Hi all, just bought xperia z1 from directd, ap set about 2 week ago. Updated to 4.3. I would like to know, is anyone else having problem with the touch screen? Sometimes it doesnt register well the touches. Im wondering whether this is a hardware or software problem

The touchscreen problem is like u're able to tap but unable to hold the tap right?

definitely screen protector issue, previously using nillkin sp, will happen when the sp is quite oily, then i ordered tempered glass sp and b4 it arrives, i tried using the phone for few days without sp, never happen even when its oily.. and with glass sp on, it happens once or twice, quite rare..

Please update here after testing. I wanna know if its really SP that causes the problem
Oops sorry didnt see that. Well yeah, i notice it happens mainly after i play around with my phone for a while (games, browsing internet) and the SP becomes quite oily, but then if i let it awhile, it doesnt happen again. Meaning the SP is still oily but there is no problem with the touch screen. This has been bugging me ever since.
