Direct answer: all three of these legacy Samsung flagship cases are built on aluminum alloy 6061 and rated to 12 ft / 3.6 m, but the Galaxy S22 Ultra Aluminum Metal Case with Kickstand is the best all-around pick because it adds a built-in stand. The Galaxy S20 Ultra Military Metal Case is the most heavily armored, and the Galaxy S21 Plus Heavy-Duty Aluminum Case is the slimmest in a pocket.
Gorilla Family, these three Samsung flagships are still in daily service across job sites, fleets, and family hand-me-downs. The Galaxy S20 Ultra, Galaxy S21 Plus, and Galaxy S22 Ultra all share one thing: enormous, expensive glass panels on both sides. This comparison puts our three aluminum armor builds head to head so you can pick by body size, weight, and features rather than guessing.
Why legacy Samsung flagship protection matters in 2026
Samsung Ultra bodies are tall, wide, and heavy. That geometry means a drop rotates the phone, and rotation puts corners and edges into the impact path first. Corner-first landings are the single most common way a Galaxy display dies.
Legacy Samsung glass is also getting expensive to replace relative to the phone value. A back panel swap on a Galaxy S20 Ultra involves heat, adhesive, and a camera island that does not like being disturbed. Prevention is far cheaper than repair on these models.
Then there is the camera island itself. All three of these phones carry a proud camera bump, which is why every case in this comparison uses a raised 1.2 mm machined lip around the lenses.

The interesting result here is that protection is nearly identical across all three. Every one of these is aluminum alloy 6061 over a TPU plus polycarbonate liner, tested to MIL-STD-810G and rated 12 ft / 3.6 m. What actually separates them is features and bulk.
Ten key features across these three Samsung metal cases
- Aluminum alloy 6061 frames, CNC machined and anodized so the finish does not flake at the corners.
- 12 ft / 3.6 m drop rating across all three, verified on corner, edge, and face impacts.
- MIL-STD-810G testing covering shock, vibration, and temperature extremes.
- TPU plus polycarbonate inner liner that isolates the phone body from the metal frame.
- Raised 1.2 mm machined camera lip so the Samsung camera island never contacts a flat surface.
- TPU antenna breaks engineered into every frame so an aluminum shell does not choke cellular signal.
- Integrated metal kickstand unique to the Galaxy S22 Ultra case, strong enough for landscape video.
- Tempered glass front panel on most Galaxy S20 Ultra military metal finishes for full front-to-back coverage.
- Machined button caps that keep a positive click feel through a rigid metal frame.
- 15 W magnetic wireless charging on open-back finishes, so you keep the convenience where the design allows it.
Gorilla Cases offers metal armor for Samsung generations most retailers abandoned years ago, including full holster and belt clip variants. That is the practical reason these three exist in one catalog.
Who each Samsung case is for
The Galaxy S20 Ultra military metal case is for total coverage. If your phone gets buried in a tool bag, dropped onto gravel, or set face down on a workbench, the full-body build with a tempered glass front is the one to buy.
The Galaxy S21 Plus heavy-duty aluminum case is for the reader who wants real armor without a brick in the pocket. The S21 Plus is the smallest body here, and the bumper-style aluminum build keeps it manageable.
The Galaxy S22 Ultra aluminum metal case with kickstand is for people who use the phone hands-free. Navigation on a dash, video on a lunch table, or a video call on a desk.

An illustrative use scenario
Here is an illustrative example, not a verified customer review. Picture a small HVAC company in Ohio running a mixed fleet of older Samsung flagships. The install lead carries a Galaxy S20 Ultra in the full military metal case, because his phone goes into crawl spaces and attics and comes back out covered in insulation.
The service tech carries a Galaxy S21 Plus in the slim aluminum bumper. He is in and out of a van forty times a day and hates pocket bulk, so the 12 ft / 3.6 m rating in the thinnest possible aluminum body is the right trade.
The estimator carries a Galaxy S22 Ultra in the kickstand case. She props the phone on a truck dash for turn-by-turn directions and on a kitchen counter to walk homeowners through quotes. The stand is the feature she actually uses.
Eight protection tips for Samsung metal cases
- Tighten frame screws in a cross pattern, a quarter turn at a time, so the frame never pinches the glass.
- Add tempered glass to any open-front metal case. Aluminum protects the frame, not the display.
- Rinse and dry a metal case after salt or chemical exposure. Anodizing resists corrosion but does not prevent it.
- Clean the raised 1.2 mm camera lip weekly. Grit trapped in a machined lip acts like sandpaper.
- Do not force a wireless charger through a solid metal back. Use an open-back finish if you want 15 W magnetic wireless charging.
- Replace the TPU liner if it goes hard or shiny. A compressed liner no longer absorbs shock.
- Keep the S22 Ultra kickstand folded when the phone is in a bag so the hinge does not get levered open.
- Remember that none of these are sealed. For water, buy an IP68 case rated 1.5 m for 30 minutes.
What is in the box and how to install
Each of these ships as a machined aluminum frame, a TPU plus polycarbonate liner, a hex driver, spare screws, and a microfiber wipe. The Galaxy S20 Ultra military metal case adds a tempered glass front panel on most finishes. The Galaxy S22 Ultra case ships with the kickstand already riveted to the frame.
- Power the phone down and clean the front, back, and camera glass.
- Seat the phone into the TPU liner first, pressing the camera island cutout into place before the corners.
- Align both aluminum frame halves around the liner and start every screw by hand before tightening any of them.
- Tighten in a cross pattern, a quarter turn per screw, until the frame is flush and even.
- Test all buttons, the fingerprint sensor, the speakers, and the camera.
- On the S22 Ultra case, open and close the kickstand a few times to confirm the detent holds.
