Just got a massive bill from my mobile provider - Z1 pcket dial problem/fault

[Myphonebillisma]

There seems to be a fault with my phone making unwanted calls with out my knowledge. Is this a common problem with the Xperia Z1s?

That could be an app acting up, do  you actually see the calls on the call log?

[Myphonebillisma]

Thanks - yes, the calls are listed with times on my call log so I don't think it's an app/data gobbling problem. Need to check with the people who're said to have received those calls... the nasty shock of a sky high bill

@Myphonebillismassive

so it was a buttdial issue?

If you think it's an app creating this issue, you could repair the phone with Sony PC Companion
