Samsung Electronics unveiled its new flagship Galaxy S9 and S9+ smartphones in Barcelona ahead of the start of Mobile World Congress. The phones offer an upgrade to the camera, storage and speed compared to the S8, including new AR options, and will be slightly more expensive than the previous generation from Samsung, according Telecompaper. The new Galaxy phones go on pre-sale 25 February and will reach stores 16 March, available in a choice of black, grey, blue and the new colour lilac. The recommended prices are EUR 849 for the S9 and EUR 949 for the S9+, or around EUR 50 more than their predecessors at launch.
Similar in appearance to its predecessor, the new Galaxy S9 comes with a 5.8-inch Super Amoled screen with 18:5:9 screen ratio and QHD+ resolution (1,440x2,960 pixels). The S9+ has a larger 6.2-inch screen with the same resolution and screen ratio; both are "near bezel-less".
The phones will run Samsung's own Exynos 9810 processor in certain regions and the new Qualcomm Snapdragon 845 in other parts of the world. The same as the previous generation, the S9 comes with 4 GB RAM, while the 'plus' model includes 6 GB. Both have internal storage of 64 GB plus support for the new generation of microSD cards up to 400 GB. 
Thanks to the new processor, these will be the first smartphones with support for LTE Cat 18. With 4x4 MIMO and carrier aggregation over five bands, that means theoretical speeds of 1 Gbps download. 
Samsung has also updated its Dual Pixel camera, with an aperture of f/1.5 for super-low-light photos. Samsung said this means the lens can let in 28 percent more light than the Galaxy S8 series. The S9+ comes with a dual back camera, both 12 megapixels, with dynamic aperture that adjusts between f/2.4 and f/1.5 depending on the light conditions. 
Other new features on the camera include Multi Frame Noise Reduction, which compresses multiple images into one photo to reduce noise. An option for slow-motion filming on the video camera includes motion detection to start filming and a range of editing and background music features for videos. Samsung also added more options for creating AR emojis from the user's photos and videos. 
With Samsung's digital assistant Bixby, S9 users can also access a range of augmented reality options on the camera, using also deep learning technologies from Samsung. With real-time object detection and recognition, Bixby can generate information directly on top of the image that the camera is pointing at. Users can translate foreign languages and currency in real time by pointing the camera at the text, as well as access online information about the objects in view, such as where to buy products in the real world. 
Samsung will also be loading its new SmartThings app on the phones to encourage integration with its other consumer electronics and smart home products. For the business market, the company introduced an upgraded DeX Pad porting dock for the phone, the Knox 3.1 security platform and an option to use a second fingerprint for accessing the secure folder. The company also upgraded the optical sensor to allow health-conscious users to measure their 'heart load factor' with the device.
