How to Change App Permissions on Android: The Complete Guide

When you download a new app on your Android phone, it often requests access to your device's core features—including your camera, microphone, precise location, contacts, and photo library. While navigation apps genuinely need location access to function, simple utility apps (like flashlight apps, basic games, or calculators) requesting access to your call history or contacts list pose a serious privacy risk.

Taking control of your app permissions protects your personal data, prevents background battery drain, and stops untrusted software from tracking you. Modern Android operating systems (Android 10 through Android 15) offer granular controls to adjust what each app can access.

Here is a comprehensive guide on how to check, modify, and revoke app permissions on any Android device.

Understanding Permission Levels on Android

Whenever an app requests access to sensitive hardware or data, Android lets you choose between different levels of access:

• Allow all the time: The app can access the feature continuously, even when it is running in the background (e.g., maps, fitness tracking).
• Allow only while using the app: The app can only access the feature when it is active on your screen. This is the safest setting for most applications.
• Ask every time: Every time the app needs access, a prompt appears asking for your approval.
• Don't allow: The app is completely blocked from accessing that data or feature.

Method 1: Change Permissions for an Individual App

If you want to review or change permissions for a specific app that seems to be using too much battery or requesting unnecessary access, you can manage it directly through the settings menu.

Step-by-Step Instructions:

1. Open the Settings app on your phone.
2. Tap Apps (or Apps & notifications / Manage Apps).
3. Select See all apps to list everything installed on your phone.
4. Tap the specific app you want to inspect (e.g., Instagram, WhatsApp, or Facebook).
5. Select Permissions.
6. Review the list under Allowed and Not allowed.
7. Tap any permission (such as Camera, Microphone, or Location) to adjust it.
8. Choose Allow only while using the app, Ask every time, or Don't allow.

Pro Tip: You can also long-press any app icon on your home screen, tap the App Info button (the small circle with an i inside), and select Permissions to jump directly to this screen.

Method 2: Use the Android Permission Manager (Bulk Category Audit)

Checking apps one by one can take a long time. Android’s Permission Manager lets you review permissions by feature category—showing every app that currently has access to your location, camera, or contacts list.

Step-by-Step Instructions:

1. Open Settings.
2. Scroll down and select Security & Privacy (or Privacy).
3. Tap Permission Manager (on Samsung Galaxy devices, go to Settings > Security and privacy > Permission manager).
4. Select a permission category (e.g., Camera, Microphone, or Location).
5. You will see apps sorted into Allowed all the time, Allowed only while in use, and Not allowed.
6. Tap any app in the list to change its access status immediately.

Method 3: Managing Special System Permissions

Certain permissions go beyond standard hardware sensors and grant apps deep system-level control. These fall under Special App Access and should be granted carefully.

To view these, navigate to Settings > Apps > Special app access (or search for "Special access" in the Settings search bar).

Critical Special Permissions to Monitor:

1. Display over other apps (Draw overlays): Allows an app to render screens on top of other running applications. Disreputable software can abuse this to display fake login pop-ups over legitimate banking apps.
2. Install unknown apps (Sideloading): Permits apps (like web browsers or file managers) to download and install new .apk software packages. Keep this disabled for all apps unless actively needed.
3. Notification access: Grants an app permission to read incoming notifications, including sensitive two-factor authentication (2FA) security codes.
4. All files access: Grants full read and write privileges to all documents, downloads, and media files on your internal storage.

High-Risk Permissions Risk Assessment

Not all permissions carry the same security implications. Here is a quick reference guide to high-risk permissions:

Permission	Core Purpose	Potential Privacy Risk	Recommended Setting
Precise Location	GPS navigation, delivery	Tracking physical location history and habits	Allow only while using app
Microphone	Voice calls, audio recording	Background ambient listening or ad profiling	Allow only while using app
Camera	Video calling, scanning QR codes	Unauthorized photo or video recording	Allow only while using app or Ask every time
Contacts	Social networking, messaging	Uploading your full phonebook to third-party ad servers	Don't allow (unless core app feature)
SMS & Call Logs	Default phone & SMS apps	Intercepting bank OTPs and reading personal messages	Don't allow for utility/third-party apps
Accessibility Services	Screen readers, password fillers	Full device control, screen monitoring, keylogging	High Risk: Grant only to verified accessibility tools

Built-In Android Privacy Safeguards

Modern Android versions come with automated tools to help keep permissions in check without manual monitoring:

1. Privacy Indicators (Android 12+): Whenever an active app accesses your camera or microphone, a bright green dot appears in the top-right corner of your status bar. Swiping down reveals which app is using the sensor.
2. Privacy Dashboard: Located at Settings > Security & Privacy > Privacy Dashboard, this feature shows a 24-hour timeline of which apps accessed your Location, Camera, or Microphone.
3. Auto-Reset Unused Permissions: If you haven't opened an app in a few months, Android automatically revokes all granted permissions to keep inactive apps from running background checks.
4. Quick Setting Mute Toggles: You can add Camera Access and Mic Access tiles to your Quick Settings panel. Turning these off disables your camera and microphone hardware system-wide.

Frequently Asked Questions (FAQ)

1. How do I change app permissions on my Android phone?

Go to Settings > Apps > Select the App > Permissions. From there, you can allow, deny, or manage permissions such as Camera, Microphone, Location, Contacts, and Storage.

2. Is it safe to deny app permissions on Android?

Yes. You can deny permissions that are not necessary for an app's functionality. However, some apps may not work properly if essential permissions are turned off.

3. What are the most important app permissions to manage?

The most important permissions include Location, Camera, Microphone, Contacts, SMS, Phone, Storage, Calendar, and Notifications. Grant only the permissions an app genuinely needs.

4. Why does an app keep asking for permission?

An app may request permission repeatedly if it needs access to a feature you've denied or if you've selected the "Ask every time" option for that permission.

5. Can changing app permissions improve privacy and security?

Yes. Managing app permissions helps protect your personal data by preventing unnecessary access to sensitive information such as your location, photos, contacts, microphone, and camera.
