Samsung officially unveiled the Galaxy S26 Ultra on 25 February 2026, positioning the flagship not just as a hardware refinement but as the inaugural "Agentic AI" phone. While the device maintains its starting price of £1,279 ($1,299), it introduces transformative hardware, including a world-first privacy-focused display and significant boosts in computational throughput.
A Return to Aluminium: Design and Materiality
In a surprising shift from the titanium trend, the Galaxy S26 Ultra utilises an Armour Aluminium 2.0 frame. Samsung engineers opted for aluminium to achieve the slimmest Ultra profile to date (7.9mm) and to enhance heat dissipation from the powerful new chipset. The device is also lighter than its predecessor at 214 grams, and the sharp edges of the S25 Ultra have been replaced with rounded corners for a more ergonomic in-hand experience. The rear of the phone debuts a new "camera island" design that integrates most lenses into a single elevated structure.
The Groundbreaking Privacy Display
The S26 Ultra’s most discussed innovation is its built-in Privacy Display, powered by second-generation Flex Magic Pixel technology (LEAD 2.0). Unlike stick-on filters, this is a hardware-level feature that controls how pixels disperse light.
· How it Works: The display uses a "Black Matrix" of both wide and narrow pixels. When activated, the narrow pixels collimate light forward at a 90-degree angle, making the screen appear black or grey to bystanders.
· Performance: Independent testing shows side-angle visibility drops to less than 1% at 60 degrees compared to 40% on standard screens.
· Customisation: Users can set the display to activate automatically for specific apps (like banking), notification pop-ups, or whenever entering a PIN.
While revolutionary, reviewers noted that the hardware required for this feature results in slightly narrower viewing angles and minor colour shifts even when the mode is turned off.
Performance and Agentic Intelligence
The device is powered exclusively by the Snapdragon 8 Elite Gen 5 for Galaxy, paired with up to 16GB of RAM on the 1TB tier. This customized chipset delivers a 39% boost in NPU performance, specifically to facilitate background AI orchestration. To manage the increased heat, a redesigned Vapor Chamber provides 21% better thermal performance.
· Now Nudge: Proactively suggests actions based on on-screen context, such as finding trip photos if a friend asks for them.
· AI Call Screening: An autonomous receptionist that can answer unknown numbers, summarise caller intent in real-time, and take text-based responses.
Pro-Grade Optics: Seeing in the Dark
Samsung has significantly improved the light-gathering capabilities of its camera system. The 200MP main camera now features a wider f/1.4 aperture, capturing 47% more light than the previous model. The 50MP 5x telephoto lens also received an upgrade to f/2.9, allowing for 37% more light capture.
New creative tools include Horizontal Lock, which keeps the video horizon level regardless of phone rotation, and the APV (Advanced Professional Video) codec for lossless, high-bitrate recording suitable for professional editing.
Charging and Longevity
The S26 Ultra finally addresses charging speeds with Super Fast Charging 3.0, moving to 60W wired charging. This allows the 5,000mAh battery to reach a 75% charge in just 30 minutes. Wireless charging has also been bumped to 25W (Qi 2.2).
Samsung continues its industry-leading commitment to sustainability with a "7-7-7" promise: seven years of OS updates, One UI upgrades, and security patches, ensuring the device remains functional until at least 2033.
