic in the last 24 hours. These tools only help if you actually use them.
A quick audit matters for four practical reasons:
- - Privacy: Apps with unnecessary microphone or contacts access can collect more about you than they need to function.
- - Battery life: Apps with "Allow all the time" location access repeatedly ping GPS in the background, draining your battery.
- - Security: Malicious apps sometimes request SMS access specifically to intercept banking OTPs — denying this permission breaks that attack path.
- - Performance: Fewer background permissions means fewer processes competing for system resources.
Method 1: Change Permissions for One Specific App
Use this when you've just installed an app, or one is behaving suspiciously.
1. Long-press the app's icon until a menu appears.
2. Tap App Info (the "i" in a circle).
3. Tap Permissions.
4. You'll see two lists: Allowed and Not Allowed.
5. Tap any permission (e.g., Camera) to change it:
- - Allow all the time
- - Allow only while using the app
- - Ask every time
- - Don't allow
Practical tip: Denying a permission rarely breaks an app permanently — most apps simply ask again the next time they need it (e.g., Instagram will re-prompt for Camera access when you try to take a photo). This makes it low-risk to be strict.
Method 2: Audit by Permission Type (Permission Manager)
This is the better approach if you want to answer a specific question: which apps can currently see my location, or hear through my microphone?
1. Open Settings.
2. Tap Security & Privacy (labeled just "Privacy" on some devices).
3. Tap Permission Manager.
4. Choose a category: Location, Camera, Microphone, SMS, Contacts, Call Logs, Body Sensors, Calendar.
5. Review the Allowed list for that category and revoke anything that doesn't need it — this is how you catch apps you installed months ago and forgot about.
The Three Permissions Worth Extra Caution
1. Location: Precise vs. Approximate
Since Android 12, you can choose between:
- - Precise — pins your exact location. Reasonable for navigation apps like Google Maps or ride-hailing apps that need to find you.
- - Approximate — narrows location to within a few kilometers. Sufficient for weather or news apps that only need your general area.
How to set it: Tap the Location permission for an app and toggle "Use precise location" off if the app doesn't need exact positioning.
2. Microphone and Camera
Android displays a small green indicator dot in the status bar whenever an app is actively using your camera or microphone — a privacy feature Google introduced with Android 12 and refined in later versions.
Audit tip: If you see that dot while just reading a PDF or playing a offline game, open Permission Manager immediately and revoke access for whichever app triggered it.
3. Photos and Files (Scoped Storage)
Older Android versions granted "Allow access to all photos" as an all-or-nothing choice. Modern Android's Photo Picker lets you select "Select Photos" instead, giving an app access only to the specific images you choose — not your entire gallery. Choose this option whenever it's offered.
Special App Access: The Hidden Permissions Worth Checking
Beyond standard camera/mic controls, a few system-level permissions are worth reviewing periodically. Find them under **Settings → Apps → Special App Access** (sometimes under a three-dot menu).
| Permission | Risk if Misused | What to Do |
|---|---|---|
| Display over other apps | Can create fake login overlays to steal passwords | Only grant to apps you fully trust |
| Install unknown apps | Lets an app install other APKs without your review | Keep off except temporarily on your file manager/browser |
| Device Admin Apps | Full remote wipe/lock control | Ensure only your official "Find My Device" has this |
| Notification Access | Can read incoming notifications, including OTPs | Grant sparingly |
Two Tools Most Users Overlook
Permission Auto-Reset: If you haven't opened an app in months, Android automatically revokes its permissions. Check the toggle labeled "Pause app activity if unused" on any app's permission page and make sure it's on for apps you rarely open (travel or seasonal apps, for example).
Privacy Dashboard: Found under Settings → Security & Privacy → Privacy Dashboard, this shows a 24-hour timeline of exactly when each app accessed your camera, microphone, or location — useful if you suspect an app is accessing a sensor more than it should.
Troubleshooting: When Restricting a Permission Breaks an App
If you deny an app a permission it genuinely needs (e.g., Files access for WhatsApp), the fix is straightforward:
1. Try the action again (e.g., tap the attachment icon in WhatsApp).
2. The app will prompt you to grant the specific permission.
3. Tap Allow on that prompt, or go manually to Settings → Apps → [App] → Permissions and enable it.
One rule worth following: never grant a permission just to silence an error message without reading what's being requested. If a flashlight app insists on Contacts access to function, that's a sign to delete it rather than comply.
Frequently Asked Questions
Can I change permissions for system apps like Google Play Services?
Generally no — core system apps have permissions hard-coded into Android's function, and revoking them can cause crashes.
What is the "Nearby Devices" permission?
It lets an app detect Bluetooth devices like headphones or smartwatches without needing your GPS location — introduced as a privacy improvement in Android 12.
Why does an app ask for a permission again after an update?
Updates sometimes reset permissions or add features requiring new access. Review the request rather than tapping Allow automatically.
How do I stop ad tracking on Android?
Go to Settings → Security & Privacy → Ads, where you can reset or delete your advertising ID.
Conclusion
Changing app permissions on Android takes a few minutes but gives you real, ongoing control over what your apps can see and hear. Start with the Permission Manager, check your Location and Microphone tabs first, and revoke anything that doesn't have a clear reason for access.
Note: Menu names and steps can vary slightly by manufacturer (Samsung One UI, Xiaomi HyperOS, Tecno HiOS). The steps above reflect the stock Android layout used across most 2026 devices.
