At first glance, the Galaxy S9 could look just like the Galaxy S8, which expanded the screen-to-body ratio, slimmed down those bezels and stretched the phone to be a little taller and more narrow. Look a little closer, though, and a few rumored differences hint that the Galaxy S9 might not get a 100 percent cookie-cutter design. 

Keep in mind that none of these rumors have been verified, and that Samsung has not responded to a request for comment.
