No I sideloaded the Tasker APK and set Tasker to reboot each Android unit every night.
It helps to clear memory and helped with stability. Also I rotate in a layout every 30 min or so to wipe the screen.
This is mainly for the RTSP feed layout, as it seems to hang for a bit after a few hours of running non-stop.
Because of these occasional hangs, I’d like to find a more robust Android device for the Xibo client even if it costs a couple hundred.
