    • GREAT PHONE!!!
Service provider: T-Mobile Color: Green Size: 256GB
Great phone! Works better than my last device. The phone is quick, has lightning fast responses with noticably higher quality visuals and camera quality. The phone is inside of a water proof case which ensures and maintains long-term durability. The unit connects to Internet flawlessly. The color is perfect. The phone may heat up significantly but it does not affect overall performance. The OLED screen may be a replacement because there are slightly trimmed edges on all corners but I am not complaining. ... show more

    • Stay FAR AWAY
Service provider: Unlocked Color: Phantom Black Size: 256GB
I would give this seller less than zero stars if I could. When I first received the renewed Samsung S23, it appeared to be in good working condition. However, just under 3 months later, the phone began randomly shutting off and restarting on its own. At first it would turn back on, but shortly after that it froze completely. I powered it off, and it never booted up again. It became stuck in an endless boot loop. This phone was very well cared for. It was always kept in a sturdy protective case, had a screen protector from day one, and was never dropped in water or exposed to moisture. I took the phone to a Samsung technician to see if it could be repaired. After opening the device, they found signs of internal water damage. The technician also discovered stripped screws that could literally be lifted out with a magnet instead of being unscrewed properly, and two antenna components were completely missing. The phone could not be repaired. Of course, this happened just days after the 90-day warranty expired, so the seller refused to replace or refund the device. In my opinion, selling poorly refurbished phones that fail immediately after the warranty period is unacceptable. I will never buy a renewed phone from this seller again. For comparison, we’ve purchased multiple phones through Back Market with their 1-year warranty, and those devices have lasted for years without issues. ... show more

Arrived in 3 days. Looks new, no marks at all, no signs of use at all. It works. I only use it mostly to text, make a few calls, and locate my family. It would not accept a Walgreens SIM until I reset it to factory settings. Then it was great.

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

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
