here's the result after i removed the screen protector...

no issue at all. typing (or swiping) is good without any problem.
i think the screen protector is kinda... "oily" (or maybe its surface is just too smooth?)
too bad that i have buang the case of the screen protector, not sure what's the brand. it should be banned, forever.
now, what is brand of the screen protector that u guys are using? my phone is naked now!

Lucky solved, means same issue as Xperia Tablet Z, only certain screen protector can use.

hey..u know , it gonna be kidding all of us...after i removed sp...problem solved..try remove your sp....wth is this problem..first ever occur to me...last time my xperia z also put sp...but no problem at all.
btw, my sp is clear type from nillkin.
I think Sony use different type scratch proof sheet, I notice this Z Ultra or Tablet Z is much scratch resistance than Z also.
