Samsung Galaxy S23 Ultra review (2025) | Back Market

The Samsung Galaxy S23 Ultra remains a compelling high-end smartphone in 2025, offering a superb camera, powerful performance and the unique S Pen. The slightly older status often means more affordable prices, especially on platforms like Back Market.

I bought the phone as a gift for my partner and we only set it up yesterday. It's a lovely phone (one up from my own) and I really like the protective case that came with it. The protective screen went on perfectly and my partner is very happy with it. Beats the crappy thing he had before, but don't tell him I said that.

It fitted beautifully with the iphone I bought from Back Market. But that is in the final return process and I've bought another iphone elsewhere. Not tried to fit it to this one yet, but can't see any reason why it won't be fine.

Always a bit stressed about not wanting to break my phone, am so glad I could just buy a cool looking case and screen protector with a couple of clicks. Took less than a minute to put on too!

Absolutely brilliant! Second phone I have purchased from Backmarket and just as over the moon with this one for my husband as the one I bought for me. Immaculate condition. Just like new! Hubby loved the silicone case, too. Very good quality. I would not hesitate to recommend Backmarket and will never buy a new phone again when you can get such good refurbished phones in this way. Very good prices. Excellent customer service and communication. Thank you!!!

The case fitted perfectly - the protective screen that I fitted was also a good fit. However, fitting the protective screen was not easy - making sure the gap either side and top and bottom were even was not easy. Maybe a plastic surround going to the edge of the screen would automatically make sure the protective scree
