I know a lot of you want to go naked and show off the Galaxy S20 Ultra in all its 6.9-inch glory, but it's a half-pound, glass-backed phone that is super unwieldy, so you'll need at least a thin case. To paraphrase South Park, if you try to use the Ultra without a case, "you're gonna have a bad time." Never fear! Just because you need to use a case doesn't mean you need to bulk up your phone.
Tech21 Studio Colour
This ultra-thin case sports both 8-foot drop protection and anti-microbial properties while being made with plant-based materials. The color choices here are distinct and diverse, but I like the blue and cherry.
Totallee Thin
Totallee has been making wonderfully thin cases for years. If all you want is a little bit of grip and some scratch protection, it doesn't get any better than this 0.02-inch thick minimalist case.
Ringke Air-S
Ringke is better known for its clear cases, but the Air-S is a sleek TPU case that comes in four fun colors — and black, because every case has to come in black, I guess — and it offers the Ultra grip without big bulk or high prices.
Samsung Silicone Cover
Thin cases are perfect for big phones like the S20 Ultra. Samsung's Silicone Cover is a minimalist option that offers basic protection but, more importantly, makes the phone easier to grip. Available in You can get it in black, blue, navy, pink, white, or gray.
Anccer Ultra Thin
This hard plastic shell is available in six colors and offers some scratch protection and a lip around the camera module to keep your Ultra's Space Zoom camera lens from cracking or scratching.
Spigen Liquid Air
The flexible TPU on the Liquid Air makes it easier to get on and off of your new phone, and the deeper texture here makes it easier to keep ahold of your super-sized S20 Ultra. I just wish it came in other colors.
What are the best thin cases for the Galaxy S20 Ultra?
The S20 Ultra is a whole lot of phone to keep ahold of, and the glass back makes it even harder to securely hold in your hand. That's why a case is legitimately required for the Ultra, even if you're used to going naked with your phones. If you want the thinnest case possible with a little bit of grip and scratch protection, the Totallee Thin is a great option.
If you're willing to go a few microns thicker, though, you can add a feature most thin cases don't have: drop protection. The Tech21 Studio Colour claims that it can help your S20 Ultra survive drops up to 8 feet, and it comes in a half-dozen bright, cheerful colors. Well, five bright cheerful colors and black, but still, it's an excellent option for protecting your Ultra without adding bulk.
If you want more options for the Galaxy S20 Ultra (hey, we understand if you decide you want more case after all), there are plenty available.
