    Only a single small scratch along the top. Otherwise flawless, even without a case the scratch is barely visible, I was so afraid of buying anything here but I definitely will be looking for other products now, when I hear refurbished I usually see badly finished products. When back market refurbishes something it is flawless

    I was skeptical About buying a refurbished model but everything turned out great.The phone is an awesome condition.And it came with a screensaver already on the phone. There was no problems in updating the phone or getting it programmed correctly.

    Delivery was on time. The phone itself came with a screen protector already on. (that was so nice) It has one or two little scratches on it but that is to be expected because its refurbished. Honestly once you put a phone case on you cant see it anymore. All in all I would recommend backmarket to friends and family. I'm so happy I got my Andrew (android) back lol!

    I recently purchased a s21 from back market in the "good" condition and I'm so happy with it that I probably couldve got the "fair" conditioned s21 and still been pleased with it!! Seriously there wasn't anything to complain about...No obvious scratches or dents of any kind and overall battery is almost 100% brand new with 96% overall battery health (not meaning 96% charged but 96% in comparison to how a brand new battery should function. This has been such a good experience that it doesn't make sense to buy the newest most expensive phone or even a midranger, I will always buy older refurbished flagships from now on, it's the only logical option. It's the equivalent of why you don't buy a car brand new as it is more economical and generally better to buy a slightly older used car if you want to be wise with your money and get the most bang for your buck deals!!

    Received the refurbished SG21 Unlocked,in a cool brown looking box with a note on box to take good care of phone, it was exactly what the seller claimed to be, more than perfect had no issue charging nor starting put sim in had service switched within minutes from wireless provider. Just perfect. Definitely will be purchasing more electronic devices, finally found a site that's honest with refurbished products spent half the US dollars than some of these other Joe burgers who want to overcharge on refurbished phones. Thanks Back Market!!! Not sure who Greg is but thank you for saving me the headache on searching for affordability of my needs!!!

    So I tell you what I bought this phone of a back market for about $250 tops for shipping and everything anyway I'm pretty satisfied but I understand if this is a used phone and there are some trade offs anyway phone wasn't perfect condition not a scratch not a blemish nothing perfect physical condition the only thing I could complain about with this phone because I feel like you can see the screen was replaced and when it's completely black you notice a little smudge underneath the glass which is understandable because it is refurbished phone which means screen could have been broken before but you only noticed this when it's fully black when you have a full black screen also I don't know what charger is I'm using exactly but I noticed that it fast charges at first and then goes to Regular chart realistically fast charge only saves you 20 minutes from regular charge other than that software has been spectacular exactly what you would expect from a Flagship Galaxy device your phone is great it is meant to do what it does and does it well also I noticed a little nitpickio though is that when you use Snapchat and you zoom in for the first time and you zoom out there's a slight lag so ...

Benefits of buying a refurbished Samsung Galaxy S21


At Back Market, customers save big compared to the price of new on certified refurbished Samsung Galaxy S21 5G models. The best part is, you don't have to sacrifice performance quality in order to save money; all refurbished devices on our marketplace have been fully reconditioned, cleaned, inspected and tested to the same standards as a new one. This is the biggest difference between buying a used or pre-owned Samsung Galaxy S21 compared to a refurbished one.

Buying a renewed Samsung Galaxy S21 is also a much better option for the environment. A refurbished Samsung Galaxy S21 5G is often a second-hand device that has been restored and updated to meet the Samsung's manufacturer standards, which means you'll be helping to keep old Samsung Galaxy's out of our landfills, reduce electronic waste, and minimize your carbon footprint.


Where to buy a refurbished Samsung Galaxy S21


You'll find the biggest selection, highest product quality and lowest prices on restored Samsung Galaxy S21 5G models at Back Market. That's because we specialize specifically in refurbished tech and take the time to carefully vet every seller on our marketplace to ensure customers are getting reliable devices that perform like-new. We have hundreds of refurbed Samsung Galaxy S21 5G phones in price ranges to fit almost anyone's smartphone budget.

Staying true to our brand, we're also a huge advocate for environmental change. In fact, at the beginning of 2023, we hit a milestone for preventing 1 million tons of carbon emission (CO2e) from entering the atmosphere. You can help contribute to a better circular economy when you shop Samsung Galaxy S21 deals on our platform. 

 

Samsung Galaxy S21 5G warranty and return policy


All Samsung Galaxy S21 5G purchases on Back Market come with free standard shipping, a 1-year warranty, and a 30-day money-back guarantee. We want to make sure you can shop with confidence and find the best Samsung Galaxy for your needs at lower prices.

 

What to expect when buying a refurbished Samsung Galaxy S21 5G


If you're a first time refurbished buyer, you might not be sure what to expect from your purchase. First, understand that your Samsung Galaxy S21 may have external cosmetic flaws depending on the condition you choose (Back Market offers devices of Fair, Good and Excellent quality). However, whatever the condition, any external blemishes will not affect the performance of your Samsung Galaxy and you can expect your device to perform as if it were newly opened directly from the Samsung Store.

You should also be confident that your Samsung Galaxy S21 is backed by a 1-year warranty, meaning in the rare case that any defects arise (outside of accidental damage) within 12 months of your delivery date, then you're entitled to your choice of a repair, replacement or reimbursement. 


Smartphone Trade In


If you already have a smartphone that you're looking to replace, consider trading it into Back Market to give you a little extra budget for your next smartphone upgrade. We make the process simple for you and we'll give you a free online quote when you answer a few easy questions about your current smartphone.
