The display and body of the Galaxy S9 and S9+ come together to establish a sense of unity. Samsung added ergonomic comfort to each component of the device and refined the overall design to maximize its aesthetic appeal. They reduced the length of the top and bottom ends with a smaller bezel and concealed the sensors for deeper visual immersion. The height and width of the keys were adjusted for easier one-handed use. The curves of the sides were reduced for a more stable and comfortable grip. The two camera holes on the back were vertically aligned for a slimmer & more stable look. The fingerprint sensor is closer to the center for enhanced reachability.
