Samsung S21 Plus Display

Samsung is renowned for their displays and the Galaxy S21 Plus 5G is no exception, thanks to its dynamic 6.2-inch Infinity-0 display, 1300 nit screen at peak brightness and incredible resolution. Gamers can benefit from a 120Hz refresh rate that’s sure to keep them ahead of competitors, while the intuitive in-display fingerprint works to keep your data secure, ensure convenient access to your apps and keeps your mobile wallet just one touch away.

Samsung S21 Camera

The only thing better than one great camera is three high-quality cameras that will transform any amateur selfie snapper to a pro photographer. See more of what you love with the 12MP wide lens, keep things up close and personal with the 64MP telephoto lens, or broaden your horizons even more with the 12MP ultrawide lens with a 120 degree field of view. With 3x hybrid zoom on the rear camera or an incredible 10MP front camera, it’s easy to get those perfect social-media ready snaps in every situation.

Samsung S21 Plus Design

Things don’t get much more appealing than the out-of-this-world design of the Galaxy S21 Plus. Whether you’re a fan of the Phantom Grey, Phantom White or Phantom Violet, there’s an option to suit every aesthetic. And whichever variant tickles your fancy, it’s easy to keep your phone looking its best thanks to the super-tough Gorilla Glass Victus that’ll protect it from everyday wear and tear.

Samsung S21 Plus Performance

The Samsung Galaxy S21 Plus 5G supports Android 11 - the very latest operating system - meaning you can enjoy huge benefits like Android Auto to improve long car journeys. Other perks include faster downloads, high-quality streaming and more responsive gaming thanks to a killer combination of speedy 5G tech, the powerful 400mAh battery and Samsung’s impressive Exynos 2100 processor.
