There’s plenty to explore on the Galaxy S25 Ultra, from writing a note with the screen off to choosing the right camera lens and trying Galaxy AI tools. Here are 28 practical tips, grouped by task. Menus and AI features can vary by software version, region, language, account, and app, so check your phone’s installed software when an option is missing.
S Pen tips for notes and on-screen tools
1. Write a note without turning on the display
Enable Screen off memo at Settings → Advanced features → S Pen. With the display off, remove the S Pen and write on the screen. You can change the pen settings or color, erase, save the memo, or pin it to Always On Display using the available memo controls. See Samsung’s S Pen instructions for the documented options.
2. Start a quick note with two taps
Turn on Quick notes in the S Pen settings. Then press and hold the S Pen button and tap the screen twice with the pen tip to open a note.
3. Open Air command for shortcuts
Use Air command to reach supported S Pen tools, including AI Select, Create note, Screen write, Translate, Magnify, Drawing assist, PENUP, and Write on Calendar. The available shortcuts can depend on software and compatible apps.

11. Don’t look for a Bluetooth shutter button
The S25 Ultra’s included S Pen does not support BLE pairing, charging, location tracking, or remote Air actions, so it cannot act as a camera shutter or gesture controller. That limitation does not remove its on-screen tools. Samsung documents the distinction in its S Pen support guide.
Camera tips: choose a lens and workflow
The rear camera system comprises a 50 MP ultra-wide, a 200 MP wide camera, a 10 MP telephoto with 3x optical zoom, and a 50 MP telephoto with 5x optical zoom. Samsung describes 2x and 10x as optical-quality zoom—not as additional optical lenses. These are manufacturer specifications, not a guarantee of results in every scene. See Samsung’s S25 Ultra specifications and product feature details.
12. Use ultra-wide for more of the scene
Choose the ultra-wide camera when the frame needs to include more of a room, landscape, or group. Its wider coverage is the useful distinction; it is not a substitute for moving closer to a subject when detail matters.
13. Start with the main camera for general shots
The 200 MP wide camera is the main option for everyday framing. Choose it when you do not need the broader view of ultra-wide or the tighter reach of a telephoto lens.
14. Pick 3x optical zoom for a tighter view
The 10 MP telephoto provides 3x optical zoom. It offers a tighter field of view than the main camera while using the dedicated 3x telephoto lens.
Do these 3 things before closing this tab:

The 50 MP telephoto provides 5x optical zoom. It is the longer-reach optical option in the listed rear camera set.
16. Treat 2x and 10x as optical-quality zoom
Samsung labels 2x and 10x zoom as optical-quality. Keep that wording distinct from the 3x and 5x optical zoom provided by the dedicated telephoto cameras.

17. Try Expert RAW when you want editing flexibility
Samsung presents Expert RAW as an advanced camera workflow that saves RAW files for flexible editing. RAW gives you a different starting point for post-processing; it does not guarantee a better photo without suitable editing.
18. Try Log Video if you plan to color-grade footage
Samsung describes Log Video as a capture option intended to retain more highlight and shadow detail for later color grading. It is most relevant when you expect to edit the footage, rather than as a promise of a finished look straight out of the camera.

Samsung promotes Nightography video and reduced noise as S25 Ultra features. Results still depend on the scene and capture conditions, so review a test clip before relying on it for an important recording.

Samsung’s current S25 Ultra product page describes the features below. Their availability and exact behavior can vary by region, language, software version, account state, and compatible app. Check the feature on your installed software before building a workflow around it; Samsung’s Galaxy S25 Ultra page provides the manufacturer’s current feature descriptions.
20. Check Now Brief for a daily summary
Samsung describes Now Brief as a Galaxy AI feature. Look for it in the software available on your phone and review what information it can access before relying on it as a daily overview.
21. Try Gemini Live for a live AI conversation
Gemini Live is listed among the S25 Ultra’s AI features. Availability and supported interactions may depend on language, account, region, and installed software.
22. Use Audio Eraser on supported recordings
Samsung describes Audio Eraser as an AI audio tool. Try it on a supported recording and inspect the result; the page does not establish that it works identically across all audio or apps.

- Safe: Extra strong mounting on magnetic surfaces.
- Protection: Sleek design with 6 feet military-grade drop protection.
- Versatile: Integrated twist lock for bikes, motorcycles, cars and more.
- Compatible with MagSafe - Works with most third-party MagSafe compatible accessories.

23. Explore actions across apps
Samsung also describes AI-supported actions across apps. The available actions depend on compatible software and the apps installed, so use the options presented on your device rather than assuming universal app support.
24. Check AI terms before depending on a feature
Do not assume every Galaxy AI feature is free in 2026. Samsung’s US 2025 business specification sheet said Galaxy AI features were free through 2025 and required a Samsung account; that dated statement does not establish current terms. Some basic features and enhanced Samsung or third-party features may have different terms. Check the current notice for the feature and region you use.
More display and setup tips
25. Make use of the large, high-resolution display
The Galaxy S25 Ultra has a 6.9-inch display with a 3120 × 1440 resolution and refresh rate up to 120 Hz, according to Samsung UK’s specification page. Choose display settings to suit your preference for smoothness, detail, and battery use.

Review Air command and keep the shortcuts you actually use close at hand. A smaller, task-focused set makes it easier to find note-taking or screen tools when you need them.
27. Save a screen-off memo you will need later
After writing a screen-off memo, use its controls to save it or pin it to Always On Display when that option is available. This turns a quick capture into something easier to find later.
28. Match the camera mode to what happens after capture
For a straightforward image, use a standard camera mode; choose Expert RAW when you want RAW files to edit, or Log Video when you intend to color-grade video. The right choice depends on your editing plan, not a blanket claim that one mode produces better results.
