It seems strange that I can’t officially play stadia on my Tab S6 but all the Samsung s series phones are fully supported?.
Also are they working on hdr support on chrome?
this could have many reasons. Please follow the Stadia team for example on Twitter to stay up to date about new Stadia-enabled devices! 🙂 http://twitter.com/googlestadia
