Xperia Z3 call setting

[IoanaJ]

Hi,
I searched everywhere în my Phone call settings but I don't find something about my problem.
When i'm talking with somebody if i receive another call and I take the phone from ear to look who's calling the phone answer automatically to the second person and put the first one waiting.
Can you please help me if know something about?
Before Xperia Z3 i had Xperia P, the same menu but don t have this problem.

Best regards,
Ioana

@Alexdon I am from UK and the digimobilr is one of the sims I use in Spain
On the bright side I won't need it after April as Spain has joined the list of feel at home countries on 3 UK.So don't need to change sim then
