    Purchased 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.

    I absolutely love this phone and what it's capable of. I bought a samsung galaxy z fold 4 through back market. I chose the in fair continued one and it was hardly noticeable that it was pre-owned. I'd honestly never be able to afford such a cool phone like this one outside of back market. I have most definitely recommended them to my friends.

    Came 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.

    The 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.

    l 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!

    This is my first foldable device and I wanted one for a few years however when I look at prices I could justify the price with the device and buying it this way definitely lets me get the experience that I want to know if this is a type of device I see myself keeping and so far that is a yes.
