Note Assist

AI-powered note organization automatically summarizes, formats, and translates your notes. Meeting recordings become structured summaries. Handwritten S Pen notes convert to formatted text with intelligent categorization.

Chat Assist

AI helps compose messages in appropriate tones for different contexts. Professional emails, casual texts, or formal documents - describe what you need, and the AI drafts accordingly. It also translates messages in real-time across messaging apps.

S Pen Integration

The integrated S Pen slides into the body of the phone, always ready for use. The near-zero latency makes handwriting feel natural, while Air Actions enable remote control gestures. The S Pen transforms the S25 Ultra into a productivity device that rivals tablets.

Frequently Asked Questions

Is the S25 Ultra worth the upgrade from S24 Ultra?

The upgrade is meaningful if you value Galaxy AI features and the performance improvements. The camera and display are refined rather than revolutionary. S23 Ultra and earlier users will notice substantial improvements.

How does it compare to iPhone 16 Pro Max?

Both are exceptional. S25 Ultra offers more customization, S Pen, and AI features. iPhone excels in video quality and iOS ecosystem. The camera systems are competitive. Choose based on OS preference and specific feature priorities.

Is the 200MP camera really useful?

For most shooting, the pixel-binned 12MP mode produces better results. The full 200MP is valuable for extreme cropping, large prints, and scenarios where maximum detail matters. Having the option is valuable; it's not needed for every shot.
