As previously mentioned a S20+ full-body back-over-front case was expected to fit the screen, but too long.
This morning this arrived, and well it does fit the screen sideways, and is too long,
BUT it makes the edges of the screen out of reach, and that what not what I was hoping for.
On the other hand the edge sticking out makes it easier to push up the screen.
It is not for me, so I have not bothered to try to cut and melt it shorter....
