I wanted to wait until I had this phone for a week before I submitted my review. It's been a week and two days. I must say, I was very skeptical of buying this phone at first because of it being in "fair" condition. I was concerned about it having small scratches, dents, discoloration, etc that may have came with it because of Back Market's description of what a fair product would look like. Plus, the battery option I chose gave me more skepticism. I've purchased from Back Market before. I have a MacBook Pro and Beats Studio Buds + that I purchased from here. So, I have confidence in Back Market's credibility. The only thing about my Macbook was where the previous owner placed their stickers, I can see it. But, other than that, I'm not bothered by it. I really don't see it. It's very faint. It's still a great Macbook. I must be honest and say that this S25 Ultra is by far the best purchase I have made on here. This phone did NOT have a single blemish on it. Heck, there wasn't even a piece of lint on it lol. I am beyond impressed. To think I was gonna buy one in good condition or better blows my mind. This phone should have been considered premium. I can't find anything wrong with it. The battery life on it is absolutely amazing. A days worth under heavy use. Thanks Back Market for another great product! I highly recommend anyone who wants to save a good piece of change to go for the fair option. I have no regrets. The icing on the cake is that it arrived days before it was supposed to be here. 20 out of 10!

I LOVE this phone. It was in like new condition and it does everything I want it to do. If I didn't know that this phone was refurbished, I would not be able to tell. I also loved the purchasing experience on the Back Market site. This is the 3rd personal phone that I've bought from Back Market, and I've recommended Back Market and know 3x people that have purchased phones. No one has had an issue with the phones and are enjoying their phones right now. At this point, I dont really think about purchasing a phone from any other vendor.

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.
