4.8/5love 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.

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
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”). |
