Is the Galaxy S21+ worth protecting?

When you've had a device for over two years, it's easy to get swept up in the allure of a new one and neglect to protect your current device — but that's not the case with the Galaxy S21+. Despite being relatively old, this smartphone refuses to leave you feeling outdated. It offers solid performance, enough to go toe-to-toe with recent high-end alternatives. And thanks to the four years of software support, it will continue to sport the latest Android OS and One UI versions for two more years. The S21+ can be compared closely to the latest Samsung Galaxy S23+. And recognizing the significance of such a feat is equivalent to discerning the importance of securing this phone. No further explanation needed!

Getting the right protective cover for your S21+

There's no one-size-fits-all solution when selecting the best case for your S21+. The most appropriate case for you ultimately depends on your personal preferences. For instance, suppose you want a phone cover that perfectly balances durability, visual appeal, and a secure grip. In that case, you'll want to go for the Spigen Liquid Air. On the other hand, if you prioritize protection over everything else and are willing to sacrifice slightly in the sleekness department, you'll be more than satisfied with Supcase's Unicorn Beetle Pro.

Alternatively, if you desire the best of both worlds, in a sense, a case that's both elegant and offers heavy-duty protection, the premium OtterBox PopGrip Symmetry Series is the right way to go. This 360o cover even features an ergonomic pop socket, which enhances the grip around your phone, with the added functionality of acting as a kickstand. Nevertheless, it's important to note that this option is relatively expensive. So, if you're a budget-conscious consumer, you may want to look elsewhere. That's where the Speck Products Presidio2 Grip comes into the picture. It offers all the qualities of a high-end case, including improving grip around your phone. But it does so without costing an arm and a leg.

While the cases above are our favorite picks and excel in their respective use cases, we recommend exploring the other phone covers in our collection. You might find the one that caters to your unique preferences among them. Notwithstanding, while going through the collection, make sure to check out these cases: the ESR phone cover if transparent cases are your thing, the Snakehive Vintage if you're fond of wallet cases, and the S-View Flip cover if you'd rather have the official Samsung case.
