love the phone. excellent condition. one issue though, it had not been fully factory reset so still had many apps (Spanish) installed and phone language was set to Spanish. Apart from this minor inconvenience, it's a great phone at a very good price.

I spent several days searching for the best deal and found black market was the cheapest in fact it was €90 cheaper than The number one ref Farb website. Delivery everyone else was five days where with black market it was only two.: will definitely be using again.

Its been up and running for a few days and it seems almost perfect. Except for a very light scuff mark on the back cover, I can't tell it from new. The phone was dispatched quickly and delivered via a tracked service with one of the big couriers. The price was good, especially considering S23 Ultras seem to be holding their values well. My only slight disappointment was at the time of ordering - a 12gb RAM version was not available. The S23 Ultra is the last Samsung to have a 10x optical zoom on the camera so I'm delighted to get such a good example.

Got the excellent condition model and you'd never know it's not brand new. I'm delighted with it, this feels like a brand new phone, battery is in great condition. Will never buy a brand new phone again.

Brilliant device, may as well be brand new! Only issue is the S-pen is really stuck in there and needs an implement to remove.

The Samsung Galaxy S23 Ultra is a flagship smartphone that made its debut in February 2023. While it’s now a generation behind Samsung’s latest, this model still stands tall thanks to its advanced display, high-resolution camera setup, and robust performance. For those looking for top-tier specs in 2025, the S23 Ultra remains a savvy, future-proof choice, especially when you’re happy to use something that’s less-than-brand-spanking-new—but still every bit as sharp.

Key features:

Release Date: February 2023
Display: 6.8-inch Dynamic AMOLED 2X, QHD+ (3088 x 1440 px), 120Hz refresh rate
Processor: Qualcomm Snapdragon 8 Gen 2 for Galaxy (global parent spec)
Camera: Quad rear camera system: 200MP wide, 12MP ultra-wide, 10MP telephoto (3x), 10MP periscope telephoto (10x optical zoom)
Operating System: Ships with Android 13 (upgradable via Samsung’s One UI)
Wi-Fi: Wi-Fi 6E support
Extras: S Pen stylus support, IP68 dust and water resistance, Gorilla Glass Victus 2 front/back, Armour aluminium frame
Connectivity: 5G compatible for speedy downloads and streaming

Who is this for?

The Galaxy S23 Ultra is a beast for power users who need their phone to be a sketchbook, a camera, and a productivity workhorse in one. It’s ideal for creatives, professionals who like to scribble notes with the S Pen, or anyone who wants that massive screen for Netflix marathons or detailed editing. Its camera system genuinely stands out for high-resolution photography and versatility, while the large, crisp display is purpose-built for multitaskers and mobile media fanatics. If you’re after a more pocketable device, the Galaxy S23 or S23+ might suit you better, but for those chasing flagship features, this is still one of the most complete Android packages you can find—refurbished or otherwise.

Pros & Cons:

Pros	Cons
200MP camera for ultra-detailed shots and crisp zoom.	Large size may be unwieldy for smaller hands or pockets.
S Pen support makes note-taking and sketching easy.	No microSD slot—expansion fans will miss it.
Vibrant, expansive QHD+ display with adaptive 120Hz refresh rate.	Premium build makes it a bit heavy—definitely chunky.
Built-in IP68 water and dust resistance.	Charging brick not included (in line with recent industry “progress”).
