The Galaxy S9 and S9+ have the same size as S8 and S8+ respectively. The S9 has a 5.8-inch screen, and the S9+ has a 6.2-inch display. You may notice that they are slightly heavier than the predecessors, probably because of the additional components which offer the new camera features.
The same displays as the predecessors mean that you will have the same Infinity Display on S9 and S9+. 1440p Super AMOLED displays with an 18.5:9 aspect ratio hasn’t been changed. However, Samsung says that it’s brighter than the S8 and S8+.
There are noticeable changes on the back. The fingerprint sensor has been moved from the right of the rear camera to below the rear camera. As a result, you may be less likely to touch the camera lens and put your fingerprint on it.

Camera

The main 12-MP lenses have a variable aperture that can switch between a f/1.5 and f/2.4 aperture depending on brightness in the environment. The S8 has a fixed aperture of f/1.7. The wider aperture can help letting in more light so you can take pictures in dark environment. The second camera lens on the S9+ is a 12-MP telephoto lens which offers 2x optical zoom.
Another new and significant camera feature is Super Slo-Mo video capabilities. It can slow down to 960 frames per second at 720p resolution. You can make a setting for this feature kicking in automatically or manually. The automatic mode detects a motion to start Slo-Mo recording. But, because of the sensitivity of motion sensor, the automatic mode is not always successful. If you know the moment to capture Slo-Mo video like blowing birthday candles, throwing a surprise party, or playing a prank on your friend, it’s better to use manual mode.
