Not in mine. Screen stopped working as I used the phone. Never dropped it. Under 3 years old and cost £500 new. Never buying another Sony phone.
Did you approach Sony for a repair, and if so, how did that play out?
I tried to get Samsung to repair my two year old Galaxy when it turned off one day and refused to turn back on, but as it was purchased in a different country they refused to help. Haven't bought a Samsung since.
