Mobile works, but warzone does not. Any game that requires the device to use a validated version of android or not be rooted will not work. COD:Mobile will not natively work with built in controls. You will need to pair a Bluetooth controller and that will let the built in controls work. Or you can use the keymapper feature, which I find to not be accurate enough to play competitively.
They make retro gaming handheld systems. They used to be cheap pieces of plastic that were overpriced, but now make quality products that are reasonably priced. I really like them.
