The Galaxy S21 Ultra is the first Galaxy S phone compatible with the Samsung S Pen, which typically only works with the Note series. Its camera module is similar in concept to its predecessor S20, except for its frame, which melds more with the phone’s overall metal design. However, this new design does not house the the S Pen within the phone body. This makes it impossible to carry the Galaxy S21 Ultra S Pen without a Case holder. We are hoping to see a housing in upcoming Galaxy S22 release.
While innovative, this feature also makes the camera more prone to damage on impact, which is why having the phone in a case is essential. So, we’ll be looking at the best Galaxy S21 Ultra cases right here.

What Case is best for Galaxy S21 Ultra?
There are dozens of factors to consider when choosing a phone case, and the heavy and large smartphone like Galaxy S21 Ultra, durability and grip have to be the top consideration.
Our top recommendation is the ESR Metal Stand case and Galaxy S21 Ultra Silicone Cover if you are looking for a thin and ultralight cover. Both offer good grip and scratch protection while keeping your phone safe. Now, as we know, the S21 Ultra is bigger than the Galaxy S21+; you might want to buy a case to hold your credit cards. For that, we suggest Spigen Slim Armor CS.
For heavy-duty cases, we recommend UAG Monarch and Ringke Onyx Series. These are the heavest back covers in our list but offer greater bump and drop protection. Lastly, the official Samsung Rugged Case offers military-grade drop protection and extra functionality such as a kickstand on the back.
If you are looking for luxury style and sleekness, you might be interested in Samsung Leather Cover, available in brown and black colors.
However, you might be into the new S-Pen. If you plan to purchase a new Galaxy S21 Ultra S-Pen, I highly recommend the Samsung Silicone Cover with S-Pen, which is the only compatible case to hold your stylus.
