Some cases aren't up to snuff and we're big proponents of protecting your phone. We compiled a list of the best heavy-duty cases so you can keep your flagship safe and protected from the elements.

The S21 is one of the best phones of the year with high-end specifications and high-end style. Sometimes the most expensive phones are also the most vulnerable. Don't you want to make sure your new device is as safe as possible?

The best heavy-duty cases for the S21 are the ones from ArmadilloTek. The case is made to look like a tank and has a kickstand for multimedia use. The Sucnakp Shock Absorption is a more slim yet still protective option if that case is too large for your tastes.

Make sure the case you choose is one of the best from our collection. Be sure to check back for more great options as we update our S21 case summaries frequently.
