[dawp83]

Hi guys, I'm the owner of the Xperia Z1 for 2 months, and if I play demanding games, phone is getting hot, I know it's normal, BUT, when the phone is really hot, touchscreen have some problems, when I drawing lines, something interrupts my drawing, and when I'm moving in games which need to hold the thumb on screen, sometimes it interrupts too, I read a lot of forums about Z1 touchscreen problem, but i dunno it is software problem or hardware O.o plz help.

Whenever the phone gets hot use this app Xperia Diagnostics to test the touchscreen

I was using it for a few times, and lines interrupts only when the phone is hot.

Whenever your phone gets  hot boot on safe mode and check if you experience the same issue

Yes it is, only when it's hot, when I using it normally, like facebook, youtube, or low demanding games touchscreen is fine...

PS. I read a lot of posts about touchscreen issues in Z1, is it a factory issue? Or software issue or hardware?

one of my friends , today has bought a brand new xperia z1, tho i warned him, and he ignored me saying that mine was defective, and guess what, KA booom

it has the same problem as my unit hahaha, you guys should've seen his face

still the sony guys won't reply to me cause they know the problem and still shy about it, we wen't back to the sony shop, they told us that many users who have z1 compact and z ultra are coming for the same fault, 

do you guys think it's a driver problem related to the snapdragon 800 ?

come on guys let this thread alive again, if you make it die, sony will live you with a defective phone as long as you still own one of their dragon 800 device.

this is very sad, as i find the xperia z1 much snappier than xperia z2 and z3

My Z1 doesn't have any touch related problems, only simple warm. So, mostly.. it depends how is the Z1 you get xD.
