    The Samsung Flip 4 is an excellent phone. I have owned one for 2 years and loved to flip it closed. Its easier to carry and great to take pictures and videos with, especially when it half closed. You don't need to shoved it in their face ! The only problem is the phone is known to wear after it has been opened and shut hundred of times and the connection between the two halves stop working with costly repairs. For me it lasted two years. Could be worse, could be better. Would I buy a new one ? No. But I am happy to buy a replacement from Back Market for a fraction of the cost ! Absolutely. The replacement looks, as new. Cannot fault it. I'm Happy.

    I have wanted a Samsung Galaxy Flip for ages. I don't need the latest version of a phone so I was happy to opt the Flip phone 4. I am very pleased. The phone looks brand new, the screen is amazing. If I used my phone more I would be concerned about the length of battery charge but for me it is fine.

    Bought this Samsung z flip 4 in excellent condition was cheaper than buying it in good condition Came next day and to my surprise with the original box too. not a single mark or scratch on the phone 😁 I was very anxious while buying this phone I've seen alot of bad reviews, so I also got insurance with it too. Happy it came with one year warranty too just In case (i also bought a case) All positive things at the moment, il update the review in a few weeks to say how it's getting on 🙂

    Fantastic service and purchase. I was a little worried about buying a reconditioned phone,not knowing what to really expect. But my concerns disappeared when my Flip4 arrived. The condition said very good, but it was like new. Not a mark or scratch on it. I've left it for 2 weeks to leave a review just so I could be confident in the phone's operation. Again it's just like a new phone and hasn't missed a beat. I certainly won't be buying a new phone again. I had to buy a charger and cable separately even though a cable came with the phone. That's just so I could charge at 25 watts which is much quicker. Excellent shopping experience.

    So pleased! This is my first experience using Backmarket and purchasing a refurbished phone. The quality of the phone is like new and was packaged really nicely with a charger. So far I have been using the new phone for a couple of weeks and it's met all of my expectations. Affordability is a huge thing for me too and being able to get student discount was extremely helpful. Will definitely buy from you again when it's time for a new phone. Thanks again!

    wanted a flip phone but didn't want to spend out to much on a contract and not like it...my daughter to me about back market... had a look and found the galaxy z 4 flip phone...ordered on the 22rd and it arrived the next day 5⭐️ for that ☺️ I went for the "fair" condition.. and can't find one mark on it, screen and back in excellent condition,5⭐️ again...only downfall is the battery life but im used to charing my phone during the day due to my usage..my old phone was a Samsung so no problems setting up and navigation, overall happy with my purchase and will definitely shop here and in the future 😊

Reborn vs. brand new

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

77.3 kg of carbon

That’s like driving an old banger from London to Edinburgh and back.

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.

77,000 litres of water

That's like running a faucet for 3 days
