Overview

Samsung Galaxy S26 Ultra features a 6.9-inch Dynamic AMOLED display with a new "Privacy Display" technology that hides content from side viewing angles. Under the hood, it is powered by the Snapdragon 8 Elite Gen 5 processor, paired with up to 16GB of RAM to support advanced on-device AI. The professional-grade camera system is led by a 200MP main sensor with a wider f/1.4 aperture for superior low-light performance. For longevity, it retains a 5,000mAh battery but reportedly upgrades to faster 60W wired charging, reaching a 75% charge in just 30 minutes. This refined flagship also maintains its signature S Pen integration within a slimmer, more ergonomic 7.9mm titanium frame.
