After 2 weeks of thinking and hesitation, I just ordered this from Amazon (UK) as a jump from my 2 year old Xperia Z2. Hope it works well (the seller is reliable) and I hope I am able to place the screen protector properly (I've ordered the one that is applied with liquid)! And even if some problem occurs (overheating or TouchWiz problem), I hope I can get here on the forum for support from you, nice fellas. Excited!
