SAMSUNG Galaxy S23 Ultra 5G Factory Unlocked 512GB - Phantom Black (Renewed)

I’ve been using my Samsung Galaxy S23 Ultra for six months now, and it’s been absolutely worth every penny. Its sleek matte‐finish design feels premium without being too bulky, and the massive 6.8-inch Dynamic AMOLED 2X display with a 120 Hz refresh rate looks stunning and scrolls super smoothly, even out in bright sunlight. Under the hood, the Snapdragon 8 Gen 2 powers through everything multitasking, gaming, you name it without a single hiccup. The camera setup, led by a 200 MP main sensor, delivers crisp, detailed photos in daylight and surprisingly clean low-light shots, while the 10× optical zoom and 100× Space Zoom actually capture usable far-away details. Battery life easily carries me through a full day of mixed use, and when I do need a charge, the 45 W fast charger gets me back to 100 % in under an hour, plus reverse wireless charging has saved my earbuds more times than I can count. One UI keeps getting better with handy features like split-screen multitasking, and S Pen support is a game-changer for quick notes and sketches. Six months in, it still feels as fast, reliable, and feature-packed as day one, making it a flagship that fully justifies its price.

I was a little hesitant about buying renewed, but this S23 Ultra looks and performs just like a brand-new phone. Not a single scratch, battery life is excellent, and everything works perfectly right out of the box.The screen is stunning—bright, sharp, and smooth. The 512GB storage is more than enough for apps, photos, and videos. Performance is lightning fast, and multitasking feels effortless. The cameras are absolutely top tier, with incredible detail and clarity, especially in low light.It even came well-packaged with a charging cable, and setup was quick and easy. Honestly, I can’t tell this apart from new, and the savings make it even better. Highly recommend for anyone who wants a premium phone without the premium price tag.

Great phone! It's not the newest version but is a significant upgrade from my, still fully functional, S10. A great upgrade without spending a thousand dollars.

I purchased this Galaxy S23 Ultra from Big Box LLC on June 17, 2025, based on the listing clearly stating the device was “Factory Unlocked.” That turned out to be false.📅 Timeline of What Happened:June 17 – Order placed and shipped same day.June 18 – Inserted SIM and discovered the phone was locked to AT&T.June 19–20 – AT&T confirmed the device was under an unpaid installment plan and ineligible for unlocking.The seller provided an incorrect unlock code, which they later admitted was missing a digit.After multiple failed attempts, the device became MCK locked — a high-level lock that makes the phone completely unusable.I spent over a week trying to get a valid unlock or MCK code from the seller. They kept stalling.June 28 – Seller admitted they couldn’t obtain the MCK code and instructed me to return the phone.⚠️ Why This Matters:A factory unlocked phone should never require an unlock code — and certainly not end up MCK locked.I made 8 trips between T-Mobile and AT&T trying to resolve this.I lost 15+ hours of professional time, and the phone was bricked because of the seller’s incorrect information.After all of this, the only resolution was to return the phone — which I did under protest, with the entire incident documented.I’m grateful that Amazon support has been helpful and professional, but buyers should be extremely cautious with this seller. A device tied to a financing plan should never be sold as “factory unlocked.”If your time and peace of mind are valuable, look elsewhere.

Great phone in great condition. A month later, I am so pleased with my purchase!

This is not my idea of excellent condition. At best, it is good. (1) The screen has some kind of a mark on the left upper side. Not exactly a scratch, but like a chemical burn. I am happy that putting on a screen protector now makes it indistinguishable. (2) there are visible signs of glue at the back of the phone around the camera lenses. (3) Bottom left edge of the phone shows signs that it was impacted (most likely it fell). (4) Left side bezel, not well fitted, a ridge can be detected when you run your hands over it.Having said all of that, the phone seems very much to be in good working condition, no issues there.

The screens shatter really easily. Broke in my pocket the first day with nothing else in my pocket and the screen facing towards my skin. I gave it 2 stars, the phone comes with a screen protector 😆

Love this great item, best purchased.
