At the beginning the launcher-manager acted a bit weird (started FLauncher on every home button press) but a reboot with power off did solve that. Now the launcher starts with boot and stays. Ever since I’ve never had issues. I use an external USB DAC to feed my vintage HiFi tho.
You gain a clean interface a Unsplash wallpaper selector and a nice screensaver (galaxy generator rocks) :)
That’s not on Nvidia but the fault of Google tho (they use stock Android TV) you can just use another launcher and set it to auto start ( not like the Fire Stick where they barred that option with updates sigh).
