That's not a bad thing at all. It means the camera "notch" stays out of the way, and that the edge-to-edge screen feels natural. And yes, you still get a headphone jack. Where Apple dramatically retooled the iPhone X by removing its signature home button and adding a screen notch, Samsung opted for an unbroken continuum. The Galaxy S10 simply picks up where the Galaxy S9 left off.
