While the Samsung Galaxy S21+ isn't as impressive as last year's Galaxy S22+ and the current-gen Galaxy S23+, it's still a great phone for most people. It offers flagship-level performance, thanks to Qualcomm's Snapdragon 888 SoC, a gorgeous high refresh rate display, an impressive triple camera setup, and great battery life. On top of that, Samsung has kept it up to date with the latest software updates, so there's little reason for those of you who already own one to upgrade to one of the newer models.

However, like most modern smartphones, the Galaxy S21+ is prone to wear and tear. Its glass back and aluminum frame can easily pick up scratches and even shatter if you accidentally drop your phone. Therefore, you should keep yours in a case to keep it going for another couple of years. While we're sure most of you already own a case for the device if you're looking to upgrade, here are our top picks for the best Galaxy S21+ cases in 2023.

Those are the best Galaxy S21+ cases currently on the market. If you're wondering which one to pick, then we highly recommend the Spigen Liquid Air case. It offers complete scratch and drop protection and has a textured back for a reassuring grip while still maintaining a slim profile. But if it's a bit too simple for you and you want better drop protection, the Urban Armor Gear case is a great alternative. It's definitely not as slim as the Spigen Liquid Air, but it's still quite lightweight and has a five-layer design for military-grade drop protection.
