Several problem with touchscreen

I have a C6903 and Android 4.3 (14.2.A.1.136)... The touchscreen work fine in normal use... But when i play and the Phone turns hot with a high temperature the touchscreen too, then it starts to work very very bad (when i touch on one point starts to do 'circles' por order actions that i didn't do...). What should i do? Is it a problem for SAT? Sorry for bad english, i'm spanish.

About the white circles,did you change anything in developer options?

Re: Several problem with touchscreen

I tried to do that in safe mode, but i can push the phone to the limit... Because the problem is when the phone turns hot because increase of temperature... Even when i want to put my pin the keyboard touch in other sides... When the touchscreen is hot and i push a letter, it pushes many letters or starts to draw lines when only i push in one side...

All of this is only when the phone and the touchscreen turns hot...

Re: Several problem with touchscreen

the problem with the touchscreen have been very irritating in the past firmware, n also in the latest 4.4.

 

look at this thread, http://talk.sonymobile.com/t5/Xperia-Z1-Z1s/xperia-z1-touchscreen-problems/td-p/410611/jump-to/first...

 

even repair through PC companion or SEUS a thousand times, it doesnt help.
