The best Galaxy S20 vs Galaxy S20 Plus vs Galaxy S20 Ultra case choice in 2026 comes down to screen size: the 6.2-inch S20 fits the Galaxy S20 Metal Military Grade Heavy Duty Case, the 6.7-inch S20 Plus fits the Galaxy S20 Plus Aluminum Gorilla Case, and the 6.9-inch S20 Ultra fits the Galaxy S20 Ultra Military Metal Case. Each one is a Gorilla Cases build with real metal or IP68 sealing rather than a thin shell.
Gorilla Cases offers a matching waterproof option for every size too. This 3-way Samsung case comparison walks through what each Galaxy S20 case does, what it costs, and which one deserves a spot on your phone.
Why this case matters in 2026
The Galaxy S20 family is from 2020, which means most of these phones are now on their second or third owner and have already taken a few drops. A good Galaxy S20 case in 2026 is not about looks. It is about keeping a phone that still works well out of the repair shop.
The three sizes behave very differently in the hand. The 6.2-inch Galaxy S20 slides into a pocket, the 6.7-inch Galaxy S20 Plus is a two-handed phone for many people, and the 6.9-inch Galaxy S20 Ultra is the largest and the easiest to drop from a bag or a truck seat.
Galaxy S20 owners also tend to keep these phones as backup devices, work phones, or hand-me-downs for kids. That is a good reason to buy the sturdier Galaxy S20 case now rather than replace a cracked screen later.
Case type matters as much as case size. Gorilla Cases offers screw-together aluminum armor for job sites and sealed IP68 enclosures for water, and the product descriptions are clear about which is which. We keep that honesty here: the metal cases are weather-resistant, not submersion-rated.

Illustrative use scenario
Imagine three coworkers on the same site, one with a Galaxy S20, one with a Galaxy S20 Plus, and one with a Galaxy S20 Ultra. This is an illustrative example, not a customer testimonial.
The S20 owner clips on the metal case and forgets about it. The S20 Plus owner props the phone on a toolbox using the kickstand. The S20 Ultra owner takes the waterproof version for a rainy week of concrete pours and wipes it clean at lunch.
Protection tips
- Match the case to the exact phone: S20, S20 Plus, and S20 Ultra cases are not interchangeable.
- Tighten metal case screws gently and check them monthly, since vibration can loosen them.
- Use the included screwdriver and spare screws on the S20 Ultra Military Metal Case rather than improvising.
- Close every flap and plug on a waterproof case before any water contact, then rinse with fresh water after salt or chlorine.
- Re-register your fingerprint after installing the waterproof Galaxy S20 Plus case, as the product page recommends.
- Do not treat the aluminum cases as dive cases. They resist rain and splashes but are not submersion-rated.
- Wipe the screen protector and the case interior before installing so dust does not trap under the glass.
What's in the box and how to install it
Each Gorilla Cases listing ships the case for your selected model and color, and the S20 Ultra Military Metal Case includes a screwdriver and spare screws. Check the product page for the exact contents of the variant you choose.
For the metal cases, lay the phone into the lining and set the frame, then tighten the side screws evenly. For the waterproof cases, snap the two halves together around the clean, dry phone until the seal closes.

Final verdict
Choose by screen size first, then by case type. The S20 gets the metal heavy-duty case or the shallow-rated waterproof case, the S20 Plus gets the kickstand aluminum case or the fingerprint-friendly waterproof case, and the S20 Ultra gets the military metal case or the 30-minute IP68 waterproof case.
A practical rule: if your phone mostly lives on a desk or in a car, a metal case is overkill and a sealed case is the smarter spend. If it lives in a tool bag, the screw-fixed aluminum frames are the better fit.
