I ordered a T-Mobile phone and you sent me a locked AT&T phone. I sent it back 7 days ago and you're telling me that the seller hasn't received it yet and that it is supposed to arrive tommorow. This was a present for my wife and it's going to be at least another week before she can get a replacement. This amount of time is just unacceptable.

I was referred to Back Market by a friend but was still a little skeptical but after finally making my purchase, I'm extremely satisfied. Phone came in basically brand new condition with manufacturers protective tape still on it. I thought there would be a "catch" to the deal but I honestly can't pick on anything negative. Will surely be looking here first for any future phones and devices. Keep it up!

Purchased two in "Excellent Condition", unfortunately only one is. The other has marks all over top and bottom edges as well the rims around the cameras like it's been slid around on tables before. A fairly deep scratch in the center of the screen. Verified "Excellent Condition " was selected and ordered before leaving a review.

Ordered Samsung Galaxy S23 Ultra 512GB Green Excellent condition for $451.90 with tax on May 28 and delivered next day. Awesome right? No! They sent me the normal s23 not the ultra! They are offering full refund but not honor to send me the model I purchased for the same price. Don't waste time playing these games, disappointed never will shop with back market.

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:

Release Date: February 2023
Display: 6.8-inch QHD+ Dynamic AMOLED 2X, 120Hz refresh rate
Processor: Qualcomm Snapdragon 8 Gen 2 for Galaxy
Camera: Quad rear cameras: 200MP wide, 12MP ultra-wide, 10MP 3x telephoto, 10MP 10x periscope telephoto
Stylus: Integrated S Pen for note-taking, sketching, and remote control
Build: Armor Aluminum frame, Gorilla Glass Victus 2 front and back
Connectivity: 5G and Wi-Fi 6E compatible
Operating System: Ships with Android 13 (One UI 5.1)

Who is this for?

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.
Why refurbished?

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.
