Xperia Z1 Compact reboots itself during phone call

[sevensys87]

Sometimes my Xperia Z1 Compact reboots itself during phone call. I just bought it a few days ago (04.01.2015). It has the latest software update available for me  (14.4.A.0.157). No additional programs from Google Play market are installed.

Could be a faulty Sim card as is often the case with system restarts - Check your Sim card is free from dirt etc and is fitted correctly or check if possible with a different Sim card

I already thought the same way. The reboot happened twice. After the first time i changed old SIM card and inserted a new one. And with the new SIM card it happened again.

You need to either return your device to the place of purchase or contact Xperia care http://www.sonymobile.com/global-en/support/contact-us/
