1. Samsung Silicone Cover
The Samsung Silicone Cover is a suitable phone case if you want to protect your Samsung without sacrificing style. It features a sleek silicone material with a soft texture that feels comfortable in your hands. The case is also fingerprint and smudge resistant, so your phone will maintain a clean look for a long time.
Besides its sleek design, this case adds extra functionality to your phone. It comes with Samsung’s S Pen, which is a handy tool for taking notes, editing photos, or sketching. It also has an S Pen holder on the left side of the case, enabling you to store your stylus safely when not in use.

The case is slim as it is only 0.52 inches thick, making wireless charging possible. It’s also compatible with Qi-charging for added convenience when you want to charge your phone with universal wireless mobile chargers.
If you are looking for a phone case with ruggedness and aesthetics in equal measure, consider the TORRAS. The Samsung Galaxy S21 Ultra case integrates four X-Shock corners and a certified MIL-STD-810H all-around protection against scratches, and bumps. It can also withstand 2,500 high-impact drops of up to six feet. Its tough polycarbonate back also makes your phone look stylish, thanks to its translucent matte black color.

Another standout feature of the TORRAS is the nano oleophobic casing that prevents annoying fingerprints and reduces smudges. This feature also boasts an anti-scratch surface, giving you a worry-free time carrying your phone.
The TORRAS is lightweight, thanks to its ultra-thin profile. Weighing only 1.13 ounces, the case adds negligible weight to your Samsung Galaxy S21 Ultra phone, enabling you to scroll comfortably for extended sessions.

3. Crave Slim Guard
The Crave Slim Guard is a great choice if you’re looking for a budget-friendly case that is simple yet reliable at protecting your Samsung Galaxy S21 Ultra against dents. Its hard TPU material at the back and soft rubber edges provide your phone protection from knocks. Additionally, this nine-foot drop-tested phone case is effective at absorbing shock in case of unavoidable drops on hard surfaces, helping maintain your phone’s new look for an extended time.
The precise cutouts make the case look like it is part of the smartphone itself, ensuring easy usage thanks to the tactile buttons that boast a distinct press.

5. Samsung LED Wallet Cover
Unlike most phone cases, the Samsung LED Wallet Cover protects both sides of your Samsung Galaxy S21 Ultra phone.

Youmaker’s in-built screen protector offers the versatility standards most phone cases don’t deliver. Besides protection, the front screen protector also works well with fingerprint ID, maintaining seamless sensitivity of the screen of your phone.
The case boasts convenience too, thanks to its built-in kickstand. The kickstand supports hands-free viewing, making it easy to handle other tasks while making a video call. Additionally, you may comfortably watch your favorite content in landscape mode by placing it on a flat surface.
7. Supcase Unicorn Beetle PRO
The rugged construction of the SUPCASE Unicorn Beetle Pro features unbending polycarbonate and multi-layered TPU, offering your Samsung Galaxy Ultra 21 phone dependable protection from drops as high as 20 feet. The bezels are also raised to ensure the screen and lenses don’t get scratches from direct contact with hard surfaces.

Q: Can I Use Samsung Galaxy S21 Cases for Samsung Galaxy S21 Ultra?
No. Although the Samsung Galaxy S21 and S21 Ultra look similar in appearance and features, the phone cases only fit the respective smartphones they are designed for.
This is because the Samsung Galaxy S21 is 6.2 inches, whereas the S21 Ultra is 6.8 inches. The size difference makes it impossible for the S21 cases to fit the S21 Ultra.
Q: Do Samsung Galaxy S21 Ultra Phone Cases Allow Wireless Charging?
Yes, most phone cases are compatible with wireless charging. However, thick or metallic cases may slow the charging speed. This may force you to take off the case before charging the phone.
Going for a phone case with a slim profile is advisable if you prefer fast wireless charging.
Q: Are Samsung Galaxy S21 Ultra Cases Repairable?
Since most phone cases’ damage may require quick fixes, repairing phone covers is possible, keeping in mind the durability of phone case materials. Plastic or silicone protects the phone from scratches for over five years.
Common issues like the accumulation of dirt and debris are solvable through regular cleaning. Often, the cost-effective solution for a broken phone case is buying a new one.
