What will Galaxy S9 feature?


In the US, Samsung will use Qualcomm's Snapdragon 845 processor -- and it's expected to be blazing fast compared to last years Snapdragon 835 chip.

Fingerprint scanner

One of the loudest complaints about the Galaxy S8 and Galaxy Note 8 was the placement of the fingerprint reader. In order to make room for the bigger display Samsung now uses, the sensor was moved to the back of the phone. Only, instead of putting the sensor in the middle of the phone, as most of its competitors do, the sensor was placed up high, next to the camera.With Galaxy S9, however, Samsung moved the sensor closer to the middle of the back -- just underneath the camera.

We first saw a glimpse of the new fingerprint sensor location when the company announced the Galaxy A8 (2018).

Facial recognition

Samsung has featured both facial recognition and iris-scanning technology in its phones for a while now, but the technology has been nowhere near as complex as Apple's Face ID feature on the iPhone X.

With Galaxy S9, Samsung has Intelligent Scan. The new feature will use both iris scanning and facial recognition to unlock your device.


The Galaxy S9 will boast a super slow-mo mode and a super-speed, dual-pixel, 12-megapixel camera with apertures of f1.5 and f2.4. Changing between apertures is done automatically, depending on the amount of ambient light.

The Galaxy S9 Plus is the only model that comes with dual cameras on the back of the phone. One camera captures wide-angle photos using the dual aperture module. The other lens is a 12-megapixel telephoto lens.

Stereo speakers

Samsung has finally added stereo speakers to the Galaxy line. The speakers are tuned by Dolby Atmos, and accompany a 3.5mm headphone jack.

Apple's iPhone line has had stereo speakers for a few years now, and the additional output makes a huge difference when listening to music or talking over speakerphone.

Business features

Software improvements

The S9 and S9 Plus launch with a few new software tricks. Primarily, Android 8.0 Oreo is installed out of the box. Additionally, AR Emoji creates a 2D image of you, then uses the front facing sensors and camera to mimic 100 different facial expressions.
