so far this device is basically flawless. the interior screen was impeccable and the frame is almost flawless with scuffs that i only notice while deep cleaning and looking really close and a very small minor mark on the front screen that i only see when the screen is black. very happy with even fair condition

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!

Two weeks in, not a single issue. Ordered an excellent condition zfold 4. Started right up, and has worked perfectly since day one. 100 percent chance I'll never buy a brand new phone again. Back Market refurbished is truly the only to go. My one tiny gripe is that it didn't ship with a sim card removal tool.

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 think it's debatable what condition this phone is in. The bottom speaker buzzes and needs to be replaced. Cosmetically the phone looks well taken care of but still used. The polished edges have some scratches and the rear glass needed to be deep cleaned. Overall, this phone needs to be repaired out of the box which tells me it wasn't refurbished at all and I would consider that fair condition.

everything with shipping was amazing! back market is most definitely your go to shop for all electronics. you can't beat their quality, their selection, and there timing! they are the best electronics shop I have found yet! product review is only three star however because of one thing ...the front screen is so little you can barely text on the keyboard. I've changed every setting imaginable and the key word just won't enlarge enough to make it practical for using the front screen keyboard . other than yeti love the phone and the service from back market is unparalleled in my opinion! thanks back market for all youre doing for your customers and the world with your refurbish program!
