Excellent, perfect physical condition, easy switch over from old phone and to Google watch. Will most definitely use Black Market again. Shipping was excellent and send back of old phone was super easy with the provided packaging. ❤️

Almost no signs of wear. The body may have very light micro-scratches. For items with screens, the screen will have no scratches.

The phone arrived later than I was expecting, but it was in perfect condition. There were no marks on it whatsoever, and if it hadn't been in a regular box I would not have known it was not brand new. Good price too. I would definitely do business with Back Market again and would recommend it to others.

Tons of scratches on the screen with 2-3 deeper ones, but the phone works as intended so I don't mind. A description of the cosmetic damage would have been nice. But you get what you pay for and a used phone is exactly what I wanted. Good price, decent condition as expected.

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.
