Tutorial [DEV]{TEMP FIX}| XPERIA Z1 Touch screen issue | UPDATE 12/09/14

Calling all Xperia Devs!

I'm sure that everybody knows what im talking about. and even if you don't you will probably find out soon. As i only started getting the issue after a couple months.

Where do we start? i have some experience but thats only with kernels and since alot of people are facing this issue... let's try as hard as we can to need only root access.

if anybody can tell me where to start looking... and help out.. that would be great..

Let's fix this guys!


I was messing around and i think i've found a fix for the touch screen issue.

What you'll need
  • Root
  • Root Explorer or something similar
  • Xperia Z1
  • Balls


Here's what you need to do.... (Version 2)
  1. Download this file http://bit.ly/1tR0Foc
  2. Flash in recovery
  3. Wipe Cache and Dalvik Cache
  4. Reboot

Now this should make the screen a little more comfortable in terms of swiping and typing. if you still get the issue please let me know.
C R E A T O R Of ThSEGA ICS
AND
RUSH Kernel
Kernel SEGA

Im no developer but I'm 100% sure this happen much more frequently when the device heats up. I play ppsspp and i can tell touch error will occur more when it heats up to a temperature. So this is most probably hardware problem. The higher the temperature the higher the electric resistance, right?

Taking off the plastic protector (if you got one) will reduce the problem a bit (because it's an insulator of electricity?)


So maybe what we have to do.... Maybe just automatically turn the screen sensitivity higher when the device heats up?

You know, I found a fix. Just turn screen off for a second with button and turn on. Just try it.

A crystal protector, like 9H Nillkin... This should reduce the screen sensibility, but I could't try it yet... Sorry for my english

I'm using Nillkin 9H, and I haven't had a single problem with my screen since I put it on. Before that I had the issues, so obviously working.

Got the Nillkin 9H glass protector also. Works well, feels smooth. It did slightly reduce the sensitivity, but it's minor. Make sure Pen Mode is disabled, because that gave me huge sensitivity problems.

Off-topic;

You should release a kernel instead, and finish what you started on the Xperia Arc / Arc S - your kernel work on ICS sources was top notch.
Android Devices that I am using:
1. Sony Xperia Z1 - ROM: iHackers v5.0 Beta / Kernel: TrinityUltimateKernelV2.4AC-Refreshed Stable Release
2. Sony Xperia Tablet Z - ROM: Stock 10.5.A.0.230 / Kernel: Stock kernel
