this far, this device is working great. My only 'issue' was transferring data from my Pixel to this S25 Ultra. I installed the Samsung app on both phones and the app did transfer the 'service' to the Samsung but I ended up manually installing all the apps. Tedious process but it's done and the Samsung is much quicker and the battery life is much longer. 2 things I've noticed over the last few days.

The Phone is great, in perfect condition and works as if I bought it new - and I get a 30 day return option and 1 year warranty included! I love Back Market. I also bought my Mac laptop 6 years ago from Back Market and I still love it and it works perfectly to this day,

This is my 4th phone that I've purchased from back market. Previously purchased phones for my grandson and a work phone. This phone is an upgrade from my original phone. Received it quickly and arrived in excellent shape. Now I have to figure out how to use it, I had a Note 8 before and updated to 25 Ultra.

The Samsung Galaxy S25 Ultra is the 2025 flagship in Samsung’s Galaxy lineup, blending an expansive display with powerhouse hardware and a sophisticated camera array. Even as the newest Ultra model, it offers iterative improvements over its predecessor—think sharper photos, a slightly more refined build, and subtle upgrades where it counts. For anyone who needs the best Android has to offer (at least until the S26 shows up), this pre-owned device keeps you at the front of the pack without contributing to electronic waste.

Key features:

Release Date: January 2025
Display: 6.8-inch Dynamic AMOLED 2X, QHD+ resolution, 120Hz refresh rate
Processor: Snapdragon 8 Gen 4 (or Exynos 2500, depending on region)
Camera: Quad rear cameras: 200MP wide, 12MP ultra-wide, 50MP periscope telephoto, 10MP telephoto
Operating System: Ships with Android 15 and One UI 7
Build: Aluminum frame with Gorilla Glass Armor
Connectivity: 5G ready, Wi-Fi 7 for ultra-fast wireless speeds
Stylus: Integrated S Pen support

Who is this for?

The Galaxy S25 Ultra is best suited for power users, creative professionals, or anyone who wants a top-tier camera setup and a huge, vibrant display. If you’re using an S23 Ultra, the jump isn’t dramatic—think small refinements—but if you’re ready for Samsung’s latest (without waiting for the S26), this model delivers the essentials: speed, versatility, and S Pen multitasking.

Pros & Cons: Pros Cons Excellent camera system for photography and video work. Noticeably large and heavy—not pocket-friendly for everyone. Vivid, bright QHD+ display with smooth 120Hz refresh. Incremental upgrades over S24 Ultra—minimal if you're coming from last year's model. Fast performance from Snapdragon 8 Gen 4/Exynos 2500 chips. Some features (like stylus support) are underutilized for casual users.
Why refurbished?

Choosing a refurbished Galaxy S25 Ultra means less e-waste and more tech joy. Each device at Back Market passes strict quality checks and comes with our transparent standards, so you can buy pre-owned without stress. Learn more about our quality standards.
