In that situation, I’d just go ahead and disallow all of them, then re-enable them on an as-needed basis. Of course, that’s not foolproof-in some instances there may be more than one app drawing on the screen, which can be incredibly frustrating. The list in the screenshot above shows all the apps that have permission to draw on the screen, but if you can figure out which one is actually drawing on the screen when you get that error, you can just disable that one and move on.

What passive apps do you use that run in the background? Similarly, apps like CF.lumen and Twilight draw on the screen when enabled, so you’ll need to pause or disable those services to get rid of the screen overlay error.

What apps have you been using recently? As mentioned above, Facebook Messenger draws on the screen for chat heads, so if a chat head is actively running, it’s most likely your culprit.Ideally, you’ll know which app caused the conflict, and you can disable just that one. You could disable every single one, but that could be super time consuming, especially if you have dozens of apps installed that can apply overlays.

Now, sometimes when this error is generated, it includes an “Open Settings” link that sends you directly into the “Draw over other apps” menu. The rough part is that each app has to be toggled manually-just tap on an app, slide the “Permit Drawing Over Other Apps” toggle, and go back. In the example below, I’m using Twilight-a “night mode” app-which uses a screen overlay to do its thing. So, if you install a new app and launch it for the first time while also having a conversation over a Facebook Chat Head, you’ll get an error as the new app tries to request its permissions.
