Good value. I ordered a good condition phone and very happy with the condition of the phone I received. Very fast shipping. I only purchase reconditioned phones and have done so for many years. Back Market are my go to supplier and have always been impressed with both the phones and purchasing experience. In my case I usually by Samsung S series Android phones and typically buy a model that is two models down from the latest model. So I purchased a month ago a Samsung S23+ 256GB good condition and the latest model on sale is the S25. The saving of buying an older model and one that is reconditioned is considerable and is something that I will continue to do in the future. I intend to keep my phone for a couple of years and then buy a reconditioned S25 equivalent when that model has been superseded by newer models and is therefore very good value buying a reconditioned one. If you trade in your old phone you can get an even better price as a result.

Excellent condition. I did not realise I selected "fair" condition until after I purchased. However, the phone is immaculate and looks brand new. No marks, scratches, dents. I was pleasantly surprised. The battery life is excellent lasts more than a day. This is my first purchase from Back Market and will not be the last. I'll definitely be upgrading through them in the future instead of paying an insane amount for a new phone. No brainer! Delivery was super fast and the communication was great. I would highly recommend. Thank you!

I recently purchased a refurbished Samsung S23 Plus and I couldn’t be happier with my experience. The phone is in excellent condition—honestly, it looks and feels just like new. The delivery was very fast, and I really appreciated the regular updates at every stage of the order process, which kept me well informed throughout. Customer service was outstanding—helpful, responsive, and professional. Overall, I am extremely satisfied and would genuinely recommend this company to anyone looking for high-quality refurbished devices.

Had a refurbished s21 5g which was a step up from my Motorola g22. The s21 was terrible on battery life and got pretty warm doing anything. Not to mention it was out of security updates. Went for refurbished as I didn't want a really expensive new phone. Opted for top battery. It's night and day with my s21 5g. The more efficient snapdragon chip is much better for the battery and It doesn't get warm running tasks.

Refurbished Galaxy S24+ arrived quickly and was in excellent condition as sold. I traded in my old S10 which I believe was a good offer. If I hadn't done this it probably would have just sat in a drawer for years so it is great that Back Market give you this opportunitu. Wpuld definitely purchase again in the future.

The Galaxy S23+ sits just one generation behind the current flagship as of 2025, carrying forward much of what makes Samsung’s S Series shine. You’ll find a bright and spacious 6.6-inch display, powerful hardware, and a photography setup that delivers, all inside a sturdy glass and metal frame. It’s a choice that fits right in for those who value modern performance—without insisting on the very newest number on the box.

Key features:

Release Date: February 2023
Display: 6.6-inch Dynamic AMOLED 2X, FHD+ (2340x1080) with 120Hz refresh rate
Processor: Qualcomm Snapdragon 8 Gen 2 for Galaxy
Camera: Triple rear camera: 50MP wide + 10MP telephoto + 12MP ultra-wide, with 8K video recording
Build: Gorilla Glass Victus 2 front and back, Armour Aluminium frame
Operating System: Ships with Android 13 and Samsung One UI
Connectivity: 5G ready, Bluetooth 5.3, Wi-Fi 6E support
Other Features: IP68 water and dust resistance, ultrasonic fingerprint sensor

Who is this for?

The Galaxy S23+ is spot on for busy professionals, content creators, and anyone after a reliable, large-screen device for work, video calls, and weekend streaming marathons. If you’re upgrading from an older S Series (think S20 or S21), you’ll notice a clear jump in speed and camera quality. While not quite as compact as the regular S23, it gives you that extra screen space for productivity—without crossing into super-sized Ultra territory.

Pros & Cons:

Pros	Cons
Vibrant, sharp 120Hz display for smooth scrolling and video.	No built-in stylus—note-takers should check the S23 Ultra.
Strong triple camera setup for photography and 8K video.	No microSD slot means cloud storage fans will feel most at home.
Premium materials and IP68 rating.	Larger frame may be less pocket-friendly for some.
Latest Wi-Fi 6E for future-proof connectivity.	No major design change from the S22+—it’s familiar, not flashy.

Why refurbished?

Choosing a refurbished Galaxy S23+ is a practical, eco-conscious choice. At Back Market, every pre-owned device goes through rigorous checks for quality and function, so you get peace of mind with your tech—without fuelling electronic waste. Learn more about our quality standards.
