Verified purchasel was thinking that the phone has going to have minor scratches and blemishes by it's rating, but it was almost perfect honestly. The only thing that I could really find was a minor scuff along the frame, and that was almost taking a magnifying glass to it. The battery life is amazing and the physical condition deserves a higher rating than they did. if this is what they consider to be good I can only imagine what an excellent must look like!

Verified purchasePurchased on Feb. 23rd, 2025 - Galaxy Z Fold 4 Beige This is not a review of a Samsung phone. This is a review of the refurbished hardware that I purchased through Back Market. Initial thoughts: fast delivery, good packaging for shipping. Out of the box, the condition of the refurbished Z Fold 4 was surprising. Inner and outer screens were pristine. The hinges feel strong, with no dents or scratches on the outer phone case. Overall, the unboxing exceeded expectations in terms of the phone's physical state. As of March 10th, I've had the phone two weeks. No glitches or dead pixels. After updates (Samsung, T-Mobile and Google), reinstalling apps, verifying logins and fingerprints, and daily use, the phone moves quickly between apps. Loads internet pages near instantly, and the speakers are loud and clear. Maybe I got lucky, but I have zero regrets and zero complaints about this purchase. This comes from a cynical buyer.

Verified purchaseCame out in excellent conditions, 3 days to come in. Would recommend doing a 2 year warranty if you can to get the most out of the device since foldable phones (especially refurbished ones) tend to have a problem or two at some point later down the line, otherwise fantastic product and I like the offers for keeping the device for longer.

Verified purchaseThe phone is great, it's fast, looks beautiful but the front screen has some sort of ghosting effect or some sort of damage. It's easily visible while in a white background, you can see some letters and icons that should not be there, so it bothers me a lot. The inner bigger screen is perfectly fine, looks beautiful.

Here’s what you help prevent on average by choosing a reborn smartphone over a brand new one.
That's like driving an SUV from NYC to Chicago.
That’s around the weight of a baseball.
That's like 20 dogs digging in your yard for a week.
That's like running a faucet for 3 days
