Xperia Z5 worst phone ever!

<p>After puchasing a Sony Xperia Z5 in November 2015 I have just had problems. The phone went in for repares twice still not working. ! I received a new Sony Xperia Z5 yesterday and after all the updates and transfers last night I tried to use it this morning....... as I made an outgoing call the phone just went dead after 5 min I got it back on again (This is how the problem started) I got into my car and took it back to Vodacom Menlyn where the manager advised me that it is the protective film on the phone that is causing the problem!!!!!! I call BULL ****!!!! This is not the product i expexted form Sony!!!!!</p>
