Hello, The controller is bluethoot so it will work with the tablet, I tested with the Galaxy tab S6 ( IOS is not supported) but I don't know of any tablet adapters available from Razer. This product is made for 3 phone models specifically and to use it coupled with other models you will have to find adapters specifically for the model in question on the web.

No only for the S10+ model. Greetings

Compatible with Android (7.0+) and PC with Bluetooth support (Windows 8.1+), latency less than 14 ms, Razer Gamepad App (Andriod 8.0+).

On the Razer website they say you have to have Android 8.0 or higher, so it should be compatible.

Since the ASUS ROG Phone II works with Android 9.0 Pie, you should be fine with this controller.
