Since there's no thread about fixing this here in Z1's forum, I'd make one with possible fix on the crazy touch screen problem.

As far as I know, this is a firmware-related problem, and can be fixed by tweaking down the touch screen sensitivity. You'll need
to be rooted to use this modification. Always remember, try at your own risk, and don't forget to hit thanks button if I helped!!

HOWTO:
1. Take a backup with CWM or TWRP.
2. Use any root explorer that you like, and navigate to /system/usr/idc/.
3. Copy the file "clearpad.idc" to somewhere else, like the SDcard storage for editing.
4. Open up the file with Jota+ or the text editor of your choice, and find the line "touch.filter.level". By default it would be 2, but
here I would suggest a value of either 5 or 6 for lowered sensitivity.
Code:
touch.filter.level=6
5.Save the file and then mount /system as writable.
Code:
mount -o remount,rw /system /system
6. Paste the modified clearpad.idc back to /system/usr/idc/ and set correct permissions.
Code:
cp clearpad.idc /system/usr/idc/ && chmod 644 /system/usr/idc/clearpad.idc
7. Remount /system as read-only and reboot.
Code:
mount -o remount,ro /system /system && reboot
Well, this worked for me, and as I know there are lots of people out there irritated by this problem, this should provide a proper
method for restoring the functionality for their Z1's. Now a greasy screen and slight moisture would not upset the touch screen unlike before.

p.s. I'm on NUT's .290 with C6903. This should also work for other models and Android versions.

Ive got the problem too with no AFS on the phone ://

Currently, Im able to solve the problem by wiping the phone for like 10secs with my tshirt. After that the touchscreen ALWAYS works flawlessly for like 5 mins. Im going to buy a new protector tomorrow and hope that that is going to fix this issue!

Hi everybody!

For me, if i turn off the screen (only with the power button, nothing more), the problem fix during some time (sometimes 5 minutes, sometimes hours).

I have the latest stock version, locked bootloader and rooted. Xperia Z1 C6093.

i think the many problem with the touch screen is by taking of the asf that sony puts on these phones. i took it of 2 days ago and since then it was always doing strange touchscreen things like making selections out of it's own or thinking there where 2 fingers on the screen.
