Complete Guide to Managing App Permissions on Android

Introduction / Why This Matters

Android app permissions are a mechanism that controls program access to your device's functions and data: camera, microphone, contacts, location, and other resources. Managing these permissions is critical for protecting privacy, saving battery life, and preventing unwanted background activity. This guide will help you master checking and configuring access rights so you feel secure and in control of how apps use your data.

Requirements / Preparation

Before you begin, ensure that:

• Your device is running Android 6.0 (Marshmallow) or newer, as the dynamic permissions system was introduced with this version.
• You have access to your device's system settings.
• The app for which you want to change permissions is already installed.

Step-by-Step Instructions

Step 1: Open Your Device Settings

On the home screen or in the app drawer, find the "Settings" icon (usually represented by a gear). Tap it to open the main system settings window.

Step 2: Navigate to the "Apps" Section

In Settings, scroll down the list and find the "Apps" or "Apps & notifications" entry (the name may vary slightly depending on the manufacturer and Android version). Tap this item to see the full list of installed applications.

💡 Tip: On devices with Android 11 and higher, you can also quickly open an app's info by long-pressing its icon on the home screen and selecting "App info" from the menu that appears.

Step 3: Select the Desired App

In the list that opens, find the app whose permissions you want to change. Tap its name or icon. A page with detailed information about the app will open, showing its version, storage usage, and other parameters.

Step 4: Open the "Permissions" Section

On the app's page, find and select the "Permissions," "App permissions," or "Permissions" entry. Depending on the Android version and the manufacturer's skin (e.g., Samsung One UI, Xiaomi MIUI), the name may vary: "Access to functions," "App permissions," etc.

Step 5: Review and Modify Current Permissions

You will arrive at a screen listing all permissions requested by the app. Each permission has a status: "Allowed" (access granted) or "Denied" (access blocked). To change a status:

1. Tap the desired permission (e.g., "Camera," "Microphone," "Contacts").
2. In the dialog that appears, choose one of the options:
   • Allow — the app can use the function.
   • Deny — access is completely blocked.
   • Only while using the app (available for some permissions, like location) — access is granted only when the app is active on screen.
3. Confirm your selection if prompted.

⚠️ Important: If you deny a permission that is critical for the app's core functionality (e.g., "Camera" for a photo editor), the app's functionality may be impaired or it may fail to launch. In this case, revert the permission to "Allowed."

Step 6: Reset Permissions to Default (Optional)

If you want to undo all manual changes and restore permissions to their original state (as on first app launch):

1. In the "Permissions" section, press the menu button (three dots in the top-right corner).
2. Select "Reset app permissions" or "Restore default permissions."
3. Confirm the action. All permissions will return to the state defined by the developer.

Step 7: Test the App

After making changes, open the app and test its key functions. For example, if you disabled microphone access, try recording an audio message—you should see a notification about missing permission. If something works incorrectly, return to Settings and adjust the permissions accordingly.

Verifying the Result

To ensure your changes took effect:

• Return to the "Permissions" section for the selected app and check that the statuses match your settings.
• Confirm that the app no longer requests denied permissions on startup (e.g., system dialogs asking for contacts access do not appear).
• Test all usage scenarios important to you to confirm the app runs stably with the new settings.

Potential Issues

• App stopped working after disabling a permission: This means the disabled permission is critical. Re-enable it by setting it to "Allowed," or if the app requests excessive access, consider finding an alternative app with a more conservative permissions policy.
• "Permissions" item is missing in the app's settings: On very old Android versions (pre-6.0), the permissions system is not supported—all rights are requested at install time and cannot be changed. In this case, update your operating system or use third-party tools (like ADB), but this requires additional knowledge.
• System permissions cannot be disabled: Some permissions related to system functions (e.g., "Display over other apps," "Modify system settings") are managed in other sections. Look for them under "Special permissions" or "Access to special features" in the main Settings.
• Permissions automatically reset after an app update: Some apps may reset user permission preferences after an update. After each update, check the permissions section to ensure your settings are preserved.
• Different behavior on different Android skins: Manufacturers (Samsung, Xiaomi, Huawei, etc.) often add their own permission managers or duplicate settings. If you cannot find the standard path, look for "Permissions" or "Access" sections within the app's settings—they may be prominently placed.
