Does Amazon Fire TV Stick 4K Plus (newest model) support smarttube?
I am asking about Plus and not Select.
Amazon answered it runs on FireOS and not vega OS

4K Plus Sticks should run on FireOS, so this should be a yes.
But they may be not much longer aivailable to buy...

I bought it and can confirm that Kodi (ATMOS works movie files) as well SmartTube works nicely on this device.
Amazon android bridge installed, I can use fire tv remote to do voice search too.
