Prevent/Fix Touchscreen dead zones

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?

Is this a good question?

Hi @tryingtorepair ,

Tongue in cheek answer.

There is a 2 year manufacturer's warranty on the phone.

If the warranty is still valid for your phone and there is no obvious physical damage to the screen, contact the manufacturer regarding a repair or replacement.

Everyone knows if the warranty remains, one should contact the manufacturer to repair! BUT the question is IF the phone (device) is out of warranty, what to do?!

I have the same problem. The top side of the screen does not respond to touching and it was not repaired with ignitor either!

Any comment in this case is appreciated.

I just tried to do the lighter igniter fix and it did actually work. I don't know why though, or if it is potentially dangerous to the phone, but I could barely use it so I had nothing to lose. If anybody happens to want to try this fix I did it while the screen was on. One clic on the igniter and the screen is as good as new.

I have the same problem and wonder how the lighter igniter solutions is done. Do you only hold a lighter next to the phone and spin the igniter wheel so there is a small electronic discharge touching the phone? Should the phone be off or on?

I guess you should use and empty lightee to avoid a flame right?

I actually have just the igniter. I tear an emptied lighter and removed the igniter. It looks like a clicker with a small wire where the spark ignites. I carry it on me all the time as the fix sometimes only lasts a few hours.
