I have two devices now, both running v 1.8-104. On separate occasions, both TV units were showing a completely green screen. I had to reboot the android DSDevice.
Maybe these devices need some sleep time. That said, I am unable to locate commands that I can use to schedule periodic reboot cycles for these android units if they cannot stay awake for the duration. I am using the Xibo Digital Signage interface.
The Xibo server is locally hosted.
