Will the Galaxy S26 Ultra Case Fit the S25 Ultra?

So, you're excited about your new Galaxy S26 Ultra and have a big question:will your old Galaxy S25 Ultra case fit?

The answer is a clear NO.

Samsung made some really cool changes to the phone's design. While these new tweaks make the phone better to use, they also mean your old case won't work.

Let's jump in and see why you’ll need a brand new Galaxy S26 Ultra case for your new phone.

Recent leaks from  sources like PhoneArena show Samsung focused on comfort and camera upgrades with the S26 Ultra.

The camera bump is bigger and the phone’s shape is more curved, making a big difference in how you hold it. These changes mean cases need to be made specifically for each model.

Even if you’re tempted to reuse your trusty case, the differences add up quickly. The changes in module size, curvature, dimensions, and internal layout mean a snug fit and full feature compatibility are unlikely.

According to multiple leaks, including case-manufacturer listings, the design shifts are real and significant.

To start, the biggest change is the camera. The new design is a major reason old cases won't fit, as the camera area is entirely different.

Next up, the phone's actual shape and size have been updated. This means a case made for the boxier S25 Ultra won't be able to stretch or bend to fit the new phone's curves.

On top of that, even though the buttons and ports appear to be in the same spot, some minor internal changes were made that affect how a case fits.

Lastly, even minor updates to the phone's materials and edges make a difference. The S26 Ultra has a more refined feel that needs a case made just for it.

Since your old case won't work, it's time to pick out a new one. Choosing the right case can seem tricky with so many options, but don't worry. We've got you covered with a few simple tips to help you find the perfect case for your new phone.

Always look for labels like “Compatible with Galaxy S26 Ultra” rather than assuming older Ultra cases fit. Even models from the same series can differ just enough to matter. Verified listings from the case maker or trusted retailers reduce risk.

Decide what you need: drop protection, scratch resistance, camera bump coverage, or wireless charging compatibility. A review-style case may look sleek, but it won’t help much if you drop your phone. Choose one that suits how you use your phone daily.

With its greater curvature and larger camera island on the S26 Ultra, a case with good grip and edge protection is helpful. Materials like textured TPU, rubberized back, or aerospace-grade composites (yes, like what we use) maintain feel and comfort.

Do you use wireless charging often? Do you carry a stylus (S Pen)? Do you use your phone one-handed, or do you often use it in the car? The right case will accommodate these habits — e.g., one that doesn’t block Qi2 magnets or interfere with the stylus.

A case can look amazing but feel bulky, or feel great to hold but offer little protection. We recommend picking three features you care most about (style, drop protection, wireless charging) and finding a case that hits at least two strongly.

If you’re upgrading or prepping for the next flagship, know this: you’ll want a new case for the S26 Ultra. The changes in the camera module, curvature, materials, and internals mean the older S25 Ultra case simply won’t cut it.
