Software Problems with Sony Xperia Z

[JackWalsh1]

My Sony xperia z's sound isnt working. No sound comes out of the internal speakers no matter what app I'm using. But I can use speakers, headphones etc. I can make phone calls and I can hear the person at the other end but cannot hear it ringing. So I don't think there's a problem with the hardware I think it is a software issue since I CAN hear the other end of phone calls. Also my front camera has also decided not to work at all. I am running kit kat 4.4.4. I don't want to have to root the phone anyone know a solution? please.

Try performing a system repair using PC Companion as this will often fix issues - This will factory reset your phone and erase all data so best to backup before you begin

Switch off your phone and unplug from Pc (Hold volume up and power for around 10 seconds)
Start PC Companion and select Support zone then Update my phone/tablet then in Blue Repair my phone/tablet and follow the on screen instructions - When prompted connect your phone still switched off holding volume down or back button - This should start the repair or reformat process

If you are using Windows 8/8.1 or a 64bit operating system then adjust the settings for PC Companion and run in compatibility mode and chose Windows 7 or XP
