Users of Android devices often encounter a situation where a specific application stops working correctly or refuses to start at all due to the lack of special permission. Android security requires explicit confirmation from the user before the software can interact with the interface on top of other windows. However, sometimes the activation button becomes inactive, gray or disappears altogether, which raises a logical question about how to fix this problem and regain control of the device.
The reason for this behavior of the system may lie in various factors: from conflicts with installed launchers to specific restrictions imposed by the smartphone manufacturer for security purposes. In some cases, blocking is a normal reaction of the operating system to the detection of potentially malicious code, and in others it is a consequence of a software failure after a firmware update. Understanding the nature of blocking is the first step to successfully restoring functionality.
In this article we will analyze in detail the algorithms of actions for various scenarios when the standard path for enabling rights is blocked. We will consider both software solutions through the developer settings, as well as more complex options using USB debugging.
Diagnostics of the reasons for blocking a function
Before taking active steps to unlock, you need to understand why the Android system has prohibited changing the permission status. Most often, the problem lies in the fact that the currently active application is already using the window overlay function. The operating system blocks access to the settings menu to prevent screen control conflicts when one application tries to override the settings of another.
Often the culprits are so-called “blue light filters,” voice recorders with call recording capabilities, or memory cleaning applications that run in the background. If you have installed Clean Master, DU Battery Saver or any third-party launcher other than the standard one, try disabling them temporarily. This will allow the system to unlock access to the menu Special Features.
Another common reason is the application's power saving mode or "Sleep" mode. If the system enforces restrictions on a app's background activity, it may automatically revoke the right to display on top of other windows. Check the battery settings for your specific app and make sure it is set to Unlimited. Only after eliminating these factors can you proceed to technical solution methods.
⚠️ Attention: If the settings menu is covered by some window, you will not be able to click on the desired item. In this case, restart the device in Safe Modeto disable all third-party applications and gain access to the system.
Standard activation path through settings
In most cases, when a function is not blocked by system restrictions, it can be enabled through the standard menu. The path may differ slightly depending on the version of Android and the manufacturer's shell (MIUI, OneUI, ColorOS), but the logic remains the same. You need to find the section responsible for special permissions that are not included in the group of standard access rights.
Go to the main device settings and find the section Applications or Applications and notifications. Inside this menu, look for the subsection Special access or Advanced settings. This is where critical permissions are hidden, such as accessing data usage in the background, changing system settings and, of course, displaying on top of other applications.
After entering the menu On top of other applications you will see a list of all installed apps. Find the application you need in the list and switch the toggle switch to the active position. If the list is empty or the app is not listed, it may not have requested this permission yet when first launched. In this case, try launching the application itself and performing an action that requires this right.
- 📱 For pure Android, the path is usually this: Settings → Applications → Special. access → On top of other applications.
- ⚙️ On Xiaomi devices (MIUI): Settings → Passwords and security → Privacy → Special. access → Display on top of other applications.
- 🛡️ On Samsung (OneUI): Settings → Applications → Three dots in the corner → Special. access → On top of other applications.
If you cannot find an item in the menu, use the search in the smartphone settings by entering the phrase “on top” or “overlay”. This is the fastest way to get to the desired menu.
Solving the problem through developer options
If the standard interface does not allow you to change settings, and the button remains inactive, you should turn to the advanced system tools. Developer mode gives you access to deep Android settings that can help you bypass software locks. However, this method should be used with caution, since incorrectly changing parameters can affect the stability of the interface.
First, you need to activate developer mode. Go to the About phone section in the settings and find the item Build number. Click on it quickly 7 times in a row until a notification appears indicating that you have become a developer. After this, a new section will appear in the main settings menu For developers, usually located at the very bottom of the list or in the "System" section.
Inside the developer menu, find the item related to simulating additional displays or window management. In some versions of Android, there is an option Force to allow background activitythat may indirectly affect the operation of overlays. A more effective method is to clear the Settings service data through the app menu, but this will reset all your user preferences on the system.
| Option in the developer menu | Impact on overlays | Recommended value |
|---|---|---|
| Do not turn off the screen | Prevents dimming, can help with diagnostics | Off (default) |
| Window animation | Visual effect, does not affect rights | 1x or Off |
| Simulation additional. displays | May conflict with overlays | No |
| Show touches | Diagnostic tool | Off |
⚠️ Attention: Changing the settings in the "For Developers" section may lead to unstable operation of the smartphone. Do not change the parameter values if you are not sure of their purpose.
Using ADB to force it on
The most powerful tool that allows you to bypass any graphical limitations of the interface is USB debugging via a computer. The interface Android Debug Bridge (ADB) allows you to send commands directly to the system, bypassing the standard settings menu. This method requires a computer, a USB cable, and the driver installed for your device.
First enable USB debugging in the developer menu mentioned above. Connect your smartphone to your computer and open a command prompt or terminal in the folder with installed platform tools. You will need to know the exact package name of the application for which you want to enable the permission. This can be done through the command adb shell pm list packages or using third-party applets on the phone itself.
To grant overlay rights, use the command appops. The command syntax is as follows:
adb shell appops set SYSTEM_ALERT_WINDOW allowReplace with the real name, for example com.facebook.katana for Facebook or com.telegram.messenger for Telegram. After entering the command and pressing Enter, the system will instantly grant permission, even if the button in the settings was blocked. This is one of the most reliable ways to solve the problem when the software interface is not responding.
Where to download ADB?
Platform-Tools are available for free on the official Android developers website. You don’t need to install an entire development studio, just download the archive with the ADB and Fastboot utilities.
Specifics of the MIUI, EMUI and Flyme shells
Chinese smartphone manufacturers often implement their own aggressive memory and security management systems that can block Android system functions. Owners of devices Xiaomi, Huawei and Meizu face the problem of unavailability of the function more often than others. In these shells, the right to overlay windows is closely related to autorun and work in the background.
On devices with the MIUI shell, it is critical to log into the application Security (green icon with lightning). Inside, find the "Permissions" section and then "Display on top of other applications." If an app is blocked here, Android system settings will not allow it to be enabled. Also check the "Autorun" section - without it, the overlay function may not work correctly.
In the EMUI and MagicOS shells from Huawei, the situation is complicated by the presence of the "Do not disturb" mode and strict battery optimization. You need to add the application to the power saving mode exceptions. Sometimes it helps to completely reset the application settings through the menu Applications → Manage applications, after which the rights are reset and requested again the next time you start it.
- 🔋 Xiaomi: Check the settings in the "Security" application, and not just in the general system settings.
- 🚫 Huawei: Disable battery optimization for a specific application in the battery settings.
- 📲 Meizu: In Flyme OS, the permission is often hidden in the "Application permissions" section in the phone manager.
On custom firmware from Chinese brands, Android system settings are often duplicated by their own security utilities. Look for the switches there.
Radical measures and resetting settings
If none of the software methods helped, and the “On top of other applications” function remains unavailable, the system may have experienced a critical failure of the access rights configuration files. In this case, the only working option is to return to factory settings. This step will delete all user data, so you need to back up important information in advance.
Before performing a reset, try clearing the partition cache Wipe Cache Partition via Recovery mode. This is a safe procedure that does not delete personal files, but can correct errors in system logs that block permissions. To enter Recovery, you usually need to hold down the combination of the volume and power buttons when the device is turned off.
If clearing the cache did not help, perform a full reset (Factory Reset). After setting up your device for the first time, do not restore all applications from a backup at once. Install the problematic application manually and check the function. This will help you understand whether the conflict is caused by some other previously installed software.
⚠️ Attention: Resetting the settings will delete all photos, contacts and messages not saved in the cloud or on an external memory card. Be sure to make a backup before starting the procedure.

Frequently asked questions (FAQ)
Why is the "On top of other applications" button gray and not clickable?
Most often this happens because Another application is currently active, which is already using this right and blocking the screen. Try closing all recent applications or rebooting your phone in safe mode.
Is it safe to give permission to overlay windows to instant messengers?
Yes, for instant messengers (Telegram, WhatsApp, Viber) this is necessary for pop-up notifications and chat heads to work. This is a standard feature, but it should only be provided to trusted applications from the official store.
Is it possible to enable this feature without a computer and ADB?
In 90% of cases it is possible through standard settings or the manufacturer's security settings. ADB is required only in rare cases of system errors or deep blocking by the smartphone shell.
Does this setting affect battery consumption?
Resolution itself does not consume battery. However, applications that use window overlays (for example, persistent widgets or voice recorders) consume power because they keep the interface layer active.
What should you do if the function disappears after an Android update?
After major updates, the paths to the settings may change. Use the search in the settings menu. If the problem persists, clear the Settings application data in the application management menu.
