There are a lot of ugly cases , but I'm quite fond of this green case from Griffin. It's really thin and has a bumper around the screen that feels fantastic, not to mention very sturdy. Griffin says the bumper should absorb and disperse shock, protecting the S20 from 10-foot drops. (I did not test this claim.) The back is transparent, and it comes in a fully clear case or in black.

I'm not going to lie, this two-layer case is pretty ugly. But what it lacks in style it makes up in utility. There's a kickstand on the back that feels a little sturdier compared to the one on the Spigen case above, and it props the S20 up in both landscape and portrait orientations.
The bumper is thick, and the top and bottom edges are decently raised for extra screen protection. The buttons are easily accessible as well, and you get a cover for the USB-C port. It's also dirt cheap.
I like these cases, but they didn't particularly stand out over the rest. They're still good buys.
Ringke Fusion for $10: These cases are simple but effective. They slot into the S20 phones perfectly and don't hamper button presses. The packaging is biodegradable, which is always nice, and the cases are extremely affordable. (S20, S20 Plus)
PureGear Slim Shell for $30: This case has metal button caps, adding a bit of class to an otherwise simple case. It's made with a mix of rubber and polycarbonate, and the top and bottom edges are slightly raised for some extra protection. I'm not a huge fan of the branding on the back, which sticks out. (S20, S20 Plus)
Speck Presidio Grip for $40: Speck, like other case makers in this list, claims its case offers 13-foot drop protection as well as antimicrobial protection. I'm not thrilled with its looks, but I liked this case more than Speck's other options because it's a good deal grippier. (S20, S20 Plus)
Gear4 Holborn for $45: The soft-touch back on this pricier option makes it feel nice, and it looks sleek in all black. The antimicrobial case is also quite slim, and it's wrapped in D3O, a polyurethane material that supposedly offers better shock absorption than regular plastic. (S20, S20 Plus)
There's only one case I really didn't like, and it's the LifeProof Next, which also costs a ridiculous $81. It was difficult to put on and painful to remove, and I had to exert a lot of force just to push the buttons. That being said, it does feel like it can live up to its claims of not letting in dirt, dust, snow, or debris. But the entire Galaxy S20 range is already IP68 dust- and water-resistant, so unless you're trekking in extreme environments, this bulky case is overkill.
