The Samsung Galaxy S21 Ultra is the largest and most powerful model of the latest Galaxy S21 series. Unfortunately, it is also the most fragile, as it is the only device to feature glass on both sides of its aluminum frame. So, you may want to consider getting a new case to protect this $1,200 investment.

However, there are some great options from third-party companies, and we have some respected names on the list. We also recommend that you consider the cases from Zagg, Otterbox, Spigen, Incipio, and Olixar, but in the end, the choice is yours. Check them out to see If there’s something right for you, and remember that the prices and protection will vary from product to product.
