  • Very Happy With This Purchase
    The phone was in excellent condition with no blemishes. It appeared to be brand new. I was actually shocked when I set the Samsung A52 down beside it and the display showed it was ready to copy to the S21. After checking the boxes, it copied from the old Phone (that had issues with almost everything) to the new phone in 23 minutes (48gB).

    All the apps and more importantly photos and contacts all copied over. The only work we needed to do was put in passwords for some of the apps to get get connected again.

    We were extremely pleased with the product and it has been working very well. I would add, there was no charging cord with the phone, but it uses the standard USB-C and we have several of them laying around. It charges on a wireless pad, but if you put a case around it, it did not work, but we prefer to have the protection of the case, rather than wireless charging.

    Overall, very happy with the product and the price.
  • Excellent so far
    I ordered it on Sept 20th at $339 plus shipping of ~$34 and Morocco VAT of ~$80, so totally I paid $449.

    Delivery was very good. I saw it was shipped on the 25th. On the 30th, I received an SMS from DHL saying they planned delivery on Oct. 3rd, but on the same day I got an email asking for copy of national ID and content description for clearing customs. I am not a Morocco residents nor citizen, so I sent my foreign passport instead. On the 3rd, Amazon tracking info said clearing custom was delayed as additional documents were needed. So I called DHL, and the rep said it would be delivered on the 4th instead. On the 4th, I saw a newly posted message about delay on Amazon tracking. I called DHL various times but couldn't get to anyone. I then sent an inquiry by email and get a response shortly saying it was being taking care of. Then late afternoon, I got the package.

    Upon arriving, the seal of the packing had an opening large enough to put in a hand but not for getting the phone out, so I didn't complain.

    Unpacked, the inner packing of the phone was in excellent condition, very much like the original packing but had no Samsung marking, rather, it had a marking of "amazonrenewed". There was a film covering the screen, like on a new phone. The phone appeared in excellent condition, only had a small scratch at the back when I looked in detail, and a hair of scratch on the screen that is only visible under bright light and in a particular angle. I tried but couldn't turn on the phone - there was no response. The box also included a USB-C cable and a cheap non-Samsung charger made in China. I used my own Samsung Charger to charge the phone. After plugged in, it showed the battery was at 0. So I let it charge to full.

    After started, it turned out fully unlocked. My Morocco sim card works with 4G. The phone's software looked already reset, but I reset it myself anyhow. Then updated to the latest system with Android 12, and loaded many apps I need. During about the first week, the battery appeared quite poor. With medium usage it lasted about a day. I tried all necessary settings to conserve battery, but it didn't seem to help much. These couple days, it becomes much better, lasting about 45 hours. I read it was likely due to some AI processes either from Android 12 or Samsung doing the learning work at first. But it's pretty bad the phone doesn't show any info.

    I would say I am very happy with the phone. And this is after having a terrible experience in the past with Samsung.

    The last Samsung phone I had was S7 Edge bought in Thailand (I am a traveler), new at a Samsung store for perhaps ~$800. I actually wanted the normal S7 (without the "edge"), but it was out of stock then. I never liked the "edge", it was a silly design in my mind. The phone worked well initially, but in the coming couple of years I had a terrible experience. About 5 months later when I was in Vietnam, the screen started to show shaded bands across. As I was wondering how or if I should return to Thailand to get the phone serviced, the bands disappeared after a month. Then about another 7 months later when I was in Azerbaijan, the phone couldn't start after I did a system update. So I couldn't use the phone for a couple weeks until I reached Tbilisi in Georgia when I had someone flashed it. About a year later, it died on me again when I was in Morocco. I had someone re-flashed it, but it was not successful. About 1 month later I reached the city of Fes where there is a Samsung service center. After checking, they said there was something wrong with the motherboard. Very shocking! I've never had such problem in my life with all the phones and computers, cheap or dear, and this was a flagship! So eventually, I sold it to a local repair shop for $200, for which they said they only needed the screen. That was end of 2017.

    So I never bought a Samsung again, and would definitely not buy one at the full price. I admit the S series is not worthless. At least, I like the camera. But I never had a chance to buy one at a largely reduced price (I won't buy from just any second-hand sellers).

    So now, the Amazon reviewed phone with some warranty got me interested. Yes, I have some risk, but to me with the past experience, the risk is not much higher than getting a new phone from Samsung, plus, I am putting in a much lower bet now.
  • Horrible Product
    If I could give zero stars, I most certainly would. I am highly dissatisfied with this product. I purchased this phone and selected the option, refurbished (excellent condition). The phone came in a timely manner. However, the product was not as expected. The phone was completely dead when I received it, so I charged it full to 100%. When I went to switched my data that was successfully and quick. However, the phone seemed to be very hot, even when I wasn't using it. I also noticed the battery life is horrible. Remind you, I charged the phone the whole day. By the time I completed the setup it said I was at about 72-75 percent. I took an hour nap and woke up to a hot phone and battery at 2 minutes. I figured, may be it was because I completed the setup prior and that drained the battery. However, no I charged it once again (it charged super fast) and then I noticed within 45 minutes it went from 100% to 72% back to 90%. It's as if the battery as a mind of its own.

    I then notice my WIFI was on. I typically don't use my WIFI for my phone, so I figured let me turn that option off. As soon as I turned it off, it stated the sim from previous phone was not compatible. The phone is not unlocked. It is under Verizon (which shows once powering the phone on) and no matter what I do, I am only able to use the device under WIFI. I have Metro PCS not Verizon, so this phone is not properly unlocked it is still under the Verizon network.

    The phone also seems to have possibly been damaged before I received it. It looks like water damage, and whomever had the device tried to fix it. However, the back of the phone near the camera looks like water got in it, and the front screen has some indications of possible water damage. Oh and not to mention if you go into the about settings it says the phone is an S22 when switching over data, but when I switched back to my previous phone, it shows S21. Very weird. Anyhow, just so much wrong with this product.

    I have purchased two phone via Amazon in the past. The Samsung Galaxy S22 Ultra and the Samsung Galaxy A16, and both of those devices were amazing and worked perfectly. However this purchase of the Samsung S21 5G is horrible. I am very upset I purchased this item and whoever stated this was in excellent condition lied 100%. I will be sticking with my previous device and returning this mess of a phone. I literally just got the device today and already many red flags and unsatisfied. I will be returning this product and getting my money back immediately.
  • I missed Samsung Galaxy phones so much!!
    I just got mine and spent a full 24 hours with it. I really like the phone. It feels good and has so many great features. After system updating it like 8 separate time, it was easy to transfer all my stuff from my old android to this new phone. My only complaint is that the battery life is not the greatest, but I also use my phone a lot so it might just be me. I still learning this phone, but you can have 1 Sim and a few E Sims. There is a fingerprint sensor ingrained into the screen. Camera is decent. I'm not a camera expert but I'm satisfied. But yes great price, great phone. I hope I keep this for 3-5 years.
