In the latest versions of the mobile operating systems Android 6 (Marshmallow) and 7 (Nougat), users faced a completely non-standard situation when, when trying to install an application, the system for no reason gives an error message that states that overlays are detected , and before installing the program, you need to disable permissions.
What is the reason for this phenomenon and how to remove overlays on the "Android", read on. As a rule, the procedure for disabling this function is quite simple, but on different devices from different manufacturers, the access paths to the section for its deactivation may vary slightly.
What are overlays in Android 6 and 7?
Before you start considering the problem of how to remove overlays on Android 6 or in the seventh version, you first need to familiarize yourself with what this function is, why it is needed and why it causes errors.
As it turns out, the developers of the sixth modification of the Android operating system tried to add to the system a certain additional element of the comfort of working with installed applications, consisting in the fact that some one application that the user is working with at the moment is active, and all the rest function as if in the background, but they appeared on top of the main window of the active program if some actions and processes are activated in them.
For a more simplified understanding, you can use the Facebook messenger as an example. Suppose you talked with someone until a certain point, but then you needed to launch another applet (say, look at some important information on the Internet). The messenger remained active, but works in the background, and its minimized window is in the foreground. As soon as a message comes from your interlocutor, the program instantly appears on the screen, and on top of the application with which you are working. This is an overlay.
On the one hand, it seems to be a good idea. On the other (as it often happens) - the pancake turned out lumpy, since this function can cause a bunch of errors.
How does the error manifest itself
The question of how to remove the overlay effects is left aside and see how this failure affects the user.
The fact is that a crash can occur even when installing a new applet, when the user has a chat in the chat or uses the same messenger. When trying to install a new application, a request for special permissions is first issued, and the system itself responds by prohibiting changes to the parameters. So it turns out that there is a conflict between the installed program and the system (although in fact, a completely different applet is to blame for this, for example, the same messenger).
It goes without saying that the question of how to remove the overlay from the application on Android can be resolved by shutting down the culprit program or by completely rebooting the device. But do not forget that the same messengers or optimizers-cleaners are often at startup and start with the system. Thus, if activity is detected in them, you will still receive an error message. And it is sometimes impossible to disable some startup items using regular Android tools.
To do this, you will have to install an additional applet, which, in turn, can also cause a similar effect or disable the system function in general.
Overlays detected: how to remove the appearance of a message on the “Android” in the general case?
Nevertheless, several solutions to this problem can be proposed. Usually the question of how to remove overlays on the "Android" on most devices is solved quite simply.
You must enter the settings menu and go to the applications section. In the upper right corner, a button with a gear is pressed, and then the item “Above all windows” is selected.
Next, a list of all programs that use overlays is displayed. You can disable them by simply moving the slider from “Yes” to “No”. But this, alas, applies only to custom applications. And applets like a calendar or a camera cannot be configured in this way.
Disable overlays on Samsung devices
The question of how to remove overlays on the "Android" on the devices of this manufacturer in the first stages does not differ from the above proposed method.
The only difference is that in the application section, you must first go to the appropriate dispatcher, click the options button, and only then the “On top of all applications” menu will appear.
But there is an interesting detail. You can deactivate the function for each individual applet or disable its use at all, which looks much more preferable, since the system settings can “fly off” very often when the device is rebooted.
Disabling overlays on LG devices
In principle, for the devices of this manufacturer, the problem of how to remove overlays on the "Android" is also solved easily.
Only for access to the deactivation section of this function, it’s not the dispatcher’s menu (as on Samsung devices), buttons in the form of a gear or a link like “More” or “More”, but the “Application Settings” menu.
Instructions: how to remove the application on the "Android", which causes an error?
Finally, a few words about the situation when you do not want to completely disable the function (but some unnecessary system application still uses it constantly), or you need to delete it altogether (do not disable it, namely delete it).
One cannot do without root rights in such a situation, since Android itself prohibits deleting system applications. Nevertheless, there is a solution. You can find a lot of programs for receiving or firmware with root rights, but not all of them work correctly, often causing such malfunctions that the whole system turns out to be inoperative.
As one of the proven and reliable applets, you can recommend Kingo Root. And as an optimizer, which works once and then does not interfere with the functioning of the system, - Root Booster.
After installing Kingo Link, no one will stop you from digging into system applications, finding the appropriate service there (something like Draw Over or Screen Overlay) and removing it completely and irrevocably.
If we are talking about a user program, you can do without it, and delete it in a standard way with preliminary clearing the cache and erasing all data. But that may not work.
Conclusion
If none of the methods described above helps or it is impossible to remove programs that use overlays, you will have to use “heavy artillery” (a complete reset to factory settings), having previously performed at least a backup.
However, one can apply a no less effective method, namely, switch to a lower version of the operating system, say, the fifth modification. Here certainly errors with overlays will not bother you.
