Use my wife's Z2 for a while and wanting to buy but fortunately didn't because the phone been having call quality issue as in the other party can't hear clearly, sound muffled or voice breaking up. Send the phone for repair 3 times! Sony service center even change mother board and casing but voice quality is ok sometimes but break up most of the time. My sister's Z2 though she say got not issue but at times voice sound distance too.
In the end, my wife sold it yesterday!! Total frustration and dissapointment!!
