- Grip-friendly surface with a refined texture that resists fingerprints and slips from your hand, even during busy days or on the go.
- Raised bezels for protection shield the screen and camera lenses when you place your phone on a table or tumble it onto a surface, helping prevent surface scratches and scuffs.
- Tactile button access preserves the responsive feedback you expect from the Galaxy S26 Ultra’s power and volume controls, so you don’t have to press harder or fumble.
