BOOM. You're done. iPhones try to act like it's "just a website bookmark" because they want everyone to go through the App Store but really it functions just like an app... Full screen, moveable icon on your home screen. All of it.
Enjoy.
Install the Channel 3 app from the Google Play Store.
I've gotta say, this isn't necessarily coming based off of anything you can play right out of the app store. Rather, it's due to a combination of things like the Steam Link and Gamepass apps, cloud gaming, and the awesome mobile controllers (my go-to is the Razer Kishi). I've played a bunch of gamepass stuff I wouldn't have otherwise had the time to get to if it was a matter of sitting at my computer and using valuable "real gaming time", and over the steam link I've managed quite a few hours in things like No Man's Sky.
Not sure I would use this setup for any kind of online competitive multiplayer gameplay, but for the more casual or single player games, it's amazing.
