A 5mm vertical row of my FP2 touchscreen doesn`t respond to touch Inputs.

Prevention:

-You should try to avoid tensional stress of the phone (eg. phone in pocket while cycling).

-Also heat could have caused this problem, which my phone was exposed to when the problem occured.

Fix?

I heard that the problem could be (temporarily) fixed using an electrostatic discharge from a lighter igniter.

Why should this work? Is it influencing the static potential of that area, since it is a capacitive touchscreen?

Has anyone damaged his phone due to the high Voltage and electric field?

Are there other solutions without replacing the whole screen?
