My xperia asks me to update system to 18.1.A.2.25 Done that twice and twoo times used tech. services. They restored previous system version and said dont use Google account sinch. Problem is, that after update, fails sound services: not posible to use telephone, looks like mic off and speaker is off. No ringing, no music and so on.. Now im not updating system to... 25 and it works fine. Google account sinch. Works fine and i think its nots relaited. So what do you think?
