The Samsung Galaxy S25 is one of the best-selling Android smartphones in Portugal—and for good reason. But with a price tag exceeding €900 for the Ultra model, protecting it with a good case is a decision that pays for itself. In this guide, we explain everything about the Galaxy S25 series, what’s changed from the previous generation, and which InstaCase model makes the most sense for each device.
The Samsung Galaxy S25 lineup — five models, five sizes
The Galaxy S25 series is the largest lineup Samsung has released to date, with five different models. The cases are not interchangeable between models—always check your model before purchasing.
| Model | Featured | Screen | Thickness |
|---|---|---|---|
| Galaxy S25 | The most compact model in the line | 6.2 inches | 7.2 mm |
| Galaxy S25+ | Larger screen, longer battery life | 6.7 inches | 7.3 mm |
| Galaxy S25 Ultra | Top of the line, with built-in S Pen | 6.9 inches | 8.2 mm |
| Galaxy S25 Edge | The thinnest in the line | 6.7 inches | 5.8 mm |
| Galaxy S25 FE | Fan Edition, best price | 6.7 inches | 7.7 mm |
You can check your exact model under Settings → About Phone → Model Information.
What's new with the Galaxy S25 that affects your choice of case?
The Galaxy S25 Edge — the thinnest ever The S25 Edge is just 5.8mm thick — comparable to the iPhone 17 Air. It’s the thinnest model Samsung has ever released, and just like the Air, a case that’s too bulky completely undermines its design.
Redesigned camera module The lens layout on the S25 is different from that of the S24—covers from the previous generation will not fit properly. Always check for compatibility with your specific model.
S Pen on the S25 Ultra The Galaxy S25 Ultra keeps the S Pen integrated into the body of the device. A case for the S25 Ultra must have the correct cutout for the S Pen—without it, you won’t be able to remove or store the pen while the case is on. All InstaCase cases for the S25 Ultra have this cutout.
More compact design on the base S25 The Galaxy S25 is the most compact flagship Android smartphone on the market—smaller and lighter than any comparable iPhone.

What to look for before buying a case for the Galaxy S25
Compatibility with the exact model: The S25, S25+, S25 Ultra, S25 Edge, and S25 FE have different dimensions. Always check the model before purchasing.
S Pen Cutout (S25 Ultra) Essential for the Ultra — without this cutout, you won't be able to use the S Pen with the case on.
Camera module cutouts The S25 has a new camera layout. Generic cases may not have the cutouts in the right place, partially covering the lenses.
Wireless Charging Compatibility All InstaCase Samsung cases are compatible with wireless charging. The Premium Glossy model includes MagSafe for optimized charging.
Frequently Asked Questions
Do Galaxy S24 cases fit the S25? No—the camera module has been redesigned and the dimensions are slightly different. Cases are not compatible across generations.
Does the Galaxy S25 Edge need a special case? Not necessarily a special one, but it should be slim. A standard case can almost double the thickness of the device. Go for the Compact to keep it slim.
Are InstaCase cases for Samsung different from those for iPhone? The designs are the same, but the structure is specific to each model—the cutouts, dimensions, and button placement are tailored to each device.
