How to Change App Permissions on Android: The Complete Guide
When you install an app on your Android smartphone, it frequently asks for access to various features on your device—such as your camera, microphone, precise location, contacts, and photos. While apps like Google Maps legitimately need your location to navigate, a basic flashlight or calculator app requesting access to your contacts or call logs should immediately raise privacy red flags.
Managing app permissions is one of the most effective ways to protect your personal privacy, save battery life, and prevent rogue software from tracking your activity in the background. Modern Android operating systems (Android 10 through Android 15) give you granular control over exactly what each app can and cannot see.
In this comprehensive guide, you will learn how to check, change, and revoke app permissions on any Android device.
Understanding Permission Levels on Android
Before changing settings, it helps to understand how Android categorizes permissions. When an app requests access to a sensitive feature (like your location or microphone), Android usually offers four distinct choices:
- Allow all the time: The app can access the sensor or data even when you are not actively using it (e.g., fitness trackers or navigation apps running in the background).
- Allow only while using the app: The app can access the feature only when the app is actively open on your screen. This is the safest default choice for most applications.
- Ask every time: Every time you open the app and it needs access to that feature, Android will prompt you to approve or deny it on the spot.
- Don't allow / Disallow: The app is completely blocked from accessing that data or hardware feature.
Method 1: Change Permissions for a Single App
If a specific app is acting suspiciously, draining your battery, or repeatedly asking for unnecessary access, you can change its permissions individually in seconds.
Step-by-Step Instructions:
- Open the Settings app on your phone.
- Scroll down and tap Apps (or Apps & notifications / Manage Apps).
- Tap See all apps to view the complete list of installed software.
- Select the specific app whose permissions you want to modify (e.g., Instagram, WhatsApp, or Facebook).
- Tap Permissions.
- You will see two lists: Allowed and Not allowed.
- Tap on any permission (such as Camera, Microphone, or Location) to change its status.
- Choose your desired setting: Allow only while using the app, Ask every time, or Don't allow.
Quick Shortcut: You can long-press any app icon on your home screen or app drawer, tap the App Info icon (a small circle with an "i" inside), and jump directly to step 5.
Method 2: Use the Android Permission Manager (Bulk Audit)
If you want to perform a complete privacy check-up across your entire device, checking apps one-by-one can be tedious. Android's built-in Permission Manager lets you review permissions by category—for example, seeing every single app that currently has access to your camera or contacts list.
Step-by-Step Instructions:
- Open Settings.
- Scroll down and tap Security & Privacy (or Privacy).
- Select Permission Manager (on Samsung Galaxy devices, go to
Settings > Security and privacy > Permission manager). - You will see a list of hardware sensors and data types (Body Sensors, Calendar, Call Logs, Camera, Contacts, Files and media, Location, Microphone, Nearby devices, Phone, SMS).
- Tap on a category—for instance, Microphone.
- Review which apps are set to Allowed all the time, Allowed only while in use, or Not allowed.
- Tap any app in the list to revoke or adjust its permission instantly.
Method 3: Managing Special System Permissions
Some permissions go far beyond simple hardware access; they allow apps to alter how your phone functions. These are known as Special App Access permissions and carry high security risks if granted to untrusted applications.
To access these settings, go to Settings > Apps > Special app access (or search for "Special access" in your settings search bar).
Key Special Permissions to Monitor:
- Display over other apps (Draw overlays): Allows an app to show pop-ups or screens on top of other applications. Malware can misuse this to create fake login screens over your real banking apps to steal passwords.
- Install unknown apps (Sideloading): Allows an app (like a web browser or file manager) to install new
.apksoftware packages onto your device. Keep this Disabled for all apps except trusted web browsers or file managers when explicitly needed. - Notification access: Allows an app to read all incoming notifications, including sensitive two-factor authentication (2FA) verification codes sent via SMS or email.
- All files access: Grants full read/write permission to every photo, document, and download stored on your phone's internal storage.
High-Risk Permissions & Security Checklist
Not all permissions carry equal risk. The table below outlines high-risk Android permissions, why apps request them, and when you should deny them:
| Permission Type | Legitimate Use Cases | Privacy Risk / Potential Misuse | Recommended Setting |
|---|---|---|---|
| Location (Precise) | Maps, rideshare apps, weather widgets, food delivery | Background location tracking, building personal habits/location profiles | Allow only while using app |
| Microphone | Voice recorders, messaging calls, video recording apps | Secret background audio recording or targeted ad tracking | Allow only while using app |
| Camera | Video calling, scanning QR codes, taking photos | Unwanted photo/video captures | Allow only while using app or Ask every time |
| Contacts | Messaging apps, dialers, email clients | Uploading your entire address book to third-party ad servers | Don't allow (unless core app function) |
| SMS & Call Logs | Default phone & messaging apps, SMS autofill | Reading private text messages, intercepting bank OTPs | Don't allow for third-party utility apps |
| Accessibility Services | Screen readers, automated helpers, password managers | Complete control over screen touches and keylogging abilities | Extreme Danger: Grant only to verified safety tools |
Built-In Android Privacy Tools You Should Know
Modern versions of Android include built-in safeguards to help you monitor app behavior automatically:
1. Privacy Dashboard (Android 12 and Newer)
Located under Settings > Security & Privacy > Privacy Dashboard, this feature provides a 24-hour visual timeline showing exactly which apps accessed your Location, Camera, or Microphone, down to the exact minute.
2. Camera and Microphone Privacy Indicators
Whenever an active application accesses your camera or microphone, Android displays a bright green dot in the top-right corner of your status bar. Swiping down reveals which app is currently using the sensor.
3. Quick Settings Privacy Toggles
You can add Camera Access and Mic Access quick setting tiles to your swipe-down menu. Turning these toggles OFF completely cuts power to your camera and microphone hardware-wide, preventing any app from using them until toggled back on.
4. Auto-Reset Unused Permissions
Android automatically revokes permissions from apps you haven't opened in a few months. When enabled (Settings > Apps > [Select App] > Pause app activity if unused), Android revokes all granted permissions to keep inactive apps from running background checks.
Frequently Asked Questions
What happens if I deny a permission an app needs?
If you deny a permission (such as Camera access for a QR reader), the app will simply display a pop-up requesting access again when you try to use that feature. If the feature is optional, the app will continue to function normally for everything else.
Why do some apps crash when I deny permissions?
Older or poorly coded apps may crash if they expect a permission to always be available. If an app crashes, re-open it, grant the permission temporarily, or look for an alternative app on the Google Play Store.
Can free apps sell my location data if I grant location access?
Yes. Many free apps embed third-party advertising SDKs (Software Development Kits) that monetize user data by harvesting location info. To prevent this, set location permissions to "Allow only while using the app" or disable "Use precise location" in permission settings.
Frequently Asked Questions (FAQ)
1. How do I change app permissions on Android?
Open Settings > Apps > Select an App > Permissions. From there, you can allow, deny, or limit access to permissions such as Camera, Microphone, Location, Contacts, and Storage.
2. Which app permissions should I allow?
Only allow permissions that are necessary for the app to function. For example, a camera app needs Camera access, while a navigation app requires Location permission.
3. Can I revoke app permissions at any time?
Yes. Android lets you change or revoke app permissions whenever you want through the Settings menu. The changes take effect immediately.
4. Why are some app permissions automatically removed?
On newer Android versions, permissions for apps you haven't used for a long time may be automatically reset to protect your privacy and improve security.
5. Does changing app permissions improve privacy?
Yes. Managing app permissions helps prevent unnecessary access to your personal information, including your location, photos, contacts, microphone, and camera, making your Android device more secure.
