Kaspersky Internet Security for Android

1. In the list of apps installed on your device, locate the app that is changing your screen color or brightness. If you're not sure which app this might be, see whether an app from this list is installed on your device.
2. Open the app.
3. Tap Off.

Apps that change the screen color or brightness can be harmful to your device, as they can create a fake button and disguise it beneath another one, e.g. under the Allow button in the image below. 

By clicking Allow, you think that you are granting the app permission to access your media files, but you may actually be allowing a malicious app to take control of your device.

The Self-Defense feature in Kaspersky Internet Security for Android prevents it from being switched off by malicious apps: the Kaspersky Internet Security for Android interface will be blocked while a potentially harmful app is running. 

If the issue persists, submit a request to Kaspersky Lab technical support via My Kaspersky. Please include a detailed description of the problem.
