Enhanced Camera Capabilities
Pro Mode for Precision Photography
Most users are familiar with the Galaxy S25 Ultra’s incredible camera specs, but have you unlocked the potential of Pro mode? This feature turns your phone into a professional-grade camera by giving you control over shutter speed, ISO, focus, and white balance. Whether you’re dimming the lights for a moody indoor shot or capturing fast-moving action, Pro mode ensures you get the perfect shot every time.
Astrophotography Mode
Night owls and stargazers will love the inclusion of astrophotography mode. This hidden gem allows you to capture stunning images of the stars, constellations, and even passing meteors. With longer exposure times and AI processing to reduce noise, your nighttime shots will rival those taken on a DSLR.
Enhanced Zoom Functions
The “Space Zoom” feature gets an upgrade with the S25 Ultra’s ability to zoom up to 200x. But the real magic is in its AI-packed stabilization, reducing the blur often seen with high zoom levels. Whether you’re zooming in on wildlife from a safe distance or reading tiny text across the room, the enhanced zoom allows for pinpoint accuracy.
Customization Options
Unlock Advanced One UI Tweaks
Samsung’s One UI has always been a favorite for those who value both design and functionality, but the S25 Ultra takes it to another level. Using the Good Lock modules, you can tweak everything on your phone—from creating custom lock screens to changing the way your multitasking menu works.
Notable tweaks include the ability to adjust the shape and size of app icons, rearrange quick settings toggles, and even customize your keyboard layout right down to specific shortcuts. For those who love control, Good Lock makes the experience uniquely yours.
Theme Customization
Want to match your phone’s theme to your mood or outfit? The Galaxy S25 Ultra’s advanced theming options allow you to align your device’s colors with your wallpaper seamlessly. You can apply textured effects, gradient backgrounds, or build your own theme using the Galaxy Themes app.
Performance Optimization
Gaming Mode for Seamless Play
The S25 Ultra isn’t just for professionals; gaming enthusiasts can rejoice too. Samsung’s dedicated gaming mode optimizes performance by allocating resources efficiently, ensuring smoother gameplay and uninterrupted sessions. Coupled with the new cooling system, you won’t have to worry about overheating, even during intense multiplayer matches.
Additionally, Galaxy Game Launcher allows you to block calls and notifications, freeing you from distractions as you crush your high scores.

For those always on the go, the latest adaptive battery-saving options are a game-changer. The enhanced AI-powered system adjusts app usage and screen settings to preserve energy, extending your phone’s battery life for hours.
Productivity Tools
Enhanced DeX Mode
Samsung DeX has long been a standout feature for professionals, allowing your phone to work like a desktop. On the S25 Ultra, DeX takes productivity further by offering wireless connectivity to any compatible monitor or smart TV. With improved multitasking support, you can run multiple windows or apps side by side with ease.
S Pen Tricks
Many users love the S Pen for its precision, but it’s not just a note-taking tool. The Galaxy S25 Ultra introduces remote gesture controls that take the experience to the next level. Take presentation navigation, for example. With the S Pen, you can move through slides using simple hand gestures without even touching your phone.
You can also use it as a Bluetooth camera shutter or program custom commands to streamline workflows for tasks like document editing or app management.
Multitasking Made Easy
Thanks to the expanded App Pair feature, multitasking has never been easier. Pair up your favorite apps to open them simultaneously in split-screen mode. For example, you can browse reference material in Chrome while taking notes in Samsung Notes side by side.
