Samsung Galaxy S25 Ultra Review: The AI-Powered Flagship

Overview

The Galaxy S25 Ultra isn’t just a spec bump—it’s Samsung’s definitive answer to the question “what can a phone do in 2026?” Powered by the Snapdragon 8 Elite and deeply integrated with Google’s Gemini AI, it pushes the boundaries of what we expect from a mobile device. While the iterative design might feel familiar, the internal overhaul makes this the most capable Android smartphone ever built.

Design & Build

Samsung refined the titanium frame from the S24 Ultra, rounding the corners slightly for a more comfortable grip. The flat display (no more curved edges) is a welcome change for S Pen accuracy and screen protector compatibility. At 218g, it’s lighter than its predecessor despite the same 6.9” display size.

The matte back glass resists fingerprints admirably, and the titanium sides feel genuinely premium without being slippery. The IP68 rating remains, ensuring dust and water resistance.

Display Experience

The 6.9” Dynamic AMOLED 2X display reaches a staggering 3000 nits peak brightness, making it fully visible even in direct desert sunlight. The 120Hz LTPO panel drops to 1Hz for always-on display, preserving battery. Color accuracy is class-leading—Samsung’s display calibration remains unmatched, with vibrant but accurate colors in “Natural” mode. The new Gorilla Glass Armor 2 reduces reflections by 75%, which is a game-changer for outdoor visibility.

Galaxy AI: A Deep Dive

This is where the S25 Ultra truly differentiates itself. Samsung has moved beyond simple gimmicks to integrate AI into the core workflow of the device.

1. Circle to Search (Enhanced)

The partnership with Google has matured beautifully. Holding the home bar and circling anything on screen—a landmark in a YouTube video, a pair of shoes on Instagram, or text in an image—instantly pulls up relevant search results. It feels magical and is now faster than ever thanks to the Snapdragon 8 Elite’s NPU.

2. Live Translate & Interpreter

Imagine calling a hotel in Tokyo and speaking English while they hear Japanese, and vice-versa, in real-time. Live Translate now supports 20 languages and works in third-party apps like WhatsApp and Telegram. The Interpreter mode uses the Galaxy Buds to translate face-to-face conversations, displaying the translation on your phone screen while playing the audio in your ear.

3. Note Assist & Transcript Assist

For professionals and students, this is the killer feature. Record a lecture or meeting, and the AI will transcribe it, distinguish between speakers, and generate a concise bullet-point summary. Note Assist in Samsung Notes can format messy scribbles into structured meeting minutes automatically.

4. Generative Edit

Photo editing gets a massive boost. You can remove unwanted objects, resize subjects, or even generate new backgrounds. The results are surprisingly natural, often indistinguishable from the original shot.

Software & Longevity (One UI 8)

The S25 Ultra launches with One UI 8 based on Android 16. Samsung has cleaned up the interface, smoothing out animations to rival iOS. The “Quick Panel” is more intuitive, and customization options are endless.

Samsung promises 7 years of OS and security updates, meaning this phone will be supported until 2033. This matches Google’s Pixel promise and sets a new standard for longevity in the Android world.

Performance: The Powerhouse

The Snapdragon 8 Elite for Galaxy is a beast. In Geekbench 7 scores, it rivals desktop-class silicon. What does this mean for you?

• Gaming: Genshin Impact and Resident Evil Village run at a locked 60fps/120fps with ray tracing enabled.
• Multitasking: You can run three apps simultaneously in split-screen without a stutter.
• AI Processing: Most Galaxy AI features run strictly on-device, ensuring privacy and speed without needing a data connection.

The phone runs noticeably cooler than the 8 Gen 3, thanks to a larger vapor chamber cooling system.

Camera System

The camera array remains versatile but sees significant processing improvements:

• 200MP Main (f/1.7): Captures staggering detail. The new AI-powered processing pipeline produces natural-looking photos with less aggressive HDR and sharpening than previous generations.
• 50MP 5x Telephoto: The real star. It captures sharp, usable images even in low light at 10x and good ones up to 30x.
• 12MP Ultrawide: Improved edge distortion correction and macro capabilities.

Video capabilities are pro-grade: 8K at 30fps, 4K at 120fps, and a new Director’s View Pro mode that lets you preview and switch between all cameras during recording with separate ISO controls.

Competition

• iPhone 17 Pro Max: Example of stability and ecosystem lock-in. The iPhone wins on video quality and app optimization, but the S25 Ultra dominates in multitasking, zoom capabilities, and AI utility.
• Google Pixel 10 Pro: The Pixel has smarter call screening and exclusive camera features (Best Take), but its Tensor G6 chip still lags behind the Snapdragon 8 Elite in raw power and efficiency. The S25 Ultra feels like a more premium, “do-everything” device.

Final Review

The Galaxy S25 Ultra is the Swiss Army knife of smartphones. It excels at photography, productivity, and entertainment while adding genuinely useful AI features that respect your time. The starting price of €1299 is the only real barrier—but if you’re a power user who wants the absolute best Android experience with support that lasts nearly a decade, this is the only phone to buy.
