I wanted to know if the stadia remote is compatible with my mobile, xiaomi redmi note 8 pro via bluetooth or wifi
Hi @Danieru
it is not officially supported. See list: https://support.google.com/stadia/answer/9578631
Nevertheless, it could be possible that it will work.
See this Stadia post which shows that a user is playing Stadia using your device: https://www.reddit.com/r/redminote8pro/comments/hd65kj/google_stadia_on_my_redmi_note_8pro/
