Three years in, and we bet your Galaxy S21 Ultra is still alive and kicking. But what about its case? Maybe it's time for an external update for your seasoned phone? Thankfully, most of our options are already set up as early as 2021. Even better, perhaps, is that these choices are still plenty and available in our good year of 2024.
Best overall
OtterBox Symmetry Series Case for Galaxy S21 Ultra

This case claims to offer lasting "antimicrobial technology" and durable protection against drops, bumps, and fumbles.

Best premium

This case is supposedly made of high-quality cowhide full-grain leather, and features exquisite stitches for durability and its signature elegant look. For protection, it provides adequate durability against drops, bumps, scratches, and dust, with its outer layer also accented by its suede inner lining. It offers easy access to ports, precise cut-outs, and is wireless charging friendly.
Best budget
tech21 Evo Check Case for Galaxy S21 Ultra
$6.41
A surprising little cheap contender that actually works. Tested to withstand 12ft/3.6m drops, with a special focus on camera and overall phone protection. Featuring "self-cleaning" technology, the product claims to remain relatively clean and germ-free. The slim design includes interchangeable buttons for personalization. Aside from its superb value, users appreciate its durability and slim profile, ideal for those with an active lifestyle.
Caseology Nano Pop for Galaxy S21 Ultra
$15.99
Cheap but still stylish, nuff' said. The Caseology Nano Pop is a high-quality case with a bold two-tone color scheme that offers eye-catching contrast. It is slim yet protective, with an inner defense pattern designed to disperse shock from drops, bumps, and fumbles. Users have praised its smooth and grippy feel, perfect for pocket use, though some have noted issues with smudging.
Spigen Ultra Hybrid for Galaxy S21 Ultra
$12.99
The Spigen Ultra Hybrid case features a TPU bumper and PC back for durability. Raised bezels protect the screen and camera from scratches, and pronounced buttons are easy to use. Its clear design showcases the phone's original look, and the case generally feels great in the hand. A handful of reviews mentioned that smudges and fingerprints can be an issue, however.
SUPCASE UB Pro Series Case for Galaxy S21 Ultra
$24.95
The UB Pro case claims to provide military-grade protection with its multi-layered TPU and polycarbonate construction. It features precise cutouts for easy access, a built-in kickstand for hands-free viewing, and a pen holder designed for the S Pen. The case's design includes a flat back to prevent camera wobble, rubber nubs to prevent sliding, and ample screen protection.
Speck Presidio 2 Grip for Galaxy S21 Ultra
$44.99
The Speck Presidio2 Grip leans on heavy-duty protection, claiming to withstand drops from up to 13 feet. It utilizes a soft-touch, grippy material for secure handling and boasts built-in antimicrobial protection to combat bacteria. However, some users find the very things that make it grippy and secure to be bulky, even making it slightly challenging to remove from pockets.
Arae Wallet Case for Galaxy S21 Ultra
$16.99
The Arae wallet case is well... an entire wallet by itself! Features card slots, pockets for cash, and a magnetic closure. The stand function allows for hands-free viewing. While some users find it eventually too tight when stuffed with all the things it is supposed to hold (five cards + two cash pockets), it remains a budget-friendly option with generally positive feedback on its functionality.
Which S21 Ultra Case is For You?
I am not going to lie; the Arae Wallet Case is one heck of a multi-purpose case that could have potentially beaten our top three picks if it weren’t for the very “jack-of-all-trades, master-of-none” aspect that it is stuck into. Still, if you prefer taking advantage of multiple features rather than choosing the best out of a single option, then all the other Galaxy S21 Ultra cases here are still ripe for the picking.
