Samsung launched the Galaxy S21 lineup back in January 2021. Sitting in the middle of this lineup is the Galaxy S21 Plus, offering a 6.7 inch display, a 120Hz refresh rate, a Snapdragon 888 processor (Exynos 2100 outside the US), a triple camera system, a 4000mAh battery, and more. The fact the Galaxy S21 Plus has a larger display than the regular S21 and a cheaper price tag than the Galaxy S21 Ultra will make it a very attractive option for many people. If you’ve already purchased the Galaxy S21 Plus or are planning on getting one, you don’t want to shatter or scratch it.

But unfortunately, accidental drops, spills, and bumps do happen. To protect your shiny toy, you should purchase a case. Phone cases come in a wide variety of colors and patterns, allowing you to personalize your device. What’s great is many cases cost less than $25 and are a bargain. In this article, we’ve rounded up the best cheap cases for the Galaxy S21 Plus. You don’t have to spend too much to protect your phone!
