The Galaxy S21 Ultra sports a generous 6.8-inch Infinity-0 display that’ll elevate your next streaming session to the next level. When paired with the super-high resolution, 1600 nits at peak brightness and 120Hz refresh rate, you’ve got yourself a seamless mobile experience that’s perfect for gaming. And that’s not all - the Galaxy S21 Ultra also offers improved security via the advanced in-display fingerprint scanner that allows you to unlock your device, access apps and authorise payments with ease.
One of the top perks of the Samsung Galaxy S21 Ultra is the top mobile performance provided via the Android 11 operating system. Android Auto is ideal for long commutes as it allows you to hook up your favourite apps to your car from your phone, while Android 11 also enables you to control things in your home, including the heating - perfect for those lazy lie-ins. Samsung’s speedy 5G tech and Exynos 2100 processor work together to improve download speeds, provide higher-quality streaming and offer more responsible gaming, while the powerful 5000mAh battery keeps you going for longer.
The Samsung Galaxy S21 Ultra packs a punch with four incredible pro-grade lenses that let you capture every moment through high quality photos. The whopping 108MP wide camera is perfect for selfies, while the 12MP ultra-wide lens is best suited to big group photos. With 10MP telephoto and periscope lens, 1-x optical zoom and a 40MP front camera, the Ultra truly raises the bar when it comes to snaps and selfies.
It’s not just the display that exceeds all expectations - the Galaxy S21 Ultra 5G also boasts an attractive design thanks to its appealing glass screen and sleek aluminium frame. Rest assured that these aesthetics don’t come at the expense of durability, as the phone comes equipped with Gorilla Glass Victus and an IP68 rating for water resistance. And whether you’re a fan of Phantom Black or Phantom Silver, you can get more out of your Galaxy by choosing a colourway that suits your style.
