Checking and Managing App Permissions on Android

Introduction / Why This Matters

Every app on your Android device requests specific permissions to access phone functions: camera, microphone, contacts, location, etc. Often, apps ask for more access than they truly need, creating risks to your privacy and security.

Regularly reviewing and adjusting these permissions is a key practice of digital hygiene. You not only limit unnecessary data collection but may also improve your device's battery life, as apps will run less in the background.

After completing this guide, you'll be able to independently control which app accesses your data and hardware components and when.

Requirements / Preparation

Before you begin, ensure:

1. You have a device running Android 8.0 (Oreo) or newer. The interface and menu names may vary slightly depending on the manufacturer (Samsung One UI, Xiaomi MIUI, Pixel Android) and OS version, but the general logic remains the same.
2. You have physical access to the device (not remote management).
3. The device is unlocked (not strictly necessary, but more convenient).

Step-by-Step Guide

Step 1: Open System Settings

On your phone's home screen, find the "Settings" icon (usually a gear). You can also access it by swiping down the notification shade and tapping the gear icon.

💡 Tip: On some devices (e.g., Xiaomi), the apps section may be called "Apps" or "App management" and located inside "Settings".

Step 2: Go to the "Apps" Section

In the opened settings menu, scroll down and find the "Apps" item. Tap it. You will see a complete list of all programs installed on the device.

Step 3: Select the Desired App

In the app list, find the program whose permissions you want to check. If the list is long, use the magnifying glass icon (search) at the top of the screen and enter the app's name (e.g., "Instagram", "Telegram").

Tap the app's name to go to its details page.

Step 4: Open the "Permissions" Menu

On the app info page (usually featuring buttons like "Force stop", "Clear cache", "Uninstall"), find and select the "Permissions" item.

A new screen will open showing a list of all access categories the app requests: "Camera", "Microphone", "Contacts", "Precise location", "Files and media", and others.

Step 5: Analyze and Change Access

Carefully review the list. Next to each permission, its current status is indicated: "Allowed", "Denied", or "Allowed only while using the app".

1. Tap any permission to see detailed information on why the app needs it and to change its status.
2. For enhanced privacy, it is recommended for sensitive permissions (camera, microphone, location, contacts) to select the option "Only while using the app". This prevents background access.
3. If a permission seems unnecessary for the app's core function (e.g., SMS access for a file manager), feel free to change it to "Deny".
4. After making a change, press "Done" or back to save the setting.

⚠️ Important: If you deny a critical permission (e.g., phone access for a messenger), the app may stop working or a specific feature may become unavailable. The system usually shows a warning about this the first time the feature is accessed.

Verifying the Result

1. Return to the home screen and try using the app whose permissions you changed.
2. Attempt to use a function that requires the modified permission (e.g., take a photo within a messenger). Ensure everything works normally or, if you denied access, that the app correctly reported an error and offered to enable the permission in settings.
3. For full confidence, you can also check the system settings under "Privacy" (or "Security & privacy"), where there is often a summary report of app activity over the last 24 hours.

Potential Issues

• The "Permissions" section is unavailable or grayed out. This may mean the app is a system app (pre-installed) or a device administrator. Its permissions cannot be changed using standard tools without root privileges or special utilities.
• The app stopped working after disabling a permission. Some developers intentionally break functionality if they don't receive all requested permissions. Solution: either restore the permission or find an alternative app with a more reasonable privacy policy.
• Different menu names. On firmware from Samsung, Xiaomi, Oppo, and other manufacturers, the paths may differ. If you don't see "Apps", look for "App management", "Apps & notifications", or "Privacy". Inside these sections, you will always find the app list.
• The "Modify system settings" permission. This is a special, powerful permission that gives an app near-complete control over the device. It does not appear in the standard app permissions list. You can check which apps have it in the settings under "Special permissions" or "Access to special features" (the path may vary). Revoke it only if you are absolutely certain about the app's necessity.
