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
