On the Shield TV I cannot get Daydream to work even when Kodi is running in the background. I have tried all options for the Kodi screen saver but Daydream will not work until I exit Kodi. I am using v17, beta 2 but I got the same behavior with v16. I posted this in the Shield TV thread and someone recommended disabling Daydream, killing the Daydream process, and then re-enabling Daydream but unfortunately this still does not work for me.
