Verified purchaseReviewed 14/08/2026, United Kingdom.
5/5Hi I was very happy with the quality of the phone as it in perfect condition. However I requested a 128GB model and on looking at the available memory it says its capacity is 64gb see attached photo. However I have already set up my phone and don't want to go through the bother of returning it as apparently from the incorrect memory I am very happy with it. Best wishes Michael

4.9/5It went very well, newer than my old version of the same phone. I now understand the bio metric operation. I had a problem moving the contents from my old phone by the wi fi system, 2 apps did not transfer well and I had to reload them.
