I had my s25 delivered and it was doing auto shutdowns and restarts throughout the day. I contacted BM and they sent a replacement asap.and I cannot fault it. I paid for premium and it basically is immaculate. You'd never know it wasn't from Samsung itself. 3rd phone purchased from here. 2 iPhones and an s25 over the last few years.

Really happy with the phone I received. Some slight wear on some of the edges but I didn't choose the pristine option so it's as I would have expected. Most importantly the screen is perfect and the camera is perfect. Overall extremely happy - thanks!

The Galaxy S25 brings Samsung’s flagship range up to date for 2025, delivering a fresh set of features while building on what previous Galaxy S models did well. As the first device in the S series launched this year, it puts performance, display quality, and advanced imaging firmly on the map—without getting too flashy for the sake of it. A solid option for those wanting the latest tech without feeling like they’re chasing trends for the sake of it.

Key features:

Release Date: January 2025
Display: 6.2-inch Dynamic AMOLED 2X, up to 120Hz refresh rate
Processor: Snapdragon 8 Gen 4 for Galaxy (or Exynos 2500, depending on region—check your local specs)
Camera: Triple rear setup with 50MP wide, 12MP ultra-wide, and 10MP telephoto (capable of 3x optical zoom)
Operating System: Ships with Android 14 and Samsung’s One UI 6.1 interface
Build: Armour Aluminium frame with Gorilla Glass Victus 3 on front and back
Connectivity: 5G support, Wi-Fi 7, Bluetooth 5.3
Ingress Protection: IP68 dust and water resistance

Who is this for?

The Galaxy S25 is designed for tech-forward users who want smoother performance, crisp visuals, and reliable camera features. It’s a safe bet for professionals, urban commuters, keen photographers, and anyone who spends a lot of time multitasking or content streaming. Unlike the larger Ultra models, the S25 keeps things more compact and pocket-friendly, making it ideal for those who want a flagship—without carrying a small tablet in their pocket. If you’re using a Galaxy S22 or earlier, you’ll notice sharper cameras and a distinctly punchier display. However, those after specialist pro camera features (like a periscope lens) may prefer the Galaxy Ultra models instead.

Pros & Cons:

Pros	Cons
Vivid, ultra-smooth display with 120Hz refresh rate.	No expandable storage—you’re stuck with what’s built in.
IP68 rating gives peace of mind for daily messes.	Triple camera system is flexible but not quite “pro” level for hardcore photographers.
Snappy performance for gaming, streaming, and productivity.	While it’s lighter than the Ultra, smaller size means a smaller screen—streaming fans may want more space.

Why refurbished?

Choosing a refurbished Galaxy S25 is a practical and planet-friendly way to get flagship features without unnecessary waste. Back Market ensures every device is thoroughly checked and meets strict quality standards before reaching your hands. Read more about our quality process here.
