    • Samsung Galaxy ultra s23
Service provider: Unlocked Color: Phantom Black Size: 256GB
I usually never leave reviews but I had to for this phone. This phone is the best purchase of a phone I have made here on Amazon. The phone came in perfect condition no scratches, no problems it even came with a black out screen. I couldn't have asked for a better phone purchase than the one I got. The screen is nice and big, it's very sturdy and durable. And the connectivity was very easy. Thank you so much for my phone. ... show more

    • Good enough
Service provider: Unlocked Color: Phantom Black Size: 256GB
Came in, some scratches on the back plate as expected for being used. Screen was not affected. Works great would get renewed again.

    • S23 Ultra over the newer models, totally worth it.
Phone is great. No imperfections, scratches, or defects. Color is a little pinker than it looked online but all is good, most have cases anyway. I bought this one for the camera and it delivers. Camera is as good as the newer models so if you're looking to save some money, get the 23. Storage size was accurate as well. System works like new. Transferring from my old phone was an absolute breeze. Charger works well. Battery life is okay, not amazing. If I didn't know better, I'd think it's a brand new phone. I came from a Note 20 ultra, and I think this s pen is actually better and smoother. I only wish the screen was flat as it's hard to find protectors that fit, but otherwise I love my new (older) phone! ... show more

    • ⭐️⭐️⭐️⭐️⭐️ Excellent condition, great performance, and plenty of storage
I was honestly surprised by how good the condition was for a renewed phone. The S23 Ultra arrived clean, fully functional, and without any noticeable scratches on the screen or back. Battery health says good and the phone performs just as fast as a brand new model. The cameras are sharp, the screen is bright and smooth, and the overall performance is great for multitasking, gaming, and everyday use. I bought the 1TB version and the extra storage has been a huge benefit. There is plenty of space for videos, photos, apps, and files without worrying about filling it up. Everything set up quickly and the phone has been reliable with no glitches or issues so far. If you want the S23 Ultra but do not want to pay full price, the renewed version is a great value. Mine feels almost like new and the 1TB storage option makes it even better for long term use. ... show more

    • It's not bad for saving a few dollars.
Service provider: Unlocked Color: Green Size: 256GB
The phone works, but it has scratches and scuffs on the corners. The pen doesn't work; it's stuck inside the phone and the only way to remove it is with a pin. The battery, as the description says, is at 80%, but with daily use it lasts around 9-10 hours.
