I am having a multiple issue with Xperia Z3+.
I am quite sure the problem is all starting with the adhesive getting loose. I have to agree that it used to get hot while playing games.
Its expensive in Norway just to send the mobile to Local support and they will be charing me when they return the phone as well.
I have though send them the phone for warrenty claim, hopefully sony takes proper action to fix the issue.
