Samsung has unveiled its new flagship smartphones, the Galaxy S9 and S9+, ahead of the opening of Mobile World Congress in Barcelona.

The new handsets boast a redesigned camera that the manufacturer claims is its most advanced ever.

The S9 range also features super slow-mo video recording capable of capturing at 960 frames per second, as well as new Augmented Reality Emojis.

The main camera on both models has a dual aperture lens that Samsung says has innovative new low-light technology.

The Super Speed Dual Pixel sensor is capable of combining 12 frames into one image to boost the quality of the photo.

Motion Detection also detects movement in the frame and starts to record automatically.

The S9 has an edge-to-edge 5.8-inch Quad HD+ curved Super AMOLED display, with an 18.5:9 aspect ratio.

The Galaxy S9+ has a larger 6.2-inch version of the same screen.

Both handsets, which were unveiled at a press conference in the Spanish coastal city, have AKG-tuned stereo speakers with Dolby Atmos surround sound.

Smart home device users will also benefit from the new version of Samsung’s SmartThings app which comes installed on both devices.

Not dissimilar to the iPhone X’s Animojis, the new AR Emoji feature analyses a 2D image of a user and then creates a 3D model of their face which imitates their expressions, winks and nods.

Samsung has also beefed up its artificial intelligence assistant on the devices, with Bixby now able to generate information about an object the camera is pointing at and translate foreign languages live.

The S9 and S9+ both carry an IP68 dust and water resistance rating, as well as fast wireless charging capability.

The handsets are powered by Octa-core processors, with 4GB of RAM in the S9 and 6GB in the S9+.

In the memory department the devices come with 64GB out of the box, but the Micro SD slot provides expansion of up to 400GB.

There are three options for unlocking the device - Iris, fingerprint and facial recognition.

The S9 and S9+ will be available here from 16 March with pre-orders opening 25 February.

Those who order before 7 March with receive their devices on 9 March.

Local pricing for Ireland has still to be announced by the operators here.
