    This is my 3rd phone with Back Market and I continue to recommend them to freinds. If you are going to buy a refurbed phone you should buy it from a company that will provide at least 1 year warranty and will scramble should any issue arise in getting the device activated with your carrier. BM is that company! I had an issue with my first phone and a BM representative personnaly over saw the whole process getting me an overnight replacement and worked the after tge fact return process with the refurbished! They are outstanding! You can buy from Back Market with full confidence in both the claimed device condition and compatability!

    I like the phone, it is far superior to the A14 that it replaced. However, I cannot turn it off via the side key. The only way to turn it off (to restart it) is to use the power button on the home screen. I don't THINK it's supposed to work that way. This is workable, just a little inconvenient.

Reborn vs. brand new
Here’s what you help prevent on average by choosing a reborn smartphone over a brand new one.

171.1 lbs of CO2e

That's like driving an SUV from NYC to Chicago.

6.3 oz of e-waste

That’s around the weight of a baseball.

537.1 lbs of raw materials

That's like 20 dogs digging in your yard for a week.

20,341.2 gallons of water

That's like running a faucet for 3 days

Everything you ever wanted to know about the Galaxy S21 128GB - White - Unlocked

Never let a moment be missed with the Samsung Galaxy S21 Dual-SIM 5G Smartphone, which features a triple camera system and a host of pro-grade AI-supported technologies. The 12MP ultra-wide, 12MP wide, and 64MP telephoto lenses can capture a wide variety of still image types, while also allowing you to capture videos at up to 8K. With 8K video support, you can use the 8K Video Snap feature to pull out 33MP hi-res frames from within clips, so you can ensure that you never miss a chance of saving and sharing specific moments. What you see on the Samsung Galaxy S21 is just as good as what you can record, with a stunning 6.2" Dynamic AMOLED 2x screen with an adaptive refresh rate of up to 120 Hz. AI detects the content you are viewing and alters the refresh rate automatically, between 48 to 120 Hz, giving you a smooth scrolling experience when you need it, and preserving battery life when you don't. Gorilla Glass Victus protects the display with extremely durable damage and scratch resistance. A tiny hole in the Infinity-O display accommodates a 10MP camera to handle your selfies. The screen on the Samsung Galaxy S21 is how we experience all of what a smartphone can offer us, and much of that content is streamed to us via the internet. From streaming movies and TV shows to online gaming. This is why Samsung equipped the Galaxy S21 with 5G support, maximizing your ability to utilize the blazing fast speeds that 5G can offer. The phone also supports Wi-Fi 6E, which expands home and public network support into the latest 6 GHz spectrum for more stable connections and the fastest bandwidth possible. Scratch and Dent products are systems with considerable cosmetic blemishes that do not affect performance. They are a great way to save money while still enjoying a rebuilt and rigorously tested device. Scratch and Dent computers will not have scratches or pits on the screen, missing or illegible letters on the keyboard, or damage to the touchpad or palmrest.
