However, a patent suggests it’s one Samsung’s looking to remedy for the Galaxy S9. >Found by GalaxyClub, a Samsung patent application shows a fingerprint scanner built into a little notch at the bottom of the screen, a lot like the notch on the Essential Phone or to a lesser extent the iPhone X, but at the bottom rather than the top, and housing a scanner rather than a camera.
