Now is looking like a great time to buy Samsung’s 2021 flagship, so let’s find the best Samsung S21 Ultra case to go with it.
Two years since its release, the Samsung S21 Ultra remains a powerhouse. It excels in cameras, display and overall performance, meaning choosing the right case is an important decision if you want your phone to last. That being said, it might be worth considering the Samsung Galaxy S23 due to come out in fairly soon – it all depends on the trade-off between price and new features.
We’ve selected the best phone cases based on the level of protection offered, style and case type. There’s no shortage of designs that prioritise different features. Perhaps you’re after a protective case for peace of mind, but don’t want to lose out on aesthetics, in which case you should go for Mous’ Limitless 3.0. Or, if you like to watch videos and make video calls, two of our selections have a built in stand that should come in handy.
While the Samsung S21 Ultra may be slightly too premium to be considered one of the best mid-range phones, it may come close to some of the best gaming phones.
Regardless of what you’re after, we should have something that suits you – so let’s get stuck in, here are the best Samsung S21 Ultra cases.

- Mous Limitless 3.0 case
- ESR Metal Kickstand case
- Samsung Official LED View Flip Cover case
Best overall Samsung S21 Ultra case – Zagg Gear 4 Crystal Palace
Zagg Gear 4 Crystal Palace
The Zagg Gear 4 Crystal Palace takes the number one spot thanks to its protective, sleek & simple design.
Its standout feature has to be D3O Crystalex, a soft and flexible material boasting to be the most transparent protective material for phone cases. The D3O material hardens on impact from up to 13 feet, dissipating shock and protecting your device.
Unlike poorly made clear phone cases that look good when they’re new, but yellow over time, the Zagg Gear 4 Crystal Palace is resistant to dye transfer. This means your case will retain its beautiful transparent finish, showing off the sleek and attractive colours of your Samsung S21 Ultra. This is a massive win when it comes to phone cases – at the end of the day, all you want is your phone to look good and avoid cracks and scratches.
This is particularly true if you’re using it out and about a lot for example if you’re gaming on it often. Also worth noting is that if you’re a phone gamer you might want to check out our dedicated page to finding the best gaming phone to help you find the best device for your needs.
One other notable feature is that it’s compatible with wireless charging so you can get the most out of your Samsung S21 Ultra.
Otterbox Defender
With the Otterbox Defender case, expect peace of mind from serious drops, scrapes and dirt plus a handy versatility feature (hint: it has a holster).
The Otterbox Defender does not mess around with protection. It has a multi-layer defence with a solid inner shell and resilient outer slipcover. It doesn’t stop there, with port covers to prevent dust, dirt and lint from clogging your Samsung’s ports and jacks. With protection like this, the Otterbox Defender is a great choice if you’re committed to making your phone last.
It’s a brilliant choice for the adventurers amongst us. Not only will its port covers protect your phone from different terrains like sand or dirt, but its handy holster can function as a belt clip meaning you’re not limited to pockets when it comes to travelling with your phone. We’ve actually previously chosen the Otterbox Defender series as the best protective case option when we were looking into the best Google Pixel 7 Pro case – so this is a bit of a favourite recommendation of ours.
We also love that the holster can also function as a stand, so if you regularly watch longer videos on your phone, you’ll find this phone case super convenient.
Best protective Samsung S21 Ultra case – Mous Limitless 3.0
Mous Limitless 3.0
We’re seriously impressed by Mous’ Limitless 3.0 case which provides incredible protection without succumbing to the usual bulky aesthetic of a protective case.
Its high quality protection is down to the company’s very own AiroShock technology, meaning the case disperses the energy that comes from drops that would otherwise go into your phone. If you’re serious about protection, it’s always worth investing in a screen protector. However, it’s worth mentioning that Mous has crafted edges that are bigger in the corners than on the long edges, meaning it provides very good protection for the front of your phone case as well as the back without adding bulk to the case’s slim design.
Though in the higher price bracket, the Mous Clarity Lite is the sweet spot for users after high-grade protection without compromising the attractive design of their Samsung S21 Ultra. We had the same balancing act to contend with when we were looking into the best Google Pixel 6 case.
Best Samsung S21 Ultra case with stand – ESR metal kickstand case
ESR metal kickstand case
There’s a lot to like about the ESR metal kickstand case, which allows you to prop the phone up in both landscape and portrait mode.
Measuring 6.2 inches, the Samsung S21 Ultra is a large phone that needs a sturdy stand to support it. The ESR metal kickstand case seriously rises to the job, providing comfortable viewing at multiple angles. This makes it a great choice if you’re making lots of video calls or else watching videos – and why wouldn’t you with a battery life lasting up to 10 hours?
It’s also conveniently compatible with wireless charging and offers pretty good protection thanks to its Air-Guard corners.
Overall, the ESR metal kickstand case brilliantly compliments the Samsung S21 Ultra and is a sound choice if you regularly stream content on your phone.
Best Samsung S21 ultra case with card holder – Samsung Official LED View Flip Cover case
Samsung Official LED View Flip Cover case
You definitely get a nice peace of mind when you’re buying your S21 Ultra that’s made by Samsung.
This wallet-style folio case allows room for a bank or travel card in the interior pocket, meaning you can keep what’s important safe with your phone. Going one step further than a traditional wallet, this case lights up the front of your phone with LED icons designed to deliver notifications without needing to open the cover.
Thanks to the flip design, expect all round protection meaning your phone will be protected from most bumps and knocks. This means there’s also potentially less of a need for a screen protector, though if you’re prone to dropping your phone, we’d say get one anyway for peace of mind.
Though some may need more space in their phone case for a single card, we think the LED View Flip Cover case covers your bases with what’s most important.
