How can I control my ps4 / xbox one without a controller?

My two controllers are broken, there's no way to control them wanted to watch Netflix on one of the consoles

You can easily control the Xbox via the app on your Android or iOS device. All you have to do is log in to your Microsoft account and connect to the console.

It's very easy

But I have to do an update, I realize that it works with it too

If you have a newer Smart TV:

When I connect a console to myself, it is recognized as such. I can then control the console with the remote control of the TV.

Should work
