Stylish and durable in equal measure, Caseology's Nano Pop series gives your Galaxy S21 Ultra top-tier protection. Its two-tone color finish makes for an attractive design, and the pattern on the inside helps in dispersing the impact of hard falls and bumps. Raised edges around the screen and camera array offer added protection, and there's wireless charging support as well. You can choose from two color options—Blueberry Navy and Prune Charcoal.
Rugged and practical
Arguably one of the most durable Galaxy S21 Ultra cases in the market, ArmadilloTek's Vanguard series conforms to military-grade protection standards. Its multi-layer design allows your smartphone to survive falling from a height of twenty feet, and there's even a built-in kickstand that you can use to prop up the phone for hands-free content consumption. Some of the color options available include black, red, and purple.
Carry the S Pen with ease
Support for the S Pen is easily one of the standout features of the Galaxy S21 Ultra, and this is exactly where Spigen's Liquid Air P comes into the picture. Thanks to its built-in compartment, this case lets you carry both the smartphone and the stylus with little to no effort. Its anti-slip matte surface improves the in-hand feel, and you also get raised edges around the screen and rear camera module for added protection from all kinds of scuffs and scratches.
Thin yet tough
We've been fans of Ringke's cases for a long time and have absolutely no reservations recommending the Onyx series for anyone who wants a slim yet sturdy case for their Galaxy S21 Ultra. It's made with long-lasting TPU material and comes with a grainy texture on the back that enhances the in-hand grip while also keeping away smudges and fingerprints. As with most of Ringke's cases, this one also comes with lanyard holes that you can use to attach neck or hand straps.
Otterbox's cases are renowned for their class-leading durability, and the Symmetry series is no different. From minor bumps to the nastiest of falls, it can protect your Galaxy S21 Ultra from anything and everything. The case's anti-microbial technology prevents bacteria from developing on the surface, thus making things a little more hygienic. Despite being tough, the Symmetry series cases are comparatively lighter than many of Otterbox's other offerings.
Flaunt that design
Want a case that'll protect your Galaxy S21 Ultra while letting you show it too? Look no further than ESR's clear case, which is slim and lightweight. Despite its thin profile, it does an excellent job shielding your flagship smartphone against bumps and falls. The case features raised edges around the screen and camera array for extra protection, and its micro-dot pattern prevents the case from sticking to the phone. Oh, and did we mention it's super affordable too?
Looks good, works better
Speck's Presidio2 Grip is among the best-designed Galaxy S21 Ultra cases you can get, but there's a lot more to this thing than good looks. Capable of protecting your smartphone from up to thirteen feet high drops, it comes with 'Microban' technology that reduces bacterial growth on the case's surface by up to 99 percent. You also get funky patterns on the back that help with the in-hand grip. Some of the color combos on offer include Graphite Gray and Coastal Blue.
Transparent, but better
If you like clear cases but find them a little boring, take a look at Spigen's Liquid Crystal Glitter series. Made with light yet tough TPU material, it comes with a built-in shimmering pattern that makes for a unique and eye-catching design while still allowing the gorgeous back panel of your Galaxy S21 Ultra to peek through it. The case also features reinforced buttons with great tactile response, as well as precise cutouts for all of the device's ports and openings.
Official combo accessory
If you're not a fan of third-party cases and want something from Samsung itself, this is just the thing for you. The top-tier silicone cover protects your Galaxy S21 Ultra from scuffs and scratches, and its fit and finish are as flawless as you'd expect an official accessory to have. Oh, and the case also comes with the S Pen stylus as part of the package, giving you everything you need to have the perfect productivity package.
Customizable and self-cleaning
One of the more interesting Galaxy S21 Ultra cases available in the market, Tech21's Evo Check features custom-developed materials that ensure the case is clean every time you pick it up. It's tested for drop protection from up to a height of twelve feet and comes with a unique design that keeps the camera array protected from damage. Another interesting feature are the interchangeable buttons, which you can mix and match to get a case design that's uniquely yours.
Rugged protection without the bulk
If there's one thing UAG's Monarch shows, it's that rugged cases don't have to look boring. With a stylish yet lightweight build, the case comes with an impact-resistant core and honeycomb traction grip pattern, giving your Galaxy S21 Ultra the best protection against wear and tear. You get responsive and oversized buttons for easier use, while the raised bezels around the screen and primary camera array make for a total protective package. Even with all that, there's full support for wireless charging.
Simple and reliable
Spigen's Rugged Armor is perfect for those who just want a no-fuss protective case for their Galaxy S21 Ultra without any extra bells and whistles. Made from a flexible TPU material, it sports Spigen's 'Air Cushion' technology that helps absorb the impact of falls and shocks. The case's tactile buttons are easy to press the spider-web pattern on the inside helps in enhancing its overall grip. You still get raised bezels around the screen and camera array, along with wireless charging compatibility.
For the best grip
Caseology's Parallax series features a stylish and functional 3D pattern on the back that looks great and helps improve the in-hand feel and grip. The Galaxy S21 Ultra case features a dual-layer construction that involves Polycarbonate and TPU materials. You also get raised edges around the screen and the rear camera system for the best protection against falls, scratches, and just about everything. The case is available in various color options, including Ash Gray, Indi Pink, and Purpli-sh.
Lots of color choices
Made from Polycarbonate, TPU, and rubber, Crave's Dual Guard series of cases can protect your Galaxy S21 Ultra from even the harshest of falls and bumps. The case features a compact build that makes slipping it in and out of pockets a cakewalk. What's more, the Dual Guard is available in various swanky colorways, including Blush, Berry, Lilac, Slate, and Navy. And no matter which color you go for, you'd get a lifetime warranty for that extra peace of mind.
Keep your Samsung Galaxy S21 Ultra in top condition
Despite being a previous-generation model at this point, Samsung Galaxy S21 Ultra (opens in new tab) is still a top-of-the-line device that can go against the best Android phones out there, even if you choose to buy one today. However, a smartphone as premium and pricey as this also needs the best protection, so it's advisable to get one of the best Galaxy S21 Ultra. Our overall pick is Caseology's Nano Pop series, which comes with a dual-layer design and also features an impact-absorbent inner pattern for maximum protection against falls, scuffs, and scratches. Thanks to the two-tone colorways, you have a case that looks as great as it works.
Then there's Spigen Liquid Air P, which is a no-brainer if you plan on using an S Pen with your Galaxy S21 Ultra. With a convenient built-in compartment, it makes it easy to carry both the stylus and the smartphone together. On the other hand, if you tend to switch the cases quite often, we suggest going for Crave's Dual Guard series, as it has a whole bunch of vibrant color options to choose from.
While a case is great for protecting your smartphone's overall body, it often can't do much when it comes to the display. Therefore, we also suggest checking out some of the best Samsung Galaxy S21 Ultra screen protectors (opens in new tab) to keep that 6.8-inch Dynamic AMOLED panel looking great as ever.
