The phone arrived in excellent condition. Setup was fast, and the SIM configuration was straightforward. The screen and back are flawless. The only minor wear I noticed were some superfine scratches on the top and bottom of the device.

Device is working great and as intended. The signs of use are CLEAR on the outside of the case as many of the metal pieces have missing paint. A case covers that up fine. I wish there was a better means of judging what defines used or great condition.

Transfer took a long time at the Verizon store, probably due to the age of my old phone. So far I'm loving the S23 Ultra. It's in perfect condition, externally and operationally. Couldn't be happier.

The Samsung Galaxy S23 Ultra sits at the top of Samsung’s smartphone lineup, bringing pro-level tools to everyday users. Released in February 2023, it’s only one generation old as of 2025, which means most of its hardware is still very much in the “cutting edge” club. Key highlights include its large display, distinctively integrated S Pen, and a camera system that raises the bar for mobile zoom and detail.
Key features:The Galaxy S23 Ultra is made for multitaskers, productivity pros, and anyone who needs a big screen for creative work or detailed viewing. If you’ve outgrown “good enough” smartphone cameras, the S23 Ultra’s quartet of lenses, especially that 200MP main sensor, lets you get closer or see more without a lot of extra gear. Compared to the S24 Ultra, you’re not missing much in terms of day-to-day use, but you’ll save yourself the shiny-new-tax – and the S23 Ultra still outclasses most other Android phones on the market. If you just want a basic, pocketable phone, this probably isn’t your match.
Pros & Cons: Pros Cons High-resolution 200MP camera for detailed photos. Large and heavy—not for small hands or tight pockets. Integrated S Pen for precise input and productivity features. Pricey repairs if dropped—gargantuan screens tend to crack rather than bounce. Smooth 120Hz display makes gaming and scrolling feel fluid. No microSD slot—cloud storage fans won’t mind, but file hoarders might. Top-tier performance from its Snapdragon 8 Gen 2 chip. Overkill for casual users—if you just check email, the Ultra is probably Ultra-unnecessary.Choosing a refurbished Samsung Galaxy S23 Ultra means less e-waste and one less device destined for the landfill. At Back Market, every pre-owned device goes through rigorous testing to ensure it’s up to our standards—no shortcuts. If you want to see what that means, read about our quality standards here.
