Seriously fed up with not 1 but 2 Sony Xperia z1 mobiles with very frustrating text keyboard issues. Both since new continually errors had when typing. I type example "a" and get a completely random keyboard letter. Have to keep resetting phone. Really annoying. Anyone else have this issue? It getting much worse. Was advised to send to get both fixed but contract up in 2 months so might just get 2 new contact phones in high street. Never getting a Sony phone again, terrible.
