If you want to stream your favorite streaming platforms like Netflix U.S on your Roku device, you can try casting from your Android device. But do keep in mind that this method might only work on certain Android devices.
Access your device and launch the ExpressVPN app.
Next, tap the location picker and then select your desired location (The U.S for example).
Now, on your Android device, launch any VoD streaming app (e.g. Netflix).
Select any show or movie you would like to cast on to Roku.
Bring down the control center to access Quick Settings. Tap on Screen Cast and your device screen should now begin to mirror onto your Roku device hooked up to your TV.
