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.

Excellent purchase! Very good value for money. I bought a Back Berry from you 5 years ago (which did me a lot of good), and I've upgraded to a higher quality phone with this one. Thank you for giving us access to this type of device at a reduced price. Yours sincerely, D. Brouillac
