It’s amazing! I love the color the screen was perfect and clean as it should’ve been! The black outline complements the color so well. It works smooth and so far no problems! I loved switching to this phone from the IPhone 15 Pro Max, lol Samsung is way better.

This phone is great. It came in perfect condition with zero scratches or defects. It has the best camera I've ever seen. I bought a small telescope to look at the moon and ended up returning it because I can see a lot more detail and better quality with this phone. It'll even zoom in on stars which is really cool.

The device is excellent so far; everything works as it should. It looks like the screen was replaced, but it's a used device, not a deal breaker for me. The device is clean and also came with a free phone case for an S22 Ultra. I love it.

this phone is absolutely gorgeous. no scratches or scuffs anywhere on it. fast performance and it works super well for the price I paid for it. great battery life and I'm totally digging the yellow color. I'm convinced this thing is practically brand new. I did end up returning it only because I wanted the s25 ultra for it's better AI features. I would recommend this phone though

My phone arrived within the promised time with updates along the way ..phone is in excellent condition as I ordered it ,switch over was pretty simple with the help of an email from black market and smart switch from Samsung, screen is perfect, outside cover no visible scratches hardly even know it wasn't brand new to be honest..so far so good as performance and functionality. Big upgrade for me from another Samsung A32..so some features I will have to learn ..I will update if I notice any issues in the future, purchase from the website was smooth and easy ..will be doing the next upgrade from the black market again ..Thank you for saving me hundreds of dollars on an excellent phone upgrade

I am loving my Samsung Galaxy Ultra 24. Transferring the data from my old phone was a breeze. Installed the updates with no problems. The phone was shipped fast. This is my third phone I have purchased from Back Market and will continue to recommend this company. Refurbished phones save me a lot of money!

The Galaxy S24 Ultra, released in January 2024, stands out in Samsung’s lineup as a flagship option focused on raw performance and cutting-edge features. Just one generation old in 2025, this device blends a robust build with a feature-packed camera—which is saying something, given the yearly “Ultra” expectations. If you want the latest bells and whistles that actually feel overdue, this is a solid contender.

Key features:

Release Date: January 2024
Display: 6.8-inch QHD+ Dynamic AMOLED 2X, 120Hz refresh rate
Processor: Qualcomm Snapdragon 8 Gen 3 (for most global models)
Camera: Quad rear camera: 200MP wide, 12MP ultra-wide, 50MP periscope telephoto, 10MP telephoto
Operating System: Ships with Android 14
Build Quality: Armor Aluminum frame, Gorilla Glass Armor front and back
Connectivity: Wi-Fi 7, Bluetooth 5.3, 5G compatible
S Pen support

Who is this for?

The Galaxy S24 Ultra is engineered for power users: professionals managing projects, photographers needing versatile lens options, and anyone who wants a stylus-equipped phone that acts like a digital notepad. Its large size and camera array don’t make it the most pocket-friendly device. If you’d rather have a smaller form factor, the regular S24 or S24+ might be easier to handle.

Pros & Cons: Pros Cons Versatile quad-camera system excels in nearly any setting. Large size makes one-handed use tricky for most people. S Pen support for note-taking and creative tasks. No expandable storage — what you get is what you get. Top-tier performance thanks to the Snapdragon 8 Gen 3. Bloatware could be a drawback for purists who prefer clean Android. Wi-Fi 7 support brings future-ready connectivity. Heavier than previous Galaxy Ultra models, so it’s not the world’s most subtle slab.
Why refurbished?

Choosing a refurbished Galaxy S24 Ultra on Back Market helps reduce electronic waste while still offering standout specifications. Each pre-owned device is tested and restored following strict guidelines—so you’re not locked out of a flagship experience. Learn more about our quality standards.
