I myself have had the A31 for three years and am very happy with it. As with the other Samsung mobiles, it is very easy to use, which inspired me three years ago to recommend this one to my wife after the old mobile stopped working, and she is also very satisfied.

I'm not the user. And the user has just been hospitalised and can't reply to this message. But he says he's very satisfied.
