When it launched, Google Stadia didn’t have the best of welcomes from the community. It’s hard to say how many people can get it to work, per se. But it seems that the Stadia team is planning on expanding. People can now access Stadia even without Google phones.
Google has announced support for more hardware such as Samsung phones, including Razer and ASUS devices. For those who own a Samsung Galaxy S8, S9, S10 or S20 you’ll be able to use your Stadia subscription for those devices. Razer Phone and ASUS ROG Phone are also now capable of accessing Google Stadia.
Though if you aren’t interested in playing it on your phone, tablets, laptops, and desktops that can run Google Chrome are also at your disposal.
