⭐⭐⭐⭐⭐ Excellent Flagship Value – Feels Premium Without Paying Full Price I purchased the Samsung Galaxy S23 Ultra (Renewed), 256GB, US Version, Unlocked and have been genuinely impressed. If you're looking for a premium flagship phone without spending the price of a brand-new model, this is an excellent choice. The phone arrived in great condition with little to no visible wear. It looked almost new, and the screen was free of noticeable scratches. Setup was quick and easy, and since it's the unlocked US version, activation with my carrier was straightforward. Performance has been outstanding. The Snapdragon processor handles everything smoothly, from everyday tasks like browsing and social media to gaming and multitasking. Apps open instantly, and I haven't experienced any lag or freezing. The display is one of the biggest highlights. Samsung's AMOLED screen is incredibly bright, sharp, and colorful, making videos, photos, and games look amazing. The 120Hz refresh rate makes scrolling and navigation feel incredibly fluid. The camera system is exceptional. Photos come out crisp with excellent detail, even in low light. The zoom capabilities are impressive, and the video quality is among the best available on a smartphone. Whether you're taking family pictures or scenic shots, the results are consistently excellent. Battery life easily lasts a full day with moderate to heavy use, and fast charging gets the phone back up quickly when needed. The included S Pen is another feature I didn't realize I'd use so often—it's great for taking notes, editing photos, and navigating with precision. Since this is a renewed device, I was a little hesitant at first, but my experience has been very positive. The phone performs like a flagship should while costing significantly less than buying new. Pros: Premium design and build quality Gorgeous 120Hz AMOLED display Outstanding cameras with incredible zoom Fast, smooth performance Excellent battery life Useful built-in S Pen Great value as a renewed device Cons: May not include the original Samsung packaging or accessories. Battery health can vary slightly depending on the renewed unit, though mine has performed very well. Overall, I highly recommend this renewed Galaxy S23 Ultra to anyone who wants flagship performance and features at a much more affordable price. It delivers an outstanding experience and is one of the best values you can find in a premium smartphone. ... show more

Awsome phone
Service provider: Unlocked Color: Phantom Black Size: 256GB
Feels Premium Right out of the box, you can tell this phone is built like a tank. The glass and metal feel sleek, solid, and high-end in your hand. Awesome Screen and Speed The display is huge, bright, and super sharp. Everything loads instantly, apps never lag, and playing games on it is super smooth. The Cameras Are Insane The photos come out crisp every single time, even at night. The zoom is the real party trick though—you can take clear pictures of things impossibly far away. Battery Lasts All Day I easily get through a full day of heavy streaming, photos, and browsing without stressing about finding a charger before bedtime. ... show more

Buyer beware
Service provider: Unlocked Color: Phantom Black Size: 256GB
Do not buy from ecobuyphone. I had ordered a "excellent" condition Samsung s23 ultra refurbished. Recieved correct model but phone was a previously damaged and repaired. When i recieved phone, i noticed lower right camera had damage & rattled when shook but phone appeared to function properly. Few weeks of using it and screen cracked from normal use (no drops & has been in otterbox since i activated it with liquid glass as well) Was only cosmetic and small so continued to use 2 months later i had it in pocket and put keys in pocket, that causes it crack all way across in a different area from first crack. Went to ubreakifix to get a new screen. The screen completely disintegrated when removing. They called me and told me the screen was not an owm samsung & it was very thin. Apparantly this is a common problem for a cheap repair to get rid of phone. I was still ok with that & the 330$ replacement screen until they called back and alerted me that they had a new screen on it and everything was fixed and working great but tue phone couldnt be released because of a previois repair ticket being opened in this phone. Samsung wont allow them to trplace or repair until the previous ticket is resolved. Long story short, i now have a 500$ paperweight with no screen as they had to remove the newly installed screen before returning phone. The old was was too damaged to reinstall Buyer beware ... show more

Arrived in Condition Advertised.

Arrived safe and sound. Phone was in expected condition. Only complaint I have is the phone refuses to allow transfer of files to my PC with included cable or several other cables I have. Of course, this would not seem to be the fault of the seller, but that of Samsung. Otherwise I am enjoying the phone. ... show more

I waited about a week before posting to get a feel for the device and ensure everything works well. Before the full review I want to note that I posted an unboxing video. The phone arrived in bubble wrap with a generic 10 watt charger included. Do not use that charger — plan to purchase a minimum 45 watt charger and a high quality cord. Using the included charger may cause battery overheating, slow charging, and long term battery damage. Another concern was that when I plugged the phone in for its initial full charge, I received a water detection warning. I tested three of my S22 Ultra cables that have never had issues and got the same warning each time. I used a small cool fan briefly, stood the phone upright. Just be cautious and double check your charging port before use. The water detection warning has not returned once since that first day — the fix worked completely. The phone also did not come with a SIM card removal tool. If you don't have one, the back of an earring works surprisingly well as a backup — that's always been my go-to. Luckily I had my own tool for the SIM swap. (These are the reasons I couldn't give 5 stars. Had I not caught these issues — especially the charger — I would likely have been frustrated enough for 1 or 2 stars.) That said, this phone is amazing. I'm coming from the S22 Ultra so the UI was immediately familiar, with many similar features and an easy transition. The biggest improvement is the processor — App installation, gaming without lag, browsing, music from the internal speakers, all noticeably better across the board. Most notably for my usual activities, game downloads that took 2+ minutes on my S22 Ultra now complete in approximately 10 seconds on the S23 Ultra. The difference is genuinely dramatic. I transferred approximately 128GB of apps and data wirelessly from my S22 Ultra in about 40 minutes. A USB-C to C cable would have been faster, but after the water detection warning I didn't want to use a cord for that step. The 40 minutes was likely influenced by the transfer speed of the older S22 Ultra as the source device. After the transfer, everything was loaded exactly as it was on my previous phone — it connected to my WiFi without entering a password, and my Samsung biometrics remembered passwords for each app, making it seamless to use immediately. The battery does not overheat the way the S22 Ultra is well known to do, which was a major concern of mine going in. The condition was as described. There were two very small micro cracks near the edge, but after applying a screen protector they are completely invisible. If they ever become visible I'll simply use a liquid glass repair solution. After extensive research I'm not concerned about the screen integrity. The camera is phenomenal. I was always impressed with the S22 Ultra camera, but the increased resolution makes every shot noticeably more vivid. Photos look almost better than real life, with no extra steps needed — just point and shoot. The 512GB storage is more than I'll likely ever need, even with a heavy volume of photos, videos and apps. I don't see myself coming close to capacity. I spent considerable time deciding between the S23 and S24 Ultra. After thorough research the benefits of paying several hundred dollars more for a marginally better camera and minor improvements weren't justified. This phone represents an incredible upgrade at a very reasonable price. Edit: After using for about a month i wanted to note that the battery lasts for an extreme long time, the photos are absolutely incredible, the processing speed... is unmatched, I used to lag, or have apps crash, now everything is seemeless. This is just an amazing phone! ... show more

Phone is awesome, but mine was network locked to AT&T. Read review in full!
Service provider: Unlocked Color: Green Size: 512GB
It is almost identical to my last phone, the S22. I dropped the s22 and went ahead and bought this S23 Ultra. They replaced the screen on the S22 in 4 hours and it is excellent renewed. Instead of returning this s23 ultra I decided to keep it. This S23 Galaxy ultra should last many years. One issue I encountered was that the phone was locked to AT&T unlike what was advertised. I chose to use Unlockme mobile to unlock. Not recommended. It took 5 days and instead of charging me the initial 24 dollars that I paid at the beginning, at the very end they charged me $96.00 for the unlock code. A big scam. I found out that in my call to AT&T that they no longer give unlock codes and recommend to me to use Unlockme. I should have just returned the phone to Amazon. I didn't because I am confined to a nursing home and could not drop phone off at an Amazon drop off location. If phone is locked save $120 and just return it. ... show more

This was a miserable experience. I never bought a renewed phone before. I purchased a Samsung Galaxy 23 Ultra and the seller was Chubbies Tech I severely cracked the screen on my older phone and the screen replacement was pretty expensive. This slightly newer model offered a significant upgrade ( I had an S22 Ultra and the S23 Ultra was a big jump in improvements) So instead of sinking money into the screen, I could get a newer model and more memory than I had before. I was upgrading from 256GB to 512GB so this seemed like a great deal. Because the phone is older, it took hours to download what felt like a million updates and get the phone up to date. Then doing Samsung Smart Switch took a while too. So I had hours into this before I even tried to activate it with Xfinity Mobile. When I did finally get to that part, I entered the IMEI number Xfinity Mobile said "Your phone is compatible but may be locked to another carrier". At that point I was crushed, I already was behind and needed a working phone. I immediately messaged the seller through Amazon to find out what could be going on. They replied a few hours later only to say they were sorry and offer a refund or replacement. So now I would be looking at more days without a working phone . I would have to spend hours wiping the phone data, mailing it back and then more hours to install updates and switch everything again on a new device. I really didn't want to send it back if there was any way for it to work. After reading more on Xfinity's site I saw this "Some carriers will automatically unlock their customers' phones after a period of time. Some carriers will only unlock your phone if you ask them to." and there are unlock services out there as well. The unlock services do not seem to be doing anything any different than your carrier can do so I decided to call Xfinity Mobile and see if they could help. But I also have to wonder why these mobile phone resellers do not just truly unlock the phones with a service since this is their business. They seem fine to put the burden on whoever buys it to figure it out. Xfinity Mobile was able to successfully get the phone active after about an hour on the phone with them. So I am really glad I didn't just send it back. Who is to say the replacement would not be the same thing all over again?This was an education in renewed phones but if this was my business I would offer this guidance right away in a troubleshooting section or email before I would have someone send back a "locked" phone. My time is valuable so all this messing around with the phone still costs me. It took time away from work and caused stress. This does take away from the value of the renewed phone being cheaper than a brand new one. Overall though the device itself was mostly as expected. The color is nice. The screen was in good shape with no scratches. It had a plastic sticker cover on it. The only minor scratches I saw were around the camera lenses on the back and around the edge of the lens. (not like the listing says - no scratches from 12 inches away as per the "excellent" description) Not a deal breaker though either as the camera appears to work fine. See my photo. The battery arrived not charged and at about 12% which was not that big of a deal. It charged fast and has held a charge. So as far as the device itself goes, it is a good device and matches the listing. The reason for the 3 stars is that as I mentioned earlier, this was not a good deal considering all the extra time and energy it took to get it working and I almost sent it back too because of the response from the seller! That would have been way worse. ... show more
