    Quad-Lens Camera

    One, two, three, four… the Samsung Galaxy S23 Ultra gives a whole lot more in the camera department, with a 12MP Ultra wide lens, a 200MP Wide lens, and two 10MP telephoto lenses packed in to offer the ultimate pro experience. Photos and videos after dark are a breeze thanks to AI Enhanced Nightography for sharp detail in every shot, and even the shakiest setup will be no problem with adaptive video digital image stabilisation on your side.

    Stunning Design

    Tough and elegant, the Samsung Galaxy S23 Ultra is built to last with Corning Gorilla Glass Victus protecting the front and back alongside a sleek Armour Aluminium frame in a choice of four gorgeous shades: Green, Phantom Black, Cream or Lavender. Of course, it wouldn't be Ultra without the ever-handy S Pen on board for total precision and flexibility in everything you do.

    Dazzling Display

    We love a big screen, and the 6.8-inch display of the Samsung Galaxy S23 Ultra isn't just impressive in size, but in specs too. Using adaptive Vision Booster and QHD+ Dynamic AMOLED 2X tech, you'll find it's hard not to get immersed in your favourite shows and games thanks to bright, crisp images and a smooth 120Hz scrolling experience.

    Powerful Performance

    Playing, working or playing at work, everything will run smooth as silk with the Samsung Galaxy S23 Ultra, thanks to the power of its Qualcomm Snapdragon 8 Gen 2 Processor. Developed to dynamic gaming and featuring an improved cooling system, you'll never run short on power – especially not with a huge 5000mAh battery on board.
