The short answer: these three Samsung Ultras need different cases for structural reasons, not just sizing. For the Galaxy S20 Ultra, choose the Galaxy S20 Ultra Military Metal Case because impact is the main risk on a six-year-old phone. For the S21 Ultra, choose a sealed IP68 waterproof shell. For the S22 Ultra, choose a metal or kickstand case that clears the built-in S Pen silo, which the S22 Ultra introduced and the other two lack.

Why These Three Ultras Need Different Cases in 2026
The S22 Ultra is the dividing line. Samsung merged the Note line into the Ultra with the S22 generation, adding a built-in S Pen silo that neither the S20 Ultra nor the S21 Ultra has. Any case for an S22 Ultra must leave that silo unobstructed.
Body shape changed too. The S20 Ultra and S21 Ultra have curved rails, while the S22 Ultra moved to a more squared profile with sharper corners. A case molded for a curved body will not seat properly on the squared one.
Camera modules differ dramatically. The S20 Ultra has a large rectangular module, the S21 Ultra wraps its module into the frame in a contour bump, and the S22 Ultra uses individual raised lens rings with no housing. A case lip designed for one sits directly on the lens glass of another.
Galaxy S20 Ultra Cases: Impact Prevention on a Legacy Flagship
An S20 Ultra in 2026 is a six-year-old phone, typically serving as a secondary or hand-me-down device. Display assemblies are increasingly scarce and the labor cost has not dropped, which makes any repair uneconomic. Prevention is the only sensible strategy.
A metal case is the strongest answer. The Galaxy S20 Ultra Military Metal Case uses a full-body aluminum frame and carries a MIL-STD-810G rating.

Galaxy S21 Ultra Cases: Restore the Water Seal
The S21 Ultra shipped IP68 rated, and by 2026 those adhesive seals should be considered expired. Samsung excludes liquid damage from the standard warranty, so a water event on this phone is a total loss. A sealed case restores protection the phone no longer has on its own.
The S21 Ultra also supports the S Pen, but without a silo to store it. That means owners either carry the pen loose or choose a case with a pen loop, which is a genuine difference from the S22 Ultra.
The Galaxy S21 Ultra Waterproof Case is the reference option here.
Galaxy S22 Ultra Cases: S Pen Silo Clearance Is Mandatory
The S22 Ultra was the first Ultra with a built-in S Pen silo, and a case that blocks or partially covers it makes the phone's headline feature unusable. Silo clearance is not optional on this model.
The individual raised lens rings also change the case requirement. Without a unified camera housing, the case has to provide its own raised surround, or the lens glass contacts every surface the phone is set on. A metal case with a machined surround handles this well.

An Illustrative Scenario: Managing a Mixed Fleet
What follows is an illustrative example rather than a verified customer account. Picture a landscaping company with three Samsung Ultras still in service across the crew, bought in different years as phones were replaced one at a time.
The S20 Ultra rides in a truck and takes concrete drops, so metal is the answer. The S21 Ultra belongs to an irrigation tech who works in standing water, so IP68 sealing is what matters there. The S22 Ultra belongs to the estimator who marks up site plans with the S Pen, so silo clearance is non-negotiable.
Three phones with nearly identical screen sizes and three completely different correct cases. Buying by model name alone is how fleets end up with cases that block the pen or sit on the lenses.
Which Case Type Should You Buy
- Choose metal when repair cost exceeds the phone's used value and drops are the risk.
- Choose waterproof when factory seals have aged out and the phone goes near water.
- Choose kickstand when you watch video or take calls with the phone propped.
- Choose wallet when the phone has become a utility device and carry consolidation matters.
- Choose clear when resale condition is still worth protecting.
- Choose rugged with a holster when you work standing up all day.
Twelve Frequently Asked Questions
1. Which of these has a built-in S Pen slot? Only the Galaxy S22 Ultra. The S20 Ultra has no S Pen support at all, and the S21 Ultra supports the pen without a silo.
2. Will an S21 Ultra case fit an S22 Ultra? No. The S22 Ultra has squared rails and a completely different camera layout.
3. Will an S20 Ultra case fit an S21 Ultra? No. The camera modules are entirely different shapes.
4. Are these phones still water resistant? Their factory seals degrade with age. Treat any phone this old as not water resistant.
5. Do metal cases block Samsung signal? Not when they use dielectric breaks at the antenna bands, as ours do.
6. Do any of these support wireless charging through metal? Yes, when the case has a non-ferrous charging window, though speeds may be slightly reduced.
7. Which Ultra holds the most resale value? The S22 Ultra of these three, largely because of the integrated S Pen.
8. Does the ultrasonic fingerprint sensor work through sealed cases? It can be unreliable through a sealed membrane. Set up a PIN or face unlock as a backup.
9. Which case type is thinnest? Clear bumpers, though metal is the best protection-to-thickness ratio.
10. Can I use a case with an S Pen loop on the S22 Ultra? You can, but the phone already stores the pen internally, so it is redundant.
11. What is the return policy? A 30-day exchange policy on every case Gorilla Cases ships.
12. Is there a discount code? Yes, code 10OFF for 10 percent off.

Final Verdict on the Galaxy S20 Ultra vs S21 Ultra vs S22 Ultra Case Comparison
These three phones share a name and a screen size and almost nothing else that matters for cases. The S20 Ultra is a prevention case where metal wins, the S21 Ultra is a restore-the-seal case where IP68 wins, and the S22 Ultra is an S Pen case where silo clearance is the requirement. Camera geometry rules out any cross-fitment.
