Yuzu Nintendo Switch Emulator is (best to use ‘was’, you’ll know in a bit why) the best emulator that you can use on your Android phone and play Nintendo Switch games.

An emulator is now available for Android smartphones that let users play Nintendo Switch games on mobile phones.

But you can use the Pro Controller similarly. So, if you find you have one lying around, it's a complete breeze to set up on your Android phone or tablet (if you are running Android 10 or later).
