Cannot hear caller on Xperia Z

[Shelby027]

Hi, I bought my Sony Xperia Z in May 2013, about a week ago I've been receiving/making calls and I can hear the caller and they can not hear me?  Please advise what to do, I'm thinking maybe it's a setting I changed without realising?

Thanks,

There could be a few reasons for this, however it would be worth running a firmware repair to at least rule out a software issue:

To repair the phone software
1.     Install PC Companion on a Windows PC from Support
2.     In PC Companion, under Support Zone and click Start.
3.     Under Phone Software Update, click Start.
4.     Click repair phone.
5.     Follow the on-screen instructions.
