    • Great phone, excellent performance and value
Service provider: Unlocked Color: Phantom Gray Size: 128GB

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. ... show more

    • Excellent so far
Service provider: Unlocked Color: Phantom Gray Size: 128GB
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. ... show more

    • Good, not excellent condition.
Service provider: Unlocked Color: Phantom Gray Size: 128GB
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. ... show more

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. ... show more

    • Try another model if you don't love charging.
Service provider: Unlocked Color: Phantom Gray Size: 128GB
Phone came in great condition, easy instructions, accessories, and works well. BUT, the battery life is horrible compared to my previous phone (A32). Just sitting idly this phone is dropping 10%. I have battery saver on, reduced brightness on the screen, disabled apps that come with the phone, nothing else running (because I haven't fully set up anything) and I'm at 70% after approximately 12 hours. That may sound good to some but, I have only made 4 texts and checked a few emails. My A32 has not been charged since I got this phone a week ago. I still use it via wifi to occasionally check apps I haven't signed into on the new device (because I hate all the setup). The A32, was at 19% . This phone also has a smaller face. I wish I had done more research. Update: after writing two other reviews, down another 4%. Ugh. ... show more

    • Lasted only a few weeks
Service provider: Unlocked Color: Phantom White Size: 128GB
The phone was in new condition, it came in a white box with a charger and usb cord. Works great and my only complaint was the size. The screen is very tall, but was far too narrow for a decent sized keyboard, so I am finding it difficult to type with large hands. Phone was perfect for its size. The actual screen width is 67mm vs the Ultra with a 79mm horizontal screen width. Update, phone screen stopped working and went black after a few weeks. Lost all my contacts and accounts. Note, phone came with Samsung messaging and was attempting to force what they called an upgrade to google messaging (malicious app) update: screen started working again at random, then mobile network quit for a few weeks, then randomly started working again. The end call button does not end calls at all, it is just for looks, a glitch across multiple models by samsung. There was never any issue with the hardware, it works well.. the samsung software and firmware just isnt what it used to be. ... show more

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!
