Build Quality – Samsung Galaxy S25
Samsung Galaxy S25 series also offers the world-class build quality encapsulating solids materials with proper engineering. The S25 and S25+ are built on a Samsung Armor Aluminum frame that offers light weight and durability, while the S25 Ultra offers an even sturdier titanium frame for Rugged Green toughness with sumptuous tactility. In spite of its paper-thin profile, the S25 Edge features a reinforced frame architecture providing structural rigidity.

Gorilla Glass Victus 3 also offers a good degree of scratch and everyday wear resistance for both the front and back panels. The S25 Ultra also adds Gorilla Armor 2, which is aimed at reducing glare more than anything else and offers better outdoor visibility while providing more drop protection.
Each one is IP68-rated for dust and water resistance, which means you can submerge them in up to 1.5 meters of water for 30 minutes without issue. The button presses as well as the port seals are engineered to be firm so they hold but do not obstruct, this keeps a good tactile feedback.
The M13 Series machining, tolerances and feel make the Galaxy S25 look as tough as can be on its way to launch day. It does not really matter which one you get as they are all built like tanks; The S25 (compact), the S25+ (bigger), the Ultra, and the Edge.
