maintenance update has eradicated all heat issues completely!

I can hardly believe this but I now have no heat issues after regular to heavy use on all of my Z3+ phones!
( I purchased several of them at a very deep discount)
It is running much cooler than Z5 and running exactly the same temp as my Z3..... even battery life seems to be greatly improved.

Thank you Sony, please do not mess this up with future updates, Z3+/Z4 is now, for me, the perfect Xperia phone

The phone still heats up mor so with Internet use. I have stopped using back cover for allowing heat to dissipate from back
