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+.

While the 12-megapixel rear camera has continued since 2016’s Galaxy S7, Samsung introduced a new Super Speed Dual Pixel camera, and the S9+ has a second camera lens. 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.

You can make a setting for this feature kicking in automatically or manually. The automatic mode detects a motion to start Slo-Mo recording.
