The ultimate Galaxy experience. The Samsung Galaxy S23 Ultra brings together exceptional performance, a professional-grade camera system, and the iconic built-in S Pen. Powered by the Snapdragon 8 Gen 2 for Galaxy processor, it's designed for creators, professionals, and power users who demand the very best.
Why the Galaxy S23 Ultra Stands Out:
Built-in S Pen: Write naturally, sketch ideas, annotate documents, and enjoy precision control directly from your phone without carrying extra accessories.
Legendary 200MP Camera System: Capture extraordinary detail with the 200MP main camera, supported by ultrawide, 3x telephoto, and 10x periscope zoom lenses for stunning photography at any distance.
Dynamic AMOLED 2X Display: The expansive 6.8-inch QHD+ display offers adaptive 1-120Hz refresh rates, exceptional brightness, and vivid colours for immersive viewing.
Elite Snapdragon Performance: Equipped with the Snapdragon 8 Gen 2 for Galaxy and up to 12GB of RAM, the S23 Ultra delivers lightning-fast gaming, multitasking, and productivity.
All-Day Power & Productivity: A large 5,000mAh battery, advanced multitasking features, Samsung DeX support, and premium build quality make this a true flagship device.

Conditions Explained
Excellent
Immaculate condition. A near-perfect device with only the faintest micro-scratches on the body/edges, invisible from 20cm away. The screen is clear and pristine, offering a premium feel for less.
Good
Daily reliability. Shows light signs of use, such as minor scuffs or shallow scratches on the casing/screen. A highly cost-effective choice that looks great when paired with one of our protective cases.
Fair
Budget champion. Noticeable cosmetic wear, including scratches or small dents. While it looks "well-loved," the internal technology is 100% certified and fully functional. Best for the savvy saver.
All grades are backed by our 12-month warranty.

Better than refurbished!
I was nervous about buying a 'used' iPhone, but Nefix totally changed my mind. The device arrived in 'Premium' condition without a single scratch. It looks and feels brand new, but at a fraction of the retail price. I'll never buy a new phone again!

Literally next-day delivery
I dropped my old phone and needed a replacement fast. I ordered a Pixel before 2PM and it was at my door the very next morning. The 12-month warranty included in the price gave me the extra peace of mind I needed to hit 'Buy'.

Incredible battery performance
My biggest worry with used tech is always the battery life. I was thrilled to find my Galaxy S23 arrived with 98% battery health. It lasts me all day through heavy work use. This company clearly takes their 70-point diagnostic check seriously.

Sustainable and smart
Great experience from start to finish. I love that I could get a high-spec device while also doing my part for the planet by choosing refurbished. The packaging was eco-friendly, and the shipping was lightning-fast. Highly recommend Nefix for anyone shopping smart.
