The best Samsung Galaxy S20 thin cases:

Spigen Thin Fit

The Spigen Thin Fit isn’t the most protective case on this list but is ideal for those who don’t want to add any bulk to the phone. Precise cutouts are available for easy access to all ports, buttons, and features. Covered corners help with drop protection, and a slightly raised lip keeps the display and rear camera safe.

Poetic Karbon Shield

The Karbon Shield is a light and flexible TPU case from Poetic that’s form-fitted to maintain a slim profile. A patterned back and sides with anti-slip finishes help to improve grip. It has a slightly raised lip for screen protection without adding too much bulk to the overall weight. Poetic’s Karbon Shield is screen protector-friendly, so you can add even more protection.

Caseology Parallax

Caseology Parallax for Samsung Galaxy S20 Case

The Caseology Parallax features a dual-layer design that combines TPU and polycarbonate materials into a slim cover that barely adds any bulk to the phone. The geometric design on the back adds a touch of style, and the textured finish helps with the grip. You get covered buttons, precise cutouts for everything else, and a raised lip around the display and rear camera setup.

Speck Presidio Grip

The Speck Presidio Grip combines a polycarbonate outer shell and an impact-absorbing inner material to keep the phone safe. Angled rubber ridges on the back add to the grip and stop the phone from sliding off surfaces. Raised bezels around the screen, covered buttons, reinforced corners, and Microban antimicrobial technology (that reduces bacteria by 99%) add to the protective capabilities of the case.

PHNX thin case

PHNX Galaxy S20 mnml case

If you want a super thin Galaxy S20 case, the PHNX thin case is as thin as it gets. The .35mm body adds virtually no weight or bulk to the phone, although it also won’t add much protection. It’s also, as the name implies, very minimal, with no visible branding on the exterior of the case. It comes in matte black as well as two translucent colors: frosted black and frosted white.

UAG Plasma

UAG Samsung Galaxy S20 Case

The UAG Plasma is a feather-light case for the Samsung Galaxy S20 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 wireless charging, Samsung’s Powershare, and mobile payments.

Spigen Rugged Armor

Spigen Rugged Armor

The Spigen Rugged Armor is one of the best Galaxy S20 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 and camera safe, and you also get covered buttons.

ESR metal kickstand case

ESR Metal Kickstand

If you’re looking for a case that isn’t bulky but still offers the convenience of a built-in kickstand, this ESR case is for you. The flexible TPU case comes with a raised lip and reinforced corners. The metal kickstand is sturdy and lets you prop up the phone in both landscape and portrait orientations, and also allows you to change the viewing angle.

Encased Duraclip w/ holster

Encased Bolt Clip

Belt clip holsters are usually available with rugged cases. If you’re looking for this convenient accessory but with a thin case, 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.

Moment Galaxy thin case

Moment Thin Case

The Moment Galaxy S20 thin case is perfect for the environmentally conscious Samsung user. Not only does it feature a super-thin 1.5mm body and soft-to-the-touch texture, but it’s also 100% compostable. When you’re done with it, you can throw it in your compost, and it will biodegrade, rather than going to a landfill. This eco-friendly aspect doesn’t take anything away from its protective merits, with it passing the six-foot drop test at all angles.
