It went really well. Transferring the data from my old phone to the S23 was easy, as was putting in the Sim card from my old phone. The S23 connected instantly to my Verizon network. It was just so easy when following your detailed instructions! I am delighted with it! I have already sung your praises to my friends so they can also buy from you!

I am pleased to report that the phone arrived in perfect condition. Although I initially had some trouble activating the SIM card, I contacted Metro support, and they were incredibly helpful in completing the setup process for me.

Very excellent phone. I was hesitant to purchase a refurbished phone after having difficulties in the past with subpar products. This phone is an incredible proof of quality. I got a Galaxy S23 in Excellent condition and genuinely I would believe this was a new phone. Absolutely flawless condition. No marks, scratches, dents, or any sign of use. Amazing price for the phone. Super fast shipping. I am going to continue to use Backmarket in the future and will recommend them to anyone who will listen. 10/10.

Everything is going well. Easily transferred service and data. My family has received a few refurbished phones from Back Market and we have zero complaints. We will be happy to use Back Market in the future.

Exchanged a Samsung Galaxy S9 for a Samsung Galaxy S23. I came across Back Market in an article and after checking them and many other refurbished electronics suppliers I felt completely comfortable to take a chance. The order process itself was very easy and product shipped/arrived as promised. The staff picks were helpful in deciding on what to get as well. I had no problem setting up the phone myself thru my current carrier Verizon. ALL data transferred successfully. I took it in just to make sure I did everything correctly and without knowing it was refurbish, even they said the phone looked and operated as New. I would definitely use Black Market again . (I ordered an Excellent level which was similar price to Good condition at the time.)

Phone came in pretty quickly and it works perfectly fine the condition it came was really good. First time buying refurbished phone was skeptical but relieved with how well it works. Would give five stars but i have one small issue . When my volume is high i hear a tiny static noise like vibrations and cant seem to fix it but you can barely hear it. Other than works really i would only give 4.5 stars.

The Galaxy S23 is Samsung’s 2023 flagship, and while it’s now a generation behind the latest, it still packs plenty of flagship-worthy features. With its handy size, advanced camera system, and fast processor, this phone keeps up with the pace of modern life—no wild claims, just reliable performance for people who want a stylish, powerful Android with a proven track record.

Key features:

Release Date: February 2023
Display: 6.1-inch Dynamic AMOLED 2X, FHD+ (2340 x 1080 px), 120Hz refresh rate
Processor: Qualcomm Snapdragon 8 Gen 2 for Galaxy
Camera: Triple rear cameras: 50MP (wide) + 12MP (ultra-wide) + 10MP (telephoto), 12MP front camera
Operating System: Ships with Android 13 (One UI 5.1)
Build: Gorilla Glass Victus 2 (front & back), Armor Aluminum frame
Connectivity: 5G compatible, Wi-Fi 6E support

Who is this for?

The Galaxy S23 is a solid pick for professionals and students who want premium features—like a fast display, excellent cameras, and dependable build quality—without chasing the absolutely latest tech. It’s smaller and easier to use one-handed than larger models like the S23 Ultra, while offering a better balance of usability and performance than older Samsung flagships. If you’re after a practical, durable, and modern Android, this one’s for you.

Pros & Cons: Pros Cons Compact flagship build—easy to use with one hand. No expandable storage—microSD slot is nowhere to be found (again). Fast, smooth display with 120Hz refresh rate. Camera zoom isn’t as advanced as the Ultra models. Gorilla Glass Victus 2 for improved durability. Incremental updates over the S22—expect evolution, not revolution.
Why refurbished?

Choosing a refurbished Galaxy S23 supports tech that’s built to last and the planet, too—less waste, same modern features. Every pre-owned device on Back Market goes through rigorous testing and quality checks for peace of mind. Learn more about our quality standards.
