Verified purchaseReviewed 12/03/2026, United Kingdom.
5/5Excellent 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!

5/5Good 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 I intend to keep my phone for a couple of years and then buy a reconditioned S25 equivalent when that model has been superseded by newer models and is therefore very good value buying a reconditioned one.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.

4.4/5I’m really happy with my purchase. A big well done to the seller — they did an amazing job, and also well done to Back Market for providing such a great service. The phone arrived looking great and it works perfectly. The performance is excellent, and overall it feels like a really good device. One small thing I noticed is that when I shake the phone, there is a slight rattling sound. I believe this is quite common with phones because of the camera components, so it doesn’t worry me. Apart from that, everything is fantastic. The condition is very good, it works smoothly, and I’m really pleased with it. Amazing value for money, and I would definitely recommend buying from this seller and Back Market! Much love from me - Adam ❤️

3.9/5Device arrived quickly no issues with delivery, and phone seems to work properly. However it is very scratched. I did buy the 'fair' condition which can have "micro-scratches" but there are so many scratches and some of them are quite large, you can see a chunk of the screen with weird colours/distortion because of this (similar to when the screen is dirty). I have seen friends/family order 'fair' phones before and they had some small scratches but nothing like this. I have contacted support so will update on what they say, and plan to give the phone a try for a week to see if I get used to it but probably return it afterwards. The phone also have some marks on the side which I don't mind, I have photographed them for information.

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
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. |
