It's been brilliant so far. Everything has transferred across from my previous phone. I'm really pleased with this 'new' phone.

Perfect for my needs. I loved the S20FE for its functionality and versatility in terms of SD card slot and battery life, and didn't want the newest phone so I opted for the "upgrade" and the S20 Ultra is faultless to a T. I especially love how the resolution is crystal clear and the 12GB ram!? I am a heavy user and this phone is perfect.

Prior to ordering 2 Galaxy s20 ultras from Backmarket I ordered the same refurbished phones via an Amazon partner. Both these phones had faults whereas the Backmarket ones work perfectly. They were delivered promptly and are in great condition.

In a bid to gift my wife a birthday surprise, I ordered Samsung Galaxy S20 Ultra 5G 128GB for her, which she turned out not to like because it didn't meet her expectations. However, the phone was neat and nice except that the battery wasn't so great. I also expected the camera to be superb, being 108mp, but surprisingly, it didn't meet my expectations. As a result of this, I had to return the phone, and I must say the whole process was seamless and remarkable. My customer service experience was quite outstanding.
