Issue
When attempting to install an app through the DeployGate app, I encounter the following error message: “Looks like another app is blocking access to Google Play. Turn off any apps that might be drawing over the screen and try again.”
Solution
As part of Google Play’s security measures, apps with a screen overlay function prevent other apps from being installed. The following types of apps are affected.
Blue light blocking filter
Battery level display
Overlay-type app launcher
If you know which app is causing the issue, you can either shut down the app or temporarily disable the screen overlay function. Try installing the new app again.
If you don’t know which app is causing the issue, go to “Settings” → “Apps and notifications” → “Detailed settings” → “Special app access” → “Display over other apps” and disabled permissions for any app that is set to “Allowed,” “On,” or “Yes.” Try installing the new app again.
