The Samsung Galaxy S25 Ultra is the flagship model from Samsung’s 2025 smartphone line-up, merging cutting-edge hardware with a familiar Galaxy S Ultra design. Three generations on from the S22 Ultra, the Galaxy S25 Ultra elevates mobile photography and productivity, thanks to its expansive display, upgraded chipset, and advanced camera setup. This pre-owned device offers both style and firepower for those who want a big-screen experience without carting a tablet around.

Key features:

Release Date: January 2025
Display: 6.8-inch Dynamic AMOLED 2X, QHD+ resolution, 120Hz refresh rate
Processor: Snapdragon 8 Gen 4 (or Samsung Exynos 2500, depending on region)*
Camera: Quad rear camera system with 200MP main sensor, ultra-wide, 3x and 5x telephoto lenses
Operating System: Ships with Android 15, One UI 7
Build Quality: Armour Aluminium frame, Gorilla Glass Victus 3 (front and back)
Connectivity: 5G support, Wi-Fi 7, Bluetooth 5.4
Stylus: Built-in S Pen for note-taking and creative tasks

Who is this for?

The Galaxy S25 Ultra is best suited for power users, creatives, and professionals who want a robust phone with a huge, vibrant display and top-tier camera features. If you handle a lot of multitasking, rely heavily on productivity apps, or love sketching ideas with a stylus, it’s built for you. Compared to the Galaxy S24 Ultra, the S25 Ultra brings a faster chip and camera improvements. However, if you prefer a smaller phone or don't often use the S Pen, you may find other models handier.

Pros & Cons:

Pros	Cons
Giant, sharp display great for streaming and drawing.	Large size isn’t pocket-friendly for everyone.
200MP camera with versatile shooting options.	Heavier build, which some may find bulky for single-handed use.
Latest Wi-Fi 7 support for fast and stable connections.	Premium features may be more than casual users need.
S Pen included for handwriting and creative tasks.	No microSD slot — expansion fans will miss it (again).

Why refurbished?

Choosing a refurbished Galaxy S25 Ultra is a practical move towards a greener planet, letting tech live a second, third, or fourth life. All devices sold via Back Market undergo in-depth testing and checks—so you get performance you can trust. Learn more about our quality standards.
