The Samsung Galaxy S21 Ultra remains one of the best Android phones we’ve tested here at XDA. It’s not readily available to buy directly from Samsung at this time, but you should be able to get a new or refurbished unit from a retailer. Everything about this phone screams excellent, and it holds up very well in 2023 against other flagships on the market. It’s also arguably a better looking phone compared to the Galaxy S22 Ultra thanks to its beautiful glass design and wrap-around camera. But it’s fragile like a lot of the other flagships on the market right now, which is why we recommend picking up a case to protect it from accidental drops and scuffs.


The Galaxy S21 Ultra is now two years old, so there are plenty of cases on the market. If you are wondering which case to buy now, you are in the right place. Here’s our pick of the best Galaxy S21 Ultra cases you can buy in 2023.
