The Galaxy S25 Ultra continues Samsung’s design evolution with a refined titanium frame, offering lightweight handling and enhanced durability. The device is thinner and slightly more ergonomic than its predecessor, making it more comfortable to hold despite its massive display.

  • Display: A stunning 6.9-inch Dynamic AMOLED 2X panel dominates the front, with a QHD+ resolution (3200 x 1440), LTPO adaptive refresh rate (1Hz to 144Hz), and peak brightness reaching an astonishing 2,800 nits – ideal for outdoor visibility and HDR content.
