Design and Build

The Samsung Galaxy S21 Ultra build is similar to that of the Plus with Glass front (Gorilla Glass Victus) which is hard enough to survive drops but a screen protector is still required. The back is made from the same Gorilla glass that is on the front and an aluminium frame. It also has IP68 dust/water resistant (up to 1.5m for 30 mins) rating for those oops moments when the phone is dropped in water. The phone is quite large at 165.1×75.6×8.9mm and weighs in at 227g, which is not so comfortable for small hands.


The phone’s screen is a huge 6.8″ Dynamic AMOLED 2X screen with a refresh rate 120Hz it is also the only one in the series that has a 1440p resolution. It also comes equipped with HDR10+ support and has a peak brightness of 1500 nits to make it a brightness monster that can be viewed well under direct sunlight. At 1440x3200px resolution and an aspect ratio of 20:9 with 515 pixels per inch, even the smallest of details can be visible. One of the features is an always-on display which will come in handy for those in need of long viewing.

User Interface and Performance

The Samsung Galaxy S21 Ultra 5G comes installed with the latest Android 11 operating system skinned with Samsung’s own One UI 3.1. The new One UI 3.1 does not interfere too much with the native Andriod 11 with is welcome as the two now work well in tandem. Samsung Galaxy S21 5G UI

The user interface feels fast thanks to the Exynos 2100 (5 nm) with Octa-core CPU (1×2.9 GHz Cortex-X1 & 3×2.80 GHz Cortex-A78 & 4×2.2 GHz Cortex-A55) processor. Everyday use of the Samsung Galaxy S21 Ultra will so much better. Gaming will also be a breeze with the Mali-G78 MP14 GPU. Combined with the 120Hz refresh rate of the screen the gaming experience will be so much more enhanced.

Camera Quality

The Galaxy S21 Ultra is the most camera focused on the S series. It comes equipped with a main quad rear camera setup,  Wide (main): 108 MP, f/1.8, 24mm, 1/1.33″, 0.8µm, PDAF, Laser AF, OIS; Ultra wide-angle: 12 MP, f/2.2, 13mm, 1/2.55″, 1.4µm, dual pixel PDAF, Super Steady video; Telephoto: 10 MP, f/2.4, 70mm, 1/3.24″, 1.22µm, dual pixel PDAF, OIS, 3x optical zoom; Telephoto: 10 MP, f/4.9, 240mm, 1/3.24″, 1.22µm, dual pixel PDAF, OIS, 10x optical zoom. Shotting in daylight out of the Galaxy S21 Ultra’s main camera is very appealing. You get a wide dynamic range and a healthy dose of colour saturation, though that last bit has been tuned down ever so slightly.

The night shots and low light image quality is quite good. It exposes well and exhibits a wide dynamic range even before resorting to Night mode processing. The selfie camera is a 40 MP, f/2.2, 26mm (wide), 1/2.8″, 0.7µm with PDAF. The S21 Ultra goes for much sharper and grittier detail and the Dynamic range is nicely wide, and backlit scenes aren’t an issue either.

Video Recording

The phone’s video recording capabilities are of some high calibre owing to its 8K capabilities. Yes the Samsung Galaxy S21 Ultra can record videos in 8K meaning you might need to get the one with more storage as there is no expandable memory card slot. It features rear camera recording at; 8K@24fps, 4K@30/60fps, 1080p@30/60/240fps, 720p@960fps, HDR10+, stereo sound rec., gyro-EIS;  and front camera at; 4K@30/60fps, 1080p@30fps.


With 128GB, 256GB or 512GB of storage so there will be no need to delete your favourite photo moments. The flash storage comes equipped with UFS 3.1 which improves the read and write speed to complement the 5G. The Galaxy S21 Plus does not have expandable storage via the SD Card which will not please a few heavy video recording users. And with 8K recording, storage can be used pretty fast. It comes with 12GB or 16GB of RAM depending on the variant to aid in the multitasking and Dex support.

Battery Life

The Samsung Galaxy S21 Ultra comes equipped with a 5000mAh battery capable of fast charging at 25W with USB Power Delivery 3.0. It also has wireless charging at Fast Qi/PMA wireless charging 15W and can reverse that wirelessly at 4.5W.
