So I bought a Beelink GT1.These issues with all the S912 boxes and Kodi 17. Which is bette version.Mine wont be coming for 2 weeks or so.Just wanted to know before it got here.
Stay with 17 from the Google play store. Or download older 16 final from Kodi download page or use the fork SPMC…the former Kodi android maintainer, Koying.He says on site…”As far as I’m concerned, Nvidia Shield has basically cornered the market, so is my main development device. More generally, Android TV devices, amlogic devices and Amazon FireTV might be getting some love

Says ..Note 1: As of 16.5.0, Android lollipop (API 21) is required.
