Samsung Galaxy S9 and Galaxy S9+ were officially unveiled ahead of the Mobile World Congress (MWC) 2018 in Barcelona on Sunday. As expected, the biggest improvements are in the camera department, with a variable aperture sensor on the primary rear camera on both phones, and a dual rear camera setup on the bigger Galaxy S9+. The phones are being launched in Midnight Black, Coral Blue, Lilac Purple, and Titanium Grey colours, and will be available from March 16 in select markets. No pricing information has been provided.

Samsung Galaxy S9 and Galaxy S9+ specifications
The highlight of the Galaxy S9 and Galaxy S9+ is the dual aperture setup on the primary rear camera sensor, which is capable of shooting at f/2.4 when there’s ample light, but can switch to f/1.5 in low-light conditions. Samsung says this enables the Galaxy S9 and Galaxy S9+ to capture 28 percent more light compared to the Galaxy S8, adding that a new multi-frame noise reduction feature results in up to 30 percent less noise compared to the previous flagship.

The other headline feature of the Samsung Galaxy S9 and Galaxy S9+ camera is the super slow-mo camera that works similar to what we’ve seen on Sony’s recent flagships. The phones are capable of recording 960 frames per second, which means 0.2 seconds of footage is stretched out to 6 seconds when you are playing it back. You can export this footage as a GIF or use it as an animated wallpaper on the phone.

The final camera-related improvement on the Galaxy S9 and Galaxy S9+ is the introduction of Bixby Vision in the camera app that will now offer live translation features, the ability to recognise the buildings and other places in a frame, and even look at the food in your frame and provide information like the amount of calories in the item, a feature that will be available only in select regions.

Another upgrade is the presence of dual speakers on the Samsung Galaxy S9 and Galaxy S9+ (tuned by AKG Acoustics) with one downwards firing speaker, and the earpiece doubling up as the other channel. This setup, Samsung says, results in sound that’s 1.4 times louder than the Galaxy S8. All this is backed by Dolby Atmos for surround sound, with a toggle in Quick Settings enabling this enhancement for any kind of audio content, according to Samsung.
