I have not problem with led on during calls....before update some people want to have always on led during call..after update some people dont want it!!!
However there's alternative ways to turn off the led and still have notifactions!!
Maybe Sony wants to keep everyone satisfied!!
Yeah,it might be.Maybe sony will say something about it.
