Unidentified icon

[AlwaysNewb]

I see a status bar icon appear on the left briefly. I think swipe down is disabled while it is shown. It's a door with an eye. I've checked icons for all the apps I have running, and haven't found it. I've searched help > icon glossary several times. I've googled android forums for days without finding out what it means. When I try to take a screenshot, the screenshot doesn't include the status bar, so I can't show you the icon. I've listed my running apps below.
