Managing privacy on your smartphone is no longer a luxury; it is a fundamental necessity in an era where data is the most valuable currency. Understanding how to change app permissions on Android allows you to take full control over your personal information, ensuring that apps only access the data they truly need to function. Whether you are looking to revoke location tracking for a social media app or manage microphone access for a communication tool, navigating the Android Privacy Dashboard and Permission Manager is the key to a secure mobile experience. In this guide, we provide a comprehensive walkthrough of the Android settings ecosystem, helping you audit, adjust, and automate your privacy preferences across all modern versions of the Android OS.
The Critical Importance of Auditing Your Android App Permissions
Every time you install an application from the Google Play Store, it requests access to specific hardware and software components of your device. These are known as app permissions. While many permissions are essential for functionality—such as a navigation app needing GPS location access—others can be invasive. Over-permissioned apps can lead to battery drain, data overages, and, in worst-case scenarios, unauthorized data harvesting.
As mobile security experts, we have observed a significant shift in how Google handles these requests. Since the release of Android 6.0 (Marshmallow), the system transitioned from an “all-or-nothing” install-time model to a runtime permission model. This means you can grant or deny individual permissions at the moment the app actually needs them. However, many users simply click “Allow” without thinking. Periodically reviewing these settings ensures that your digital footprint remains small and your sensitive data—like contacts, call logs, and SMS messages—remains private.
Step-by-Step: How to Change Permissions for a Single App
If you have a specific app in mind that seems to be acting suspiciously or sending too many notifications, the fastest way to restrict it is through the App Info menu. This method is universal across most Android devices, including Samsung Galaxy, Google Pixel, and OnePlus models.
- Open Settings: Swipe down from the top of your screen and tap the gear icon, or find the “Settings” app in your drawer.
- Navigate to Apps: Scroll down and select Apps, Applications, or App Management (the wording varies slightly by manufacturer).
- Select the App: Tap on “See all apps” and find the specific application you want to modify.
- Access Permissions: Inside the App Info screen, tap on Permissions.
- Modify Access: You will see two categories: “Allowed” and “Not Allowed.” Tap on any permission (e.g., Camera, Location, or Contacts) to change its status.
- Choose the Level of Access: For sensitive permissions like Location, you can often choose between “Allow only while using the app,” “Ask every time,” or “Don’t allow.”
Pro Tip: The “Ask Every Time” Feature
For apps that you use infrequently but require sensitive access (like a banking app needing the camera for a check deposit), select “Ask every time.” This ensures the permission is only active for that specific session, preventing the app from accessing the hardware in the background.
Managing Permissions by Category via the Permission Manager
Sometimes, you do not want to look at a specific app, but rather see every app that has access to a specific piece of hardware, such as your Microphone or Calendar. This is where the Permission Manager becomes an invaluable tool for 360-degree privacy coverage.
To access the Permission Manager:
- Go to Settings.
- Tap on Privacy.
- Select Permission Manager.
Here, you will see a list of all available permissions on your phone, including Body Sensors, Call Logs, Files and Media, and Physical Activity. Tapping on “Microphone” will show you exactly which apps have “Always Allowed” access versus “Only While in Use.” This bird's-eye view is the most efficient way to spot rogue applications that have no business accessing your voice or location data.
The Evolution of Privacy: Android 12, 13, and 14 Features
Google has introduced several automated features in recent years to help users who might forget to audit their settings manually. Understanding these features is vital for modern Android security management.
The Privacy Dashboard
Introduced in Android 12, the Privacy Dashboard provides a 24-hour timeline of which apps accessed which permissions. If you see that a wallpaper app accessed your location at 3:00 AM, that is a major red flag. It provides a visual representation of data usage that is much easier to digest than standard menus.
Permission Auto-Reset
If you haven’t used an app for a few months, Android will automatically revoke its permissions and put the app into a “hibernation” state. This prevents “ghost apps” from collecting data in the background. You will receive a notification when this happens, allowing you to re-grant permissions if you decide to use the app again.
Approximate vs. Precise Location
When an app asks for location, you now have the choice between Precise (GPS-level accuracy) and Approximate (Wi-Fi/Cell tower level). A weather app only needs to know your city, not your specific street address. Always opt for “Approximate” unless navigation or fitness tracking is required.
Comparison: Permission Types and Privacy Risk Levels
| Permission Type | Common Use Case | Risk Level | Expert Recommendation | Location | Maps, Weather, Ride-sharing | High | Set to “Only while using app” or “Approximate”. | Camera/Mic | Video calls, Social Media | Critical | Use “Ask every time” for non-essential apps. | Contacts | Messaging, Email | Medium | Deny for games and utility tools. | Files & Media | Photo editors, Storage | High | Use “Photo Picker” in Android 13+ for limited access. | Sensors | Health & Fitness | Low | Allow only for trusted fitness trackers. |

Special Access Permissions: The Hidden Settings
Beyond the standard permissions, there is a layer of “Special Access” settings that control how apps interact with the system at a deeper level. These are often used by system utilities or customization tools, but they can be dangerous if exploited.
To find these, go to Settings > Apps > Special app access. Key settings here include:
- Display over other apps: Allows an app to show a pop-up or overlay. This is how “chat heads” work but can also be used for “clickjacking” attacks.
- Modify system settings: Allows an app to change your ringtone, brightness, or timeout settings.
- All files access: A very powerful permission that lets an app read every file on your internal storage. Grant this only to trusted file managers.
- Usage access: Allows an app to track what other apps you are using and how often.
Expert Perspective: Why “Least Privilege” is the Best Policy
In the world of cybersecurity, we advocate for the Principle of Least Privilege (PoLP). This means an app should only have the minimum permissions necessary to perform its function. If a calculator app asks for your contacts, deny it. If a flashlight app asks for your location, uninstall it. Many of these apps serve as “fleeceware” or data-scrapers designed to build a profile on you for advertisers.

How to Manage Notifications as a Permission
Often overlooked, Notifications are now treated as a permission in newer Android versions (Android 13+). This prevents apps from spamming your notification shade immediately after installation. To manage this:
- Go to Settings > Notifications > App settings.
- Sort by “Most recent” or “Most frequent” to see which apps are cluttering your device.
- Toggle off any app that doesn’t provide time-sensitive, valuable information.
Reducing notifications doesn’t just improve your focus; it also saves battery life by preventing the screen from waking up and the processor from handling background syncs as frequently.
Troubleshooting: What to Do When an App Breaks
Sometimes, revoking a permission can cause an app to crash or malfunction. For example, if you deny “Phone” access to a banking app, it might not be able to verify your identity via SMS or hardware ID. If an app stops working after you change settings:
- Return to the App Info page for that app.
- Re-enable the permission you recently disabled.
- Check if there is a “middle ground” setting (like “Only while using”).
- Ensure you haven’t disabled a Google Play Services permission, as many apps rely on these background services for maps and security.

The Role of the Google Play Store in Permission Security
The Data Safety section in the Google Play Store is a relatively new requirement for developers. Before you even download an app, you can scroll down to see exactly what data the developer claims to collect and whether that data is encrypted or can be deleted. This “nutrition label” for privacy is your first line of defense. If the Play Store listing says the app collects “Personal Info” and “Financial Info” but it is a simple puzzle game, you should look for an alternative.
Advanced Privacy: Using “Work Profiles” for Permission Isolation
For power users, Android’s Work Profile feature (often used in BYOD environments) allows you to create a sandboxed environment on your phone. Apps installed in the Work Profile have their own separate permission set and cannot see the data in your Personal Profile. This is an excellent way to use “necessary evil” apps—those you need for work or specific tasks but don’t fully trust—without giving them access to your personal photos or contacts.
Checklist: Monthly Android Privacy Audit
To maintain a secure device, we recommend performing this 5-minute audit once a month:
- Check for Unused Apps: Uninstall anything you haven’t opened in 30 days.
- Review “Always Allow” Location: Ensure only essential apps (like Find My Device) have 24/7 location access.
- Audit Microphone/Camera: Use the Permission Manager to see if any new apps have gained access.
- Scan with Play Protect: Go to Google Play Store > Profile Icon > Play Protect > Scan to ensure no malicious apps have bypassed security.
- Update Your OS: Ensure you are running the latest Security Patch, as these often include fixes for permission-bypass vulnerabilities.
Frequently Asked Questions
Can I change permissions for system apps?
Yes, but with caution. Some system apps (like the Dialer or System UI) have permissions that are greyed out because disabling them would “brick” the phone’s core functionality. However, apps like Chrome, YouTube, and Google Maps can have their permissions managed just like third-party apps.
Does “Don’t Allow” always stop an app from tracking me?
While it stops the app from accessing official Android APIs for location or data, some sophisticated apps use “fingerprinting” techniques (checking your IP address, battery level, and screen resolution) to estimate your identity. To fully stop tracking, use a VPN and a private browser in addition to strict permission management.
What is “Remove permissions if app is unused”?
This is a toggle found in the App Info > Permissions section. When enabled, Android will automatically strip the app of all permissions if you don’t use it for a few months. It is highly recommended to keep this ON for all non-essential apps.
Why does a simple app need “Nearby Devices” permission?
In Android 12 and later, the “Nearby Devices” permission is used for Bluetooth scanning. If an app needs to connect to a smartwatch, headphones, or a smart home gadget, it needs this permission. Previously, this was lumped into “Location,” so this change actually improves your privacy by separating Bluetooth from GPS.
Summary: Taking Control of Your Digital Sovereignty
Mastering how to change app permissions on Android is the single most effective step you can take to protect your privacy. By moving away from the default “Allow” mindset and adopting a proactive approach via the Permission Manager and Privacy Dashboard, you significantly reduce the risk of data leaks and invasive tracking. Remember that your data belongs to you, and Android provides the tools necessary to keep it that way.
