phone is great, got in excellent condition, looked brand new no scuffs or scratches to indicate otherwise. only issue I had was how it was shipped. it was in a large box with use a little sleeve of bubble wrap on the phone and a loose piece of bubble wrap but would've been knocking around in the box. I didn't eexpect it to be new in origin box or anything but a bit of padding wouldnt have gone amiss. goes to show that these phones are stronger than they use to be but just felt like an unnecessary risk. overall happy with the phone. it's fun having a stylis again! it's my first refurbished phones. I won't lie i was skeptical but I have no complaints with the phone :)

I got the ultra for £733 at excellent condition! Thought it was gonna come in another packaging because it was "refurbished". but when it arrived, it was brand new, in it's original box! Like, I still got an unbox experience. Everything is functioning really well so far, will have to see months down the line confirm it's consistency but overall, I'm loving it!🙌🏻

Lovely phone, great camera. The phone is as good as new. This replaces my very old Samsung a52s which finally ran out of storage. Excellent service from Black Market

Device appears to be almost new with only tiny unnoticeable signs of wear. After a week of use, I'm completely satisfied that all features are working as expected and battery seems to be in near perfect condition. Very happy with the Back Market experience altogether as delivery was rapid and packaging fine. I will be using them again in the future, now that I know that refurbished can save so much money with very little compromise on the quality of experience.

I ordered the Samsung S24 Ultra in Excellent condition and I’m genuinely impressed. The phone arrived looking almost brand new with no visible issues. Everything works perfectly — the camera, display, battery, and overall performance are excellent. I was a bit unsure about buying a refurbished phone at first, but this experience has been much better than expected. Very happy with the purchase and would recommend it.

Bargain, was looking for an s22 ultra but searched s24 out of curiosity, shame I didnt buy it first time as it was £479, after few days and refreshing slighly went up to £509 but phone in excellent condition for a fair model which was really good. Came in a simple cardboard box and the phone inside, not a visible scratch on the front and rear, couldn't be happier for a model that recent for such a low price and great quality. Definitely worth 👌

The Galaxy S24 Ultra brings a big, bold Android experience, even as we cruise into 2025. This is Samsung’s flagship from January 2024, packing advanced camera hardware, a generous 6.8-inch display, and an integrated S Pen for productivity or the occasional doodle in meetings. Released just one generation ago, it straddles the line between premium performance and features that are (finally!) more than just upgrades-for-upgrades’-sake.

Key features:

Release Date: January 2024
Display: 6.8-inch QHD+ Dynamic AMOLED 2X, up to 120Hz refresh rate
Processor: Snapdragon 8 Gen 3 for Galaxy (or Exynos 2400, depending on region)
Camera: Quad rear system: 200MP main, 12MP ultra-wide, 50MP telephoto (5x optical zoom), 10MP telephoto (3x optical zoom)
Operating System: Ships with Android 14 and Samsung One UI 6.1
S Pen: Integrated stylus for sketching, note-taking, and quick controls
Build: Armour Aluminium frame with Gorilla Glass Armor (front and back)
Connectivity: 5G support, Wi-Fi 7, Bluetooth 5.3, USB-C

Who is this for?

The Galaxy S24 Ultra is ideal for power users, creative professionals, and anyone who values a big screen and high-end photography on their phone. The S Pen makes it a handy tool for note-takers, designers, or anyone keen on annotating screenshots at speed. Compared to the Galaxy S23 Ultra, the S24 Ultra edges ahead with an upgraded chipset and sharper telephoto capability, but the size might be a drawback for those who prefer pocket-friendly phones.

Pros & Cons:

Pros	Cons
Outstanding camera system – versatile for all lighting conditions and use cases.	Size and weight make one-handed use a challenge.
Vibrant 6.8-inch QHD+ screen with smooth 120Hz refresh rate.	No microSD slot for expandable storage (unsurprisingly, in 2024).
S Pen adds versatility for creative and productivity tasks.	Lots of features that some users may never use.
Durable build with water and dust resistance (IP68).	May feel overpowered for light or casual users.

Why refurbished?

Choosing a refurbished Galaxy S24 Ultra helps extend the life of a high-spec device, minimising e-waste and giving impressive tech another round in the ring. All pre-owned devices on Back Market undergo tough quality checks for total peace of mind. Discover how we guarantee quality on refurbished phones.
