Samsung’s new Galaxy S21 Ultra is the Galaxy’s most powerful flagship yet. It comes with improved cameras, S Pen compatibility, and a stunning 6.8-inch display. However, if you are the type of person who is prone to dropping your phone, you may still require a suitable case to provide additional protection from scratches. Thanks to the brand, which has over a hundred case options on the market, you can find the best one for your needs. But, since you’re here, we’ll make it easier for you by compiling a list of the 10 Best Phone Cases for S21 Ultra, which you can read about below. Don’t worry; each of the cases included is well worth contemplating, as well as the money spent on them.

Frequently Asked Questions (FAQs)

In case you don't know...

Which type of case is better for mobile?

Choose a case made of a shock-absorbent material (like silicone or rubber) that covers your phone's susceptible corners for a basic level of protection. However, if you are more concerned with the case's design, plastic is acceptable; however, you should be aware that it does not adequately absorb shock, so make sure you are not prone to dropping your phone.

Does phone case really protect phones?

A case that covers the corners, edges, and back of a smartphone is your best chance for overall device protection. When your phone is dropped, a good case will protect it from scratches and absorb impact in certain places.

Are soft phone cases better than hard?

Because they absorb shock, soft rubberized cases provide better protection than hard cases. Hard cases will only protect your phone from dents and scratches, but not from a powerful shock. The only disadvantage of soft casings is that they degrade with time. But it all depends on your preferences; each variety has its own set of advantages and disadvantages.

Can a phone case affect WIFI?

Any phone case can cause signal loss if the design or material of the case interferes with the cell phone antenna in any way. The majority of today's case materials will not absorb or obstruct any significant quantity of Wifi or cellular signal, but some will.

Samsung
Galaxy S21 Ultra 5G S-View Cover with S-Pen

Excellent Phone Case

price from
$89.99
Our Opinion:

This is the other alternative for a case with an S Pen silo. For the past five years or so, the Samsung S-View Cover with S Pen has been a popular case. It primarily serves as a cover for the phone's front, but it also has a window on the right side that displays the date, time, weather, and certain notifications.

Promising Review:

i am loving the design and fit of this case and the s-pen is awesome! the case utilizes some of the best features of the phone while keeping it safe and looking stylish. i absolutely love this case!

ESR
Metal Kickstand Case

Hands-Free Phone Case

price from
$15.99
Our Opinion:

If you want to watch your shows hands-free on your gorgeous Samsung S21, this ESR cover is a good option. It has a sturdy metal kickstand that can be used vertically or horizontally, and the clear finish shows off your phone's design. If you want to disguise your phone, a black variant is also available.

Promising Review:

This is my first kickstand case and my first from ESR. Great first impression. Case fits great. All ports and speakers are cutout great. Thin but feels protective. Have the black version and it has a nice matte finish. Grippy and fingerprint free. Kickstand is very sturdy. Does everything as advertised.

Optimal Impact Protection Case

price from

Our Opinion:

It has a MIL-STD 810G grade and is built with Hyper Cush technology for optimal impact protection. Eggplant, Mallard, and Olive are just a few of the subtle colors available. A faint orange highlight appears on the front of each option, and a honeycomb design protects the inside of the casing.

Promising Review:

Love this case. Does everything and more. 100% satisfaction. Its durable, sleek, and can be set up for a magnetic car holder. Must have addition.

Caseology
Nano Pop Case

Case with Air Space Technology

price from
$15.99
Our Opinion:

The Caseology Nano Pop is a relatively new addition to our case lineup, but it's a great alternative for thin protection. It's a matte case that comes in two colors: gray and navy blue. The term Nano Pop refers to the little ring of color that surrounds the camera unit, and the navy blue version has a raised yellow lip. In either case, your Galaxy S21 Ultra will be protected by Air Space technology on all four corners.

Promising Review:

This is such an awesome case. Soft to touch, like soft plastic, silicone-ish. Looks premium too. Colors looks great and combination is interesting. ...

Parallax

Case with Stunning Rear Pattern

price from
$24.99
Our Opinion:

The Caseology Parallax has raised edges to keep your phone's screen off the ground when you set it down, as well as a detachable plastic bumper to protect your phone from large drops. All of this is accomplished while adding only 0.16 inches to the handset, allowing you to keep your large phone as tiny as possible. What's more, the stunning rear pattern is what sets it apart, thanks to the textured grip, which makes it easier to grasp.

Our Opinion:

Otterbox's tried-and-true Commuter line completes our list of the finest Galaxy S21 Ultra cases. This cover helps protect your phone from minor bumps and drops. It also has Otterbox's antibacterial technology, which helps prevent bacteria from growing on your phone case.

Promising Review:

I just got this case like 5 days ago for my new S21 Ultra and it's perfect.. I had my last Galaxy phone for almost 5 years with the same Otterbox case and it survived 100+ drops at least. Highly recommend this brand.

Presidio2 Grip Samsung Galaxy S21 Ultra 5G Case

Superb Grip Case

price from
$19.99
Our Opinion:

This case, as the name suggests, provides a superb grip to prevent your phone from dropping out of your hands. If your Galaxy S21 Ultra falls on the ground, the Presidio2 Grip's Armor Cloud technology will protect it. As a result, air cushions will work hard to absorb the majority of the impact shock. It also possesses antibacterial defense, which helps it defend against the great majority of diseases.

Promising Review:

I have had this on my S21 Ultra and have dropped it a few times from about 4 feet high and the phone still functions perfectly; screen still in one piece - no radial cracks, not a scratch. I have dropped the phone on one corner, on one side, it hit the cement sidewalk and bounced once while on a late night bicycle ride; DAMN THING IS AWESOME!

Antibacterial Grip Case

price from

Our Opinion:

This Grip case from Incipio is designed to give you the finest grip possible. The multi-directional grip will help avoid unintentional drops by making it simpler to keep hold of your Galaxy S21 Ultra. The Grip also has antibacterial and shock-absorbent technologies incorporated right into the casing.

Promising Review:

This is by far the best case I have used for the S21 Ultra. I have bought 6 cases already and I'm going to throw them all away and keep this one. Excellent grip. Antimicrobial. Feels good in hand.

Spigen
Rugged Armor Designed Case

Case with Shinny Accents

price from
$13.99
Our Opinion:

For Galaxy S21 Ultra owners, the Rugged Armor case is an option. This case is made from a flexible TPU material, which some people prefer to the hard polycarbonate shells. The Rugged Armor offers some good style to capture the eye and protects the Galaxy S21 Ultra from scratches and bumps, but this is a matter of personal preference. It has carbon fiber highlights and shiny accents to make it stand out.

Promising Review:

Always buy these cases when I get a phone. This one didn't disappoint either. Would recommend to anyone interested in a budget rugged style case.

Spigen
Tough Armor Designed Case

Durable Tough Case

price from
$17.99
Our Opinion:

This is for those who want the highest protection Spigen has to offer and the peace of mind that comes with it in the case of a phone drop or bump. This S21 Ultra case is extremely tough and long-lasting. It's made of shock-absorbing impact foam and has a low profile to keep you from feeling like you're holding a brick. Not only that, but it also provides superb side-to-side grip.

Promising Review:

I've used this line of cases for other Samsung phones and they have held up well and saved me from a few drops. This one fits well and the rubber lip at the bottom prevents accidental home/back screen key presses when using the phone with one hands. I generally hold it resting on my pinkie and using my thumb to do everything, and without the case every time I would reach for something up high my finger would hit a bottom screen button. Now, with the case, I don't.
