The “Draw over other apps” permission, also known as “Display over other apps” or “Appear on top,” is a special Android permission that allows an application to display content on top of other running applications or the device’s home screen. While this functionality can enhance user experience by enabling features like chat bubbles, screen filters, or floating widgets, it can also pose security risks and lead to performance issues if misused. This article provides a detailed explanation of this permission, its implications, and how to manage it effectively on your Android device.
Understanding and managing the “Draw over other apps” permission is crucial for maintaining device security and optimizing performance. Many legitimate applications utilize this feature for convenient overlays, but it’s equally important to be aware of how malicious apps can exploit it. This guide will walk you through identifying apps with this permission, disabling it when necessary, and recognizing scenarios where it might be causing issues.
Understanding the “Draw Over Other Apps” Permission
The “Draw over other apps” permission grants an application the ability to create overlays on your screen, meaning it can display its own content on top of any other app or the system UI. This is a powerful permission, distinct from standard runtime permissions, as it allows an app to operate visually even when it’s not in the foreground.
Common examples of apps that legitimately use this permission include:
- Messaging apps: For chat heads or floating notifications (e.g., Facebook Messenger).
- Screen dimming apps: To apply a filter over the entire screen for eye comfort.
- Screen recorders: To display control buttons or indicators while recording.
- Accessibility services: To provide visual aids or interactive overlays for users with disabilities.
- System tools: Such as battery monitors or quick settings toggles that appear on top.
While beneficial, this permission carries inherent risks. Malicious applications could potentially use it to:
- Overlay deceptive content: Tricking users into entering sensitive information into fake login screens or unknowingly tapping on hidden elements.
- Display intrusive ads: Interrupting user experience with persistent, hard-to-dismiss pop-ups.
- Degrade performance: Excessive or poorly optimized overlays can consume significant battery life and slow down your device.
Identifying and Managing Apps with “Draw Over Other Apps” Permission
Android provides a dedicated setting within your device’s system settings to manage applications that have or can request the “Draw over other apps” permission. The exact navigation may vary slightly depending on your Android version and device manufacturer (e.g., Samsung, Xiaomi, OnePlus).
To access and manage this permission:
- Open Settings: Locate and tap on the “Settings” icon on your Android device.
- Navigate to Apps: Look for a section like “Apps,” “Applications,” or “Apps & notifications.”
- Find Special Access: Within the “Apps” menu, search for “Special app access” or “Advanced” settings.
- Locate “Display over other apps”: Tap on the option labeled “Display over other apps,” “Draw over other apps,” or “Apps that can appear on top.”
- Review and Modify: You will see a list of all applications that have requested or currently possess this permission. For each app, you can toggle the permission “On” or “Off.”
Table: Typical Navigation Path (may vary)
| Android Version | Common Path |
| Android 10+ | Settings > Apps > Special app access > Apps that can appear on top |
| Android 7-9 | Settings > Apps > (Gear icon or three dots for Advanced) > Special access > Draw over other apps |
| Older Versions | Settings > Apps > Draw over other apps |

It is recommended to only grant this permission to applications you trust and actively use for features that genuinely require screen overlays. If you suspect an app is misbehaving or causing issues, disabling this permission for that specific app is a good first troubleshooting step.
Troubleshooting “Screen Overlay Detected” Errors
A common scenario where the “Draw over other apps” permission becomes problematic is when you encounter a “Screen overlay detected” error. This error typically occurs when a foreground app tries to request a sensitive permission (like accessing contacts or storage), but another app with “Draw over other apps” permission is actively displaying an overlay. Android’s security mechanism flags this as a potential “tapjacking” risk, where a malicious overlay could trick you into granting permissions to an unintended app.
To resolve a “Screen overlay detected” error:
- Identify the culprit (if possible): Sometimes the error message itself might hint at the app causing the conflict. If not, you’ll need to systematically check recently installed or frequently used apps that utilize overlays.
- Disable “Draw over other apps” temporarily: Go to the “Display over other apps” settings as described in the previous section. Temporarily disable the permission for any suspicious or recently installed apps. You might need to disable several to identify the problematic one.
- Retry the action: Once the overlaying apps are disabled, try to perform the action that triggered the “Screen overlay detected” error (e.g., granting the permission to the legitimate app).
- Re-enable permissions selectively: After completing the sensitive action, you can re-enable the “Draw over other apps” permission for your trusted applications one by one, verifying that the error does not reappear. This helps you pinpoint the specific app causing the conflict.
Pro-Tip: If the error persists or you cannot identify the problematic app, restarting your device in Safe Mode can temporarily disable all third-party apps, allowing you to perform the sensitive action without interference. After completing the action, you can restart your device normally.
Security Implications and Best Practices
The “Draw over other apps” permission, while functional, requires careful consideration due to its security implications. An app with this permission can potentially obscure legitimate UI elements, leading to unintended taps or data exposure.
Best practices for managing this permission include:
- Be selective with grants: Only enable “Draw over other apps” for applications from reputable developers that genuinely need this functionality.
- Review permissions regularly: Periodically check the list of apps with this permission in your device settings and revoke access for any apps you no longer use or trust.
- Download apps from trusted sources: Stick to the Google Play Store or other official app stores to minimize the risk of installing malicious applications.
- Stay updated: Keep your Android operating system and all your applications updated to receive the latest security patches and bug fixes.
- Be aware of context: If you’re prompted to grant a permission and simultaneously see an unexpected overlay, proceed with caution and investigate the source of the overlay.
By understanding the “Draw over other apps” permission and following these best practices, you can effectively manage your Android device’s security and optimize its performance. Taking control of this powerful permission ensures that your device remains secure and responsive while still allowing you to benefit from the convenience of legitimate overlay features.
