Re: xperia z1 touchscreen problems

Okay I'm back with some good news. I tried everything like flashing, installing touch screen calibration apps etc. but none of them work. I throughly cleaned and installed a glass protector few days back and since then my touch screen is working fine.

For further info check this out :

Re: xperia z1 touchscreen problems

I solved this problem with my phone! The reason is in bad electrical contacts of touchscreen.

 

I discovered that when squeezed lower part of phone bit harder than usual. Surprisingly I discovered new menu on the screen. I repeated experiment several times and could be able to reproduce different touch screen reactions without touching of the screen itself. Just squeezing or twisting the phone, nothing more... The reason of incorrect touch screen behaviour became clear. Bad electric contacts in the lower part of touch screen. Some mechanical deformation leads to unpredictable reaction of screen to user actions. Switching off the screen could solve a problem temporarly because of discharge in some electrical circuits but after switching on the screen "almost good" contacts returned to their "jitter".

 

Clear that screen protector cannot solve a problem.

 

So, how to fix? Some twisting, bending... After several "brute forcing" of the phone I got perfectly working touch screen. Electric contacts returned to their correct positions. And I made screen recalibration.

 

Definitely, my next phone will not be sony with its bad assembly quality.

Re: xperia z1 touchscreen problems

I had troubles with touchscreen. My colleague had problems with battery. Sony does not want support z1 and provide new android...

 

We moved from sony to another smartphone vendor. That finally solved the problem with terrible sony products and support policies.
