I wouldn’t get too excited. I purchased a galaxy xcover 6 pro at launch. It is a recent device with a removeable plastic back cover with a gasket on it to preserve the IP68 rating, much in the same style as was popular up to the galaxy S5.

It seems like they forgot how to make that design work, because the first time I got caught in the rain it died an immediate and very hot death.

There are many other ways to carry out this design but they make the device a bit thicker which manufacturers are going to absolutely hate.
