For reasons unexplained, I loaded Google Device Manager. Near the end of the installation, when I got to the screen where it lists all of the things that the IT team can do, and that the camera was going to be disabled, I tapped Cancel.
That took me back one screen. I tapped the X in the upper right and exited the installer. However, now I have a continual triangle notification in the upper left of the screen, When I view it, it says "Account Action Required" and my e-mail address. When I tap it, it takes me right back to the screen after had tapped Cancel (above).
If I uninstall from Google Play, it comes back after I reboot.
How do I kill this installer for good?
