We've been collecting a long list of features that the Samsung Galaxy S9 is rumored to include when it launches next month at Mobile World Congress, the show for all things mobile.  

Meanwhile at CES, the show for every sort of tech (not just mobile), we saw plenty of innovations that could find their way into future handsets like the Galaxy S9.

Realistically, most of these features would show up well down the line if they do at all, but at least one new technology we saw is a strong bet to appear in Samsung's top-shelf phone for March. If it does, it would fix the Galaxy S8's most maddening flaw.
