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.

Almost no signs of wear. The body may have very light micro-scratches. For items with screens, the screen will have no scratches.

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.

Ordering was easy and I am so happy with my new/refurbished phone. I have ordered from Back Market previously and always happy with the service and products.

Je suis décu de la protection qui possède un léger défaut et qui ne fit pas bien avec mon Ihpone 13. Il y a une légère bosse au niveau en haut à gauche.

It was a perfect fit, it has already proved it worth a couple of times, so definitely very good value for money.

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!

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.

Fits well - for some reason I forgot it was transparent, not blue, but that's my own issue. The screen protector is high quality and glad I have a spare if needed in the future. No problem texting with screen protector on.

Fast delivery. The case fits snuggly on my phone. The screen protector was simple and easy to apply, no issues with trying to force out air bubbles; the fingerprint sensor still works perfectly. Very happy

Phone arrived within a few days . The phone I ordered was in excellent condition and I was very happy with it . The addition of the screen protector, the clear phone case and the charging cable all added to a very positive experience. I will definitely be using Back market again
