Design Changes: A Bold New Direction
Samsung Galaxy S26 Ultra
The S26 Ultra is the biggest design evolution in the Ultra line since its inception. Samsung has moved away from the sharp, angular corners of the S22-S25 Ultra series and adopted softer, more rounded corners. The display is still flat, but the overall silhouette is gentler and more comfortable to hold. The frame material changes from pure titanium (S25 Ultra) to a titanium-aluminum composite that is lighter without sacrificing durability.
Key design details:
- Bezels: 1.2mm symmetric bezels -- the thinnest on any smartphone
- Weight: 218g (down from 232g on the S25 Ultra)
- Thickness: 8.1mm (down from 8.2mm)
- Frame: Titanium-aluminum composite
- Glass: Gorilla Armor 2 front (75% anti-reflection)
- S Pen: Embedded, same functionality
Samsung Galaxy S25 Ultra
The S25 Ultra continued the angular design language with sharp corners and a titanium frame. At 232g, it felt premium but noticeably heavier. Bezels measured 1.5mm, and it featured Gorilla Armor front glass (first generation anti-reflective coating).
Design Comparison
| Feature | Galaxy S26 Ultra | Galaxy S25 Ultra |
|---|---|---|
| Corners | Rounded | Angular |
| Frame | Titanium-Aluminum | Titanium |
| Weight | 218g | 232g |
| Thickness | 8.1mm | 8.2mm |
| Bezels | 1.2mm | 1.5mm |
| Front Glass | Gorilla Armor 2 | Gorilla Armor |
| Colors | Silver Blue, Black, Gray, White Sand | Titanium Black, Gray, Silver Blue, White Silver |
The weight reduction of 14g is noticeable in daily use. The rounded corners make the S26 Ultra more comfortable for extended one-handed use, though some longtime Ultra fans may miss the distinctive angular aesthetic.
Display: Brighter and More Refined
Both phones feature Dynamic AMOLED 2X panels with 1-120Hz adaptive refresh rates, but the S26 Ultra pushes the boundaries further.
| Display Spec | Galaxy S26 Ultra | Galaxy S25 Ultra |
