Any one elses screen not being fully used when playing games I have two thick borders on both sides when playing games and it's not even centered to be honest.

Hi @Kingkiser 

you are not the only one. I Think that the games just support the "standard" tv or pc aspect ratio of 16/10 or 16/9?

You might want to give feedback to the Stadia team using your app with informations about the phone, etc.
