Galaxy S26 Ultra Galaxy AI: Deep Dive on Every Feature (2026)

Samsung was first to brand “AI on the phone” as a complete product strategy with Galaxy AI in early 2024. Three iterations later, the Galaxy S26 Ultra ships the broadest AI feature set of any phone in 2026 — broader than Apple Intelligence, broader than Google’s Pixel AI by feature count, if not always by polish.

After four weeks with the S26 Ultra, here’s the complete breakdown of what it actually does.

The hardware

The 55 TOPS NPU is currently the highest on any consumer phone in 2026 — ~22% faster than Apple’s A19 Pro Neural Engine on standardized AI benchmarks. In practice, the gap is smaller than the spec suggests because of software efficiency differences.

Every Galaxy AI feature

Camera + Photos

Generative Edit (the headline feature):

• Object removal (excellent on simple backgrounds, good on complex)
• Move and resize subjects within frame (Apple cannot do this in 2026)
• Generate replacement backgrounds (Apple cannot)
• Expand frame using generative fill / uncrop
• Object replacement (“change this car to a sports car”) — mixed but sometimes impressive
• Watermarks output as AI-edited

ProVisual Engine:

• Real-time AI scene optimization
• AI noise reduction in low light
• Sky replacement
• Adaptive HDR

Best Face (post-shot face swap from burst): Same as Pixel’s Best Take. Works well on 4-6 people.

Communication

Live Translate (calls):

• In-call real-time translation
• 25+ languages cloud, 13 on-device
• 0.8-1.5 second latency
• Works in third-party apps (WhatsApp, etc.)

Chat Assist (messages):

• Rewrite in 5 tones (formal, social, friendly, polite, professional)
• Translate inline
• Spelling/grammar fix

Note Assist (Samsung Notes):

• Summarize long notes
• Auto-format into bullet/outline
• Translate notes inline
• Generate cover images (basic)

Interpreter (face-to-face translation):

• Two-pane split screen for live interpretation
• 13 languages on-device
• Useful for travel, business meetings

Browsing + Search

Circle to Search (Google partnership):

• Circle anything on screen → Google search
• Works in any app
• Reverse image search
• Solves math problems

Browsing Assist (Samsung Internet):

• Summarize webpages
• Translate
• Reading mode + AI clean-up

S Pen Features

Sketch to Image: Draw a rough sketch, AI generates a polished image (basic — comparable to early Image Playground).

Text to Image (gallery): Generate images from text prompts. Powered by Imagen 3.

Note transcription: S Pen handwriting → typed text in 30+ languages.

System-Wide

Now Brief: AI dashboard of your day (weather, calendar, smart home, traffic). Useful, light AI.

Now Bar: Persistent strip on lock screen with smart contextual info (transit, food order, ride share). One of the better lock-screen designs in 2026.

Modes & Routines: Trigger automations from contexts (location, time, app launch). Not new, but AI-suggested routines are.

What’s annoying about Galaxy AI

• Discoverability is poor. Features are buried in submenus you’d never find without a guide.
• Subscriptions are coming. Samsung confirmed in early 2026 that “advanced Galaxy AI” goes paid in late 2026. The base tier remains free.
• Bloat aesthetic. One UI sometimes presents AI features in slightly cluttered ways.
• Some features regional. Live Translate availability varies by country.
• Battery cost. AI features are visibly battery-hungry on the S26 Ultra (more than iPhone 17 Pro under similar load).

Pros and cons

FAQ

Will Galaxy AI features cost money in 2026?

Yes, some. Samsung confirmed that “advanced features” go behind a subscription in late 2026 (date unconfirmed). The basics — Live Translate, Generative Edit, Note Assist, Chat Assist — remain free for the lifetime of the device. Advanced video AI features and unlimited cloud processing will require payment.

Can the S26 Ultra run Llama 3 locally?

Yes, like all Snapdragon 8 Gen 4 phones. See our Llama 3 on Snapdragon 8 Gen 4 step-by-step guide. Expect 15-18 t/s on Llama 3 8B Q4 via MLC Chat.

How does Galaxy AI compare to ChatGPT on a phone?

Different products. Galaxy AI is a collection of focused features (translation, editing, summaries) using small on-device models + cloud for harder tasks. ChatGPT on your phone is a frontier model accessed via API or app. Galaxy AI is integrated into the OS; ChatGPT is a separate app. They complement each other for most users.

Is the S Pen worth it for AI workflows?

If you take notes, draw, or annotate documents — yes. Samsung Notes + S Pen + AI is the best note-taking-with-AI experience on any phone, period. If you don’t use a stylus, you’re paying ~$200 in price premium for a feature you won’t touch.

Will Apple/Google catch up on Generative Edit?

Eventually. Apple has consistently been more conservative on generative AI in photos (they don’t want to be sued / blamed for synthetic imagery). Google’s Magic Editor is closer to Samsung’s but slightly less ambitious. Don’t expect parity in 2026.

What’s the camera advantage of the S26 Ultra?

The 200 MP main sensor + 5× periscope + AI processing combination is currently best-in-class for telephoto-heavy use cases. The night mode + ProVisual Engine is meaningfully better than iPhone 17 Pro for extreme low light. For daylight, all three flagships are within 5% of each other.

Bottom line

Les Galaxy S26 Ultra is the most ambitious AI phone of 2026 — broadest feature set, strongest silicon, S Pen + AI combination that nobody else offers. If you actually use AI features daily, you’ll find more to use on the Galaxy than on any other phone.

The tradeoffs are real: weaker privacy than iPhone 17 Pro, paid tier arriving, battery cost, and discoverability issues. For users who prioritize feature breadth over polish, S26 Ultra is the buy. For users who prefer fewer features done elegantly, iPhone 17 Pro is the alternative.

Either way, you’ll have AI capability you’ll genuinely use in 2026 — both phones are well past the “AI demo” tier and into “AI tool” tier.
