With the S8 Ultra it worked conditionally well probably it will also work but without trying it out I would not buy it

Yes, no problem

Oops, I just saw that my question is answered in the product description...

Thank you very much for pointing this out. We will gladly forward this internally to the responsible department and hope that this will be rectified in a timely manner.
