The phone was delivered on time and in "excellent" condition. I transferred data from my old phone, the SIM card, and BINGO, I was up and running. This was not my first rodeo with Back Market, and every time it has been a great experience at a great price. I have been recommending Back Market to everyone I know who is looking to upgrade a device.

Arrived fast and is in excellent condition as advertised. Have used it for now a few weeks and have had zero issues. Am happy with this new phone which was an upgrade from a Samsung Galaxy S9 that was also refurbished.

I have had a Samsung Galaxy s10+ for about 4 years, which I also got off Backmarket. I wanted to upgrade because it was starting to show signs of failure on the OLED display. I chose the Samsung Galaxy s24 in excellent condition. the phone has basically 0 signs of wear, all I found was the teeniest tiniest chip on the metal around one of the cameras. Other than that it's flawless. The battery also seems to be in good condition which is one of the things that matters most to me in a phone. it's probably not as good as a fresh phone but it still lasts over a day and is noticeably better than my old phone. I never thought of my s10+ as slow, even at the time if replacing it, but now after upgrading to the s24 it feels laggy. The s24 is a smooth experience. I was considering doing an s25 but I went s24 to save some money and I don't have any regrets. I'm not even sure what else the s25 offers that the s24 doesn't. I imagine its a very similar experience. But yeah, I think purchasing brand new is a waste, backmarket has done me good twice now.

I was skeptical of doing a refurbished phone. Ordered it, it came within 3 days or so. Opened it, examined it. The phone had a little dent in the top right side of the phone, but everything else was looking New. it was smaller than what I was thinking the size might be, but I'm in love with this phone. Battery so far is working and lasting as long as I need it to (problem with my A35 5g phone). I haven't had any problems with it. So glad I tried this app.

Another great quality purchase from Back Market. I upgraded from a S20FE and it all when pretty good. The S24 is a great upgrade and the smaller size is a super advantage for me.

This my third Back Market purchase and it never disappoints. I could not be more pleased with the quality and condition of my Galaxy S24 - like brand new. I took advantage of the Visible-Back Market offer and am very happy with the results.

My Galaxy S24 is just like new and at a fraction of the cost of a new phone. It arrived on time, and Black Market made it so easy for me to transfer everything from my ancient android to my new phone. I am 100% happy.

The Samsung Galaxy S24 is the 2024 flagship from Samsung, bringing routine updates to a familiar, compact design. As of 2025, the Galaxy S24 is one generation old, but remains current thanks to its efficient chipset and versatile camera system. While the upgrades might be incremental, it still covers all the essential bases for those who appreciate a streamlined, straightforward Android experience.

Key features:

Release Date: January 2024
Display: 6.2-inch Dynamic AMOLED 2X, FHD+ (2340 x 1080 px), 120Hz refresh rate
Processor: Snapdragon 8 Gen 3 (USA) / Exynos 2400 (global)
Camera: Triple rear cameras (50MP main, 12MP ultrawide, 10MP telephoto with 3x optical zoom)
Operating System: Ships with Android 14 and Samsung One UI 6.1
Build Quality: Armor aluminum frame with Gorilla Glass Victus 2 (front and back)
Connectivity: 5G compatible, Wi-Fi 6E, Bluetooth 5.3, USB Type-C

Who is this for?

The Galaxy S24 is best for Android fans seeking a compact, no-fuss flagship with the latest connectivity and camera basics. Professionals who want efficient performance without carrying a massive phone will appreciate its manageable size. Compared to the S23, you get subtle performance and AI tweaks, but if you’re holding onto an older Galaxy, this generation brings meaningful improvements. For camera enthusiasts, the triple-lens setup hits the sweet spot for everyday versatility—but the S24 Ultra remains the go-to for those seeking zoom power or S Pen integration.

Pros & Cons: Pros Cons Compact and lightweight design, easy for one-handed use. No expandable storage—microSD is still missing. Sharp 120Hz AMOLED display for vibrant visuals. Camera hardware is solid, but lacks pro-level zoom found on S24 Ultra. Durable build with improved Gorilla Glass Victus 2. Only minor upgrades vs. Galaxy S23. Latest Android OS with Samsung’s extended update promise. No S Pen support (for that, see the Ultra).
Why refurbished?

Choosing a refurbished Galaxy S24 means fewer electronics in landfills and more tech in your pocket. At Back Market, every pre-owned device is carefully tested for quality, so you don’t have to worry about what “refurbished” really means. Learn more about our quality standards.
