does it work with samsung galaxy Fold2 Phone ?

Works with any Samsung or Android phone. It is just tailored towards Samsung Phones with the Hot Keys. Get it, it's worth it.

Will this keyboard work with a Samsung M70b smart monitor?

David, what is the secret to input the passcode with this keyboard on the Samsung smart monitor M70b? The monitor recognizes the Trio 500 keyboard but I have no way to input the PIN to pair up.

Can this be paired with Samsung S22?

I have a S21 and it paired. I'd guess it will pair to an S22.
