Why App Permissions Matter
Every app on your Android device can only access what you allow it to. Permissions are the system Android uses to ensure apps can't silently access your camera, microphone, location, contacts, or files without your knowledge. Reviewing and managing these permissions regularly is one of the most effective ways to protect your privacy.
This tutorial walks you through finding, reviewing, and adjusting app permissions on Android — and explains what each permission actually means.
How to View Permissions for a Specific App
- Open Settings on your device.
- Tap Apps (or Application Manager).
- Select the app you want to review.
- Tap Permissions.
- You'll see a list of all permissions the app has requested, divided into Allowed and Not allowed sections.
From here, you can tap any permission to change it — allowing, denying, or (for location and certain other permissions) setting it to "Only while using the app".
How to View All Apps Using a Specific Permission
Want to see every app that has access to your microphone? Android makes this easy:
- Go to Settings → Privacy → Permission Manager.
- Tap any permission category (e.g., Microphone, Camera, Location).
- You'll see three groups: Allowed all the time, Allowed only while in use, and Not allowed.
- Tap any app in the list to adjust its permission directly.
Understanding the Key Permissions
| Permission | What It Accesses | Risk if Misused |
|---|---|---|
| Location | GPS and network location | Tracking your movements |
| Camera | Front and rear cameras | Photo/video capture without consent |
| Microphone | Device microphone | Audio recording in the background |
| Contacts | Your address book | Harvesting personal data |
| Storage | Files and photos | Accessing or exfiltrating personal files |
| SMS | Read/send text messages | OTP interception, premium SMS fraud |
| Phone | Call logs, make calls | Toll fraud, call log harvesting |
Best Practices for Managing Permissions
Use "Only While Using the App" for Location
Almost no app genuinely needs your location in the background. Setting location to "Only while using the app" prevents passive tracking when you're not actively using it.
Deny Permissions You Can't Explain
If an app requests a permission that has no obvious connection to its function, deny it. Many apps work perfectly fine with reduced permissions — they just prefer broader access.
Review Permissions After Updates
App updates can introduce new permission requests. Check permissions after a significant app update, especially if the app's behaviour seems to have changed.
Use the Privacy Dashboard
Android 12 and later includes a Privacy Dashboard (Settings → Privacy → Privacy Dashboard) that shows a timeline of which apps accessed sensitive permissions over the past 24 hours. It's an excellent tool for spotting unexpected access.
What Happens When You Deny a Permission?
Denying a permission simply means that feature of the app won't work. For example, denying location access to a maps app means it can't show your current position — but it can still function for manual address searches. Most apps handle denied permissions gracefully. If an app refuses to work at all when you deny a non-essential permission, that itself is a red flag worth noting.
Summary
Taking five minutes to audit your app permissions can meaningfully improve your privacy. Start with the Permission Manager, focus on camera, microphone, and location, and apply the principle of least privilege — give apps only what they need to do their job, nothing more.
