It's not an option, even if they pretend it to be one: if I click the text "install without scanning", nothing happens. I must accept the big button that uploads the app for a scan. It's none of their business.
ADB is no alternative for me, because it's easier for me to send a websocket command to my 9 devices (mostly dashboards) so that they download the file and start the upgrade process, so that I then only need to press the "upgrade" button manually on each device. Remove the dashboards from the walls, just to plug an USB cable in them, to upgrade the apps?
