For the standard Samsung Galaxy S21, the clearest sourced choices are Samsung’s Clear Protective Cover, Samsung’s Protective Standing Cover and OtterBox’s Symmetry Series. Pick by the feature you need—transparent finish and stated grip, a built-in viewing stand, or a slim profile with raised edges—and confirm the listing says Galaxy S21 or Galaxy S21 5G. Manufacturer drop-test claims are not independent proof that one case protects better than another.
Which Galaxy S21 cases are worth comparing?
These are three manufacturer-listed cases specifically identified for the standard Galaxy S21 family. They are not recommendations for the Galaxy S21+, S21 Ultra or S21 FE; those are different models, so verify the exact device name on the case listing.

Samsung’s listed dimensions and weights are case specifications, not measures of impact protection. OtterBox also lists dimensions and weight, but cross-brand measurements may use different conventions, so they are not necessarily directly comparable.

Choose by the feature you need
For a clear case with a stated grip feature
Samsung’s Clear Protective Cover keeps the back transparent and has a non-slip border pattern, according to Samsung. It is the lightest of the two Samsung cases in the cited specifications at 33 g. That makes it a straightforward choice if you want the phone’s finish visible without adding the standing cover’s kickstand feature.

For a Galaxy S21 case with a kickstand
The Samsung Protective Standing Cover has built-in kickstands for viewing at 45° or 60°. Choose it if those two angles suit how you watch or read; the cited product page does not describe additional stand positions. Its listed weight is 49 g.
For a slim case with raised edges
OtterBox describes Symmetry as having a slim profile and raised edges intended to protect the camera and touchscreen. OtterBox suggests pairing the case with a screen protector, but the cited page does not establish a particular protector’s fit or compatibility with every case.
Rank #2
- Compatible with Samsung Galaxy S21 5G (Not Compatible with Plus, FE, Ultra models)
- Thin, pocket-friendly case slips in and out of pockets easily. Secure grip for confident handling
- Port covers block dirt, dust and lint from getting into jacks and ports. Raised edges protect camera and screen
- Drop+ 3x as many drops as military standard (Mil-Std-810g 516.6). Wireless charging compatible
- Includes OtterBox limited lifetime warranty (see website for details)
What the drop-test claims do—and do not—show
Samsung says the Clear Protective Cover was tested to MIL-STD-810G Transit Drop standards for drops from 1.5 metres onto a steel surface, at temperatures between 15°C and 35°C and 0–80% relative humidity. Samsung adds that the standard follows accredited test results and that performance may vary with actual use and other factors. This is a manufacturer-reported test condition, not a guarantee against damage in a particular fall.
Samsung gives the Protective Standing Cover the same stated 1.5-metre steel-surface drop condition. OtterBox states, “DROP+ | 3X as many drops as military standard (MIL-STD-810G 516.6).” That is OtterBox’s own claim. The cited pages do not provide an independent, common-protocol comparison between these cases, so the claims cannot establish which one performs best in real-world use.

Check before buying
- Confirm that the case listing names the standard Galaxy S21 or Galaxy S21 5G—not S21+, S21 Ultra or S21 FE.
- Check your regional listing for current availability and exact model compatibility. The cited pages are from Samsung Business UK, Samsung Business South Africa and OtterBox ANZ; they do not establish stock or pricing in other markets.
- If you use Wireless PowerShare, note that Samsung recommends removing both of its cited covers before using the feature. This guidance applies to those Samsung covers, not automatically to every case.
- Treat maker test language as an attributed claim, not as an independent ranking or a promise that a phone will survive every drop.
