Spigen Ultra Hybrid

Samsung Galaxy S20 Ultra Spigen Ultra Hybrid case

Spigen is a perennial favorite of ours at Android Authority, and this clear Galaxy S20 Ultra case is a safe choice for just about anybody. The Ultra Hybrid comes with a rigid polycarbonate back and a soft TPU bumper to provide excellent protection for the Galaxy S20 Ultra. A raised lip keeps the display and rear camera safe, and the buttons are covered as well. The case utilizes Air Cushion technology to ensure the phone survives any accidental drops.

Poetic Karbon Shield

Poetic Karbon Shield case for Samsung Galaxy S20 Ultra

The Poetic Karbon Shield is a slim, form-fitting TPU case with carbon fiber elements that add a touch of style and enhance grip. You get a raised lip to keep the rear camera and the display safe, but it still works with screen protectors. Covered buttons and precise cutouts for easy access to everything else are also available.

If you want something with more protection and don’t mind the bulk, the Poetic Spartan is an excellent rugged option as well. It features military-grade protection, a built-in kickstand, and an ultra-resistant frame that’s fitting for one of the best Galaxy S20 cases you can buy.

Spigen Rugged Armor

Spigen Rugged Armor case for Samsung Galaxy S20 Ultra

We know we’ve mentioned Spigen already, but we can’t leave off the Spigen Rugged Armor because it’s easily one of the best Samsung Galaxy S20 Ultra cases you can buy. It offers excellent protection without adding too much bulk or thickness by utilizing air cushion technology and a spider-web pattern inside for shock dispersion. A raised lip keeps the display, camera, and fingerprint scanner safe, and you also get covered buttons. The only downside is that it only comes in black.

UAG Plasma

UAG case for Samsung Galaxy S20 Ultra

The UAG Plasma is a feather-light (but still rugged) case for the Galaxy S20 Ultra that combines a hard outer shell and an impact-resistant core. A raised rubber lip and reinforced corners add to the protection as well. The case meets MIL-STD 810G-516.6 drop-test standards but is thin enough to let you use mobile payments.

PHNX mnml case

PHNX Galaxy S20 ultra mnml case

If you don’t need that much protection and want something thin, the mnml case is the thinnest there is. Clocking in at just .35mm thin, it’s super light and adds virtually no bulk to your device. It also doesn’t add to much in the way of protection, but it does at least have a raised lip around the camera bump. It comes in matte black, frosted black, and frosted white.

Ringke Fusion-X

Ringke Fusion X case for Samsung Galaxy S20 Ultra

The Ringke Fusion-X comes with a dual-layer design that offers a lot of protection. Like the option above, the hard polycarbonate back is transparent and lets you show off the color and design of the phone. A raised lip keeps the display and the rear camera safe, while the sides and corners are reinforced with a TPU bumper for added drop protection. One thing that makes this case unique is that it features a built-in lanyard hole to connect wrist and neck straps.

FYY genuine leather wallet

FYY case for Samsung Galaxy S20 Ultra

The FYY Samsung Galaxy S20 wallet case is made with genuine leather that looks and feels great. A magnetic clasp holds the folio cover in place, and the latter can also be folded into a kickstand. It comes with three slots for bank cards or ID and a large cash pocket.

Encased Duraclip

Encased Belt Clip Case for Samsung Galaxy S20 Ultra

Belt clip holsters are usually available with rugged cases. If you’re looking for this convenient accessory with a thin case, though, the Encased Duraclip is for you. It has a patterned back and rubberized finish that adds to the grip. The holster holds the phone securely in place, and you can rotate it. The case also comes with a built-in kickstand that lets you prop the phone up in both orientations.

Otterbox Defender

Otterbox Defender case for Samsung Galaxy S20 Ultra

Otterbox is the go-to brand for rugged cases, and the Defender series provides the most protection. It’s thick and bulky, with covered buttons and ports, and has a raised lip to keep the display safe. The Otterbox Defender also comes with a belt clip holster. This rugged case is expensive and will be overkill for some. If complete protection is what you want, though, that’s exactly what you get.
