I have just updated and i can say that phone is smoother and there is no more lag when you try to view picture that you have taken inside camera app it shows it almost immediately also launching camera app is faster for me and photos are taken faster and with less noise in night. Thats the things that i noticed from my view on my z5p a guess it the same things for z5. Also mobile data icon is now separate from signal icon.
BUT SADLY STILL NO XPERIA X SERIES UI
