Android permissions control what an app can access or do on your phone. When an APK asks for permission to use the camera, microphone, location, contacts or files, Android is placing a boundary between the app and protected data or actions.
The presence of a sensitive permission does not prove that an APK is malicious. A navigation app may reasonably need location, while a camera app needs camera access. The useful question is whether every requested permission makes sense for the app's stated purpose, source and behaviour.
This guide explains how APK permissions work, which Android permissions deserve extra attention and how to review them before trusting an app.
What are Android app permissions?
Apps run inside an Android security sandbox. Permissions allow an app to cross specific boundaries and use protected information or system features.
Android groups permission behaviour into several broad categories.
Normal permissions
Normal permissions cover lower-risk actions. Android can grant many of them automatically because they present limited risk to the user, other apps and the system.
Runtime or dangerous permissions
Android calls higher-impact access runtime permissions, historically also known as dangerous permissions. They can expose restricted data or allow restricted actions.
Examples include access to:
- precise or approximate location
- camera
- microphone
- contacts
- nearby devices
- phone features
- photos, video or other media
Modern Android normally asks the user to grant these permissions while the app is running. Installing an APK does not mean every requested runtime permission is immediately granted.
Signature permissions
Signature permissions are generally granted only when requesting apps are signed with the same certificate as the app or system component that defined the permission. They are commonly used for trusted communication between apps from the same developer or for system-level relationships.
Special app access
Some powerful capabilities are managed outside the normal runtime-permission dialog. Android may place them under Special app access or another dedicated settings screen.
These capabilities deserve careful review because they can affect broad parts of the device.
High-impact permissions and access to review carefully
Risk depends on context, but the following access should never be approved automatically.
Accessibility access
Accessibility services can observe screen content and interact with apps on the user's behalf. This is essential for legitimate assistive technology, password managers and some automation tools.
It can also be abused to read sensitive information, approve prompts or control the interface. A simple wallpaper, flashlight or casual game normally should not need accessibility access.
Device administrator access
Device-admin capabilities can enforce security rules or make an app harder to remove. They may be appropriate for enterprise device management, anti-theft tools and parental-control software.
Question this request if the developer, company and purpose are unclear.
Install unknown apps
This setting allows a specific app, such as a browser or file manager, to request installation of packages from outside Google Play.
Grant it only to the exact app you use for trusted APK installation. Turn the access off when it is no longer needed. An unrelated app should not need permission to install other apps.
All files access
Broad storage access can expose more files than a normal media or document picker. File managers, backup tools and security utilities may have a valid reason.
A calculator, wallpaper or small offline game usually does not.
Notification access
Notification listeners can read notification content, including message previews and security alerts. Some companion apps and wearable tools use it legitimately.
Treat it as sensitive because notifications may contain personal conversations or one-time information.
Display over other apps
Overlay access lets an app draw above other apps. Chat heads and accessibility tools can use it for visible features, but deceptive overlays may hide or imitate security prompts.
SMS, call logs and phone access
Access to messages and call records can reveal highly sensitive communications. An app should have a clear core function that explains why it needs this information.
Camera and microphone
A camera, video-call or voice-recording app has an obvious need. A utility with no audio or visual feature should not request continuous access.
On supported Android versions, privacy indicators show when the camera or microphone is active. Review recent permission use in the Privacy dashboard when available.
Location
Navigation, weather and delivery apps may need location. Consider whether approximate location is enough and whether access is needed only while using the app.
Background location deserves a stronger justification because it can track movement when the app is not visible.
VPN and network control
A VPN app routes device traffic through a VPN interface. Only approve this for a provider or open-source project you trust and understand.
Permissions must match the app's purpose
Do not judge a permission by its name alone. Judge the relationship between the permission and the promised feature.
Examples:
- A map requesting location is expected.
- A messaging app requesting contacts may be reasonable but should still explain the benefit.
- A flashlight requesting contacts, SMS and accessibility access is a serious warning.
- A file manager requesting storage access may be reasonable.
- A wallpaper app asking to become a device administrator is difficult to justify.
The most concerning pattern is a combination of unrelated, high-impact permissions without a clear explanation.
How to review permissions on Android
Menu names vary by Android version and phone manufacturer, but the usual path is:
1. Open Settings. 2. Tap Apps. 3. Select the app. 4. Tap Permissions. 5. Review allowed and denied permissions. 6. Change access that the app does not need.
You can also review permissions by category through Settings > Security and privacy > Privacy > Permission manager on many current devices.
Special access is usually listed separately. Look for options such as:
- Accessibility
- Device admin apps
- Install unknown apps
- Display over other apps
- Notification access
- All files access
- VPN
Do not approve a special-access request only because an app opens the correct settings page. Read the permission name and decide whether the feature genuinely requires it.
Can you inspect APK permissions before installation?
An APK includes a manifest that declares permissions the app may request. Advanced users and developers can inspect the manifest with trusted Android SDK tools or a reputable offline APK analyser.
Keep these limits in mind:
- a declared runtime permission may never be requested
- an app may request access only when a specific feature is opened
- libraries included in the app can add permission declarations
- permission names do not reveal every way the app processes data
- a manifest review is not a malware analysis
Avoid uploading private, unreleased or company APK files to random online scanners. Uploading a file transfers it to a third party.
Red flags before granting permission
Pause and investigate when:
- the permission has no clear link to the app's purpose
- the app pressures you to enable accessibility or device-admin access
- installation instructions tell you to disable Play Protect
- the app asks for several powerful permissions immediately on first launch
- the developer provides no privacy policy or explanation
- the package imitates a known app but uses a different signer
- the app came from a copied page, shortened URL or unsolicited message
- the app stops working completely when an optional permission is denied
- reviews mention unexpected ads, overlays, battery drain or account activity
A permission request is a decision, not a required step. You can deny it and see whether the core feature still works.
Use Google Play Protect with sideloaded APKs
Google Play Protect checks apps during installation and periodically scans the device. It can warn, disable or remove an app identified as potentially harmful.
For security, Google recommends keeping Play Protect enabled. It may offer to scan an unfamiliar app installed from outside Google Play.
Play Protect is an important layer, but no scanner guarantees that every app is safe. Combine it with source verification, signature checks, permission review and current Android security updates.
How to reduce permission risk
Use the smallest access that lets the feature work.
- Choose approximate location when precise location is unnecessary.
- Choose access only while using the app instead of all the time.
- Select specific photos or files instead of granting broad storage access.
- Deny microphone or camera access until the related feature is used.
- Remove special access after completing a one-time task.
- Uninstall apps that no longer have a clear purpose.
Android can automatically reset runtime permissions for apps that have not been used for a period of time on supported versions. This reduces long-term access but does not replace your own review.
What happens if you revoke a permission?
The app loses the protected access controlled by that permission. A related feature may stop working, but unrelated features should continue when the app is designed correctly.
If an app crashes after access is denied, check for an update. Developers are expected to handle permission denial gracefully.
Revoking a permission does not erase information the app may already have collected or uploaded. Review the developer's privacy policy and delete the account or stored data separately when necessary.
APK permission safety checklist
Before trusting an APK:
- download from a source you can verify
- check the package name and developer
- verify the APK signature
- keep Play Protect enabled
- compare requested access with the app's actual purpose
- deny unrelated runtime permissions
- review Special app access separately
- prefer one-time or while-in-use access
- check the Privacy dashboard after using the app
- remove permissions or uninstall the app if behaviour changes unexpectedly

This guide was reviewed in August 2026 using official Android Developers documentation for Android permissions, runtime permission requests and permission minimisation, together with Google Play Help documentation for changing app permissions and Google Play Protect.
Permissions should be reviewed as part of a broader safety check. A short permission list is not proof of safety, and a sensitive permission is not proof of malware. Context, source, signer identity and app behaviour all matter.
