Hi 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

As it was a replacement for a Galaxy A21s (which) I have had for some seven years my expectations were high. I was not disappointed. Transferred all my data, wiped old Galaxy and now to dispose of. Do not regret updating. Many thanks.

It 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.

Very nice reconditioned phone. I will never buy any tech from anyone else. The phone works well and I love it. Delivery was quick and the phone was very well packaged.
