Yes, but IP67 is not nearly as water resistant as IP68, which all modern phones are for the most part.

I'm not knowledgeable enough to know if IP68 could be achieved in a phone without glue. There's no clamping mechanism for the backs, they're just press-fit with small clips.

You forget the Xcover and active lines which do IP68. They stopped making Galaxy active phones but the tabs are still there. The Xcovers too.
