Great phone, excellent performance and value
This Samsung Galaxy S21 5G has been a great purchase. The phone works perfectly, runs fast, and is very easy to use. The screen quality is excellent, with bright colors and sharp resolution. The camera takes clear and detailed photos, and the battery lasts well throughout the day with normal use. Even though it is a renewed phone, it arrived in very good condition and looks almost like new. For the price, this is an excellent value. I am very satisfied with this phone and would definitely recommend it.

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.

Good, not excellent condition.
Item was promptly shipped and arrived in good order. Packaging was acceptable. The phone was not in "excellent" condition as described - it had minor scratches on the case. Screen is damage free and it works well. Battery life is as expected for a phone of this vintage. Once enclosed in a case the superficial scratches to the case were no longer visible.

Nice cell phone
This is my first time buying a cell phone from Amazon. I onky ever purchased directly through my carrier. I am 100% satisfied with this purchase. I will never buy strait from a carrier again. This cell phone arrived and looks brand new. The delivery eta was on par. Not one blemishes on this cell phone. The purple color is so pretty. It was so easy to activate/set up. I recommend this seller and this phone.

Love the phone
Have had this phone for a week so far and it's been great. In great condition, phone works well. Was nervous buying a refurbished online esp Amazon but it was a good experience so far!

Works well, but definitely NOT 'Renewed - Excellent' condition.
Finally pulled the trigger on getting a new phone. I used to use a Galaxy S8 (what I used to take the pictures) and it held together for a good 5 years. However time and wear had taken it's toll. Battery lasting 8-10 hours with light use, a few cracks to the screen, you get the idea. I decided to keep with Samsung as I rarely is ever have issues with them. I had an LG Stylo for less than a week before I went with the S8 after my S6. Found this deal. Advertised as 'Renewed - Excellent', and I knew what quality that would be as that's what my S8 was when I picked it up. So I went a little over budget to pay that premium. It wasn't quite worth it. Pros : Battery seems to be great, lasts about as long as the first ads for the S21 Ultra when it first dropped. It's now day 4 since I decided to test the battery and keep it off the charger. With light use, I'm still at 39%. The fingerprint scanner hasn't given me an issue yet, Audio quality on calls and playing music is better than I was expecting to be honest. The 5G is a lot better than the 4G I was at with my previous phone. The camera is working pretty well, though the 100x is a bit too blurry, but at 50x, for example, it's definitely usable. Screen quality still lives up to the hype, though I still need to tinker with the phone settings as the color seems a bit oversaturated. And, for a user of Boost Mobile, this has been the fastest switchover from phone to phone I've ever had. No calling in, no visiting a physical store, not even punching some numbers into an internet portal, just literally took the SIM from my S8, slid it into the new phone, and in seconds I was active. Even the Boost Mobile site had the updated phone information already registered. Cons: Here's where my praise kind of ends. As I said, it's not in Excellent condition. There are two noticeable scratches on the screen. On mid way up the phone from left to center that I can see at arm's length, and one in the lower right quadrant that I can see when the light hits it just right. At lest you can't see them with the screen on. Man, those two hard to get clear images of. I might not have noticed them if I didn't remove the ill-fitting screen protector with plans to replace it. There's some deformation in the bottom right corner as if that's where they used a metal tool to pry up the old screen. It's not sharp, but you definitely notice if you run your finger over it. The charge port is deformed as well. Slight bend on the rear side towards the front. Not enough to interfere with plugging it in, but it's there. And speaking of ill-fitting protections, the camera were covered with a piece of tape. Even after I removed it, it took more than a little work to clean off the adhesive that was left behind. They seller was 'nice' enough to include a cable and charger. The cable is a sub-standard 4 wire USB-A to USB-C. At least the data lines were connected so I could get SOME use out of it, but no chance of any change plugging it into a USB 3.0 port, as opposed to USB 2.0. The charger itself was a basic 5 volt 2.1 amp mini brick. I'm glad I already had the proper charger and cable so I could get the proper charging speed. So understand that you might not get what's advertised. According to Amazon's own policies, this should have been 'Renewed - Acceptable' at best. That $40 difference, from sellers providing the same, I could have put toward a case, proper screen protector, and maybe even a charge/cable bundle. Definitely not worth the full price I paid.

I broke my old phone and started shopping around for a used S21 on Marketplace/Kijiji for a replacement. Many phones had defects (scratches, dents) and others were not competitively priced. I was surprised to find Amazon refurbished phones selling at the same price as what was available on these websites (inclusive of sales taxes where I live), while also eliminating most risks associated with buying a used phone by providing a 90-day warranty and a 30-day return option. With the Amazon seller, there's also no risk of the device being blacklisted. I received the phone a couple of days ago and I was very pleased when I first opened up the box. The phone was rated as "excellent" by the seller and it was indeed nearly perfect. You would only notice that it is used if you looked very closely under a bright light and observed micro scratches in a couple of places on the aluminium frame. Looking at it from beyond 10CM away, it's nearly impossible to see any signs that it's a used phone. I ran full diagnostics by dialing *#0*# AND I also used the Samsung Members app diagnostics test. I also checked the battery capacity. Everything appears to be stellar, including the battery life. The phone that I received also came with an original Samsung fast charger which was a pleasant surprise as well, as they advertise that it may come with a third-party unit in the ad. I was originally concerned given some of the reviews, but it's been a great experience for me. Give it a shot, with the return policy, there's really no risk (especially compared to buying a used phone from a random individual...).

I received a sim locked device that needs MCK lock and doesn't support any sim card. Very disappointed after long delivery time

Al principio dude pues nunca había comprado algo reacondicionado pero me terminé animando y fue una excelente decisión. El celular es prácticamente nuevo, funciona al 100%, la cámara es increíble, super profesional, un celular bastante rápido y de super lujo. Venia con pocos detalles estéticos en los bordes, pequeños puntitos sin pintura que realmente no se notan nada, de ahí en fuera el celular venia en excelentes condiciones. 5 estrellas definitivamente 👌🏻 me hice de un celular de lujo por un precio super bajo para la gama alta que es. Lo recomiendo mucho.

Llevaba tiempo queriendo comprarme un samsung gama alta, tenia un s10 que ya se me estaba quedando corto en el tema de actualizaciones y eso. Encontre estos reacondicionados y pues no soy muy de escribir opiniones de los productos que compro pero como este telefono en sus comentarios no encontre información importante aqui dejare lo que le hubiese gustado a mi encontrar antes de comprar el telefono. 1. El telefono obviamente vino en caja generica, bien protegido, su factura y sello de la empresa que lo vende (Que hay que guardar estas 3 cosas por si se requiere reembolso) 2. Trae un cargador, obvio no original pero si se ve de muy buena calidad, incluso es de carga rapida, al menos el que me llegó a mi (Cabe aclarar que yo pedi el color rosado) 3. Llegó como nuevo, este me lo vendes en una caja samsung y dudo que sea reacondicionado, la verdad está hermoso y tiene CERO defectos. 4. Viene con el procesador Snapdragon 888, lo veo muy bien es mucho mejor que el Exynos 5. El telefono me llego hoy 13 de junio, un eia antes de lo que mencionaba Amazon, son puntos extra, pero como no llevo ni un día utilizandolo pues si algo sale mal vendre a editar esta opinión. 6. Si agarró señal de una, soy de TELCEL e incluso funcionó el 5G. Espero les haya sido de ayuda... A mi me hubiese gustado saber esas cosas antes de comprae aunque hasta ahora no me arrepiento pero si fue bajo mi propio riesgo
