    • Title: "Excellent quality for the price"
The renewed Samsung Galaxy S21+ 5G arrived in perfect condition, with an almost new appearance and working very fast. The screen looks sharp, the cameras take clear photos and the performance is smooth for apps and networks. The battery lasts me well during the day and the equipment came fully unlocked, ready to use. ... show more

    • Device may have significant functional defects and user security/privacy concerns.
The phone I received (after I had logged into my Google account and transferred personal data to the device); was found to have a 3rd party app still installed which CLAIMED OWNERSHIP OF THE PHONE. Uninstallation of the app, which said that it had administrative privileges and that anyone with access to the base program could view/alter content of the phone; was allowed, yet the app warned it may leave residual holes in the phones security. After deleting the app, I notified Amazon about this seller potentially selling devices which were not completely initialized and may still be under the control of the device's previous owner. Since I don't sell/send-off data storage devices which I have entered personal information into, I will not be opting to swap for another potentially more defective unit. It has now been discovered that this device drops connection from WiFi without notification nor any indication of connection loss- except that messages cannot be received over WiFi until the WiFi connection is disconnected/re-enabled or the phone is restarted: this seems to happen almost daily and will likely force me into an unlimited data phone plan, on account of needing reliable connection while at home- assuming it won't require the SIM card to be removed and reinserted due to a similar issue with cellular connectivity. Company declined to refund me anything, citing that the 50% refund I requested was "more than they would ever offer;" yet I believe they were reluctant to offer any partial refund, due to my notifying them that I threw them under the bus to Amazon's customer service. This is the type of device reseller who would shamelessly sell stolen property- because they can always offer a device swap if they're found out. They are unaccountable for tricking Amazon customers into trusting devices they were in charge of making safe/secure for the customer, yet they are wholly unaccountable to the potential damages which their negligence may allow. Due to this experience, my family will no longer trust Amazon's refurbished phone resellers, like we have in the past. ... show more

    • Fantastic phone in great condition 👏
After a disaster buying a S22 plus and having to return it due to its disastrous condition including a glass screen that had smudge marks every where that i wasn't able to remove and the frame had chipped pain all around it. And obviously that was a different seller. This S21 plus is in absolutely fantastic shape. Everything looks fantastic and the performance is amazing. I highly recommend this seller. ... show more

    • Sleek phone
I came from a Galaxy 10 Note + and I'm so glad I went for this version with the larger screen. You may have to tweak some settings to get the battery to last all day but it seems to be a nice upgrade from my last flagship Samsung, so far I'm impressed even though this one is a few years "old". I bought an unlocked version, which I highly recommend, but you may need to be somewhat tech savvy to get your carrier to "accept" them. I like the more sleek feel. I'm glad I got this larger 6.7" screen. Beautiful display, but it can be a resource hog! Takes great photos. ... show more

    • Excellent condition, unlocked, worked with a European SIM card
I needed an unlocked phone to use in Italy and Austria. I bought this S21+ along with an "Orange Holiday Europe" SIM card. The phone arrived in excellent condition, with no scratches or dents. The screen appeared to have been replaced. After setting it up, I tested it by installing SIM cards from AT&T and TELLO, both worked perfectly - it's definitely unlocked. Right before the trip, I installed the "Orange" SIM card with the phone powered down. Upon arrival in Italy I powered it up, and it immediately connected to the local service. We used Google Maps to get from the airport to our hotel some 50km's away, no problems at all. Photos taken on the trip were excellent. We installed Google Translate and Microsoft Translator which worked perfectly and were a real asset in helping us navigate the foreign signs, menus, etc. We also set up Hot Spot and Tethering, and used that along with wireless calling on our US SIM based phones to make and receive free calls and texts to/from US numbers. It all worked as expected with no issues. There are two minor issues to report. The battery life was OK, I would start each day at 100% but by end of day it typically had around 30% remaining. My new (locked) S23+ easily gets two days on a single charge. I did notice a minor blemish on the screen after a week of using it. At first I thought it was just a greasy smear, but no amount of cleaning has managed to remove it. I didn't notice this when I first received the phone so it most likely manifested after use. It would seem to be a flaw with the screen itself. I did not use a screen protector, which may or may not have helped to prevent it from occurring. Fortunately it's close to the bottom of the screen and has not really affected the viewing area, nor has it affected the touch screen in the area of the blemish. All-in-all I am happy with this phone. I plan to use it for future international trips as it can do what I need without having to pay the $10-a-day AT&T International Roaming plan - that soon gets very expensive with 2 or more phones. ... show more
