Strange problem with touchscreen

FederalBureauFB — Sat, 23 Apr 2016 09:14:14 GMT

Hello, guys.
Recently, I dropped my M2 on the street, resulting in cracked touchscreen and lcd. Replaced both the touch and the lcd, everything seemed normal until I noticed that the middle part of the touch (a line going from the left to the right, around 1cm height) doesn't work, it just doesn't respond. Later, I got another new touchscreen and same story - same part of the screen doesn't work.

Maybe we have some kind of defect touch screens here in Bulgarian stores? Though I bought the two touches from two seperate stores. Or it's possible that it's something with the lcd? Even though it works normally, no strange behavior, no black spots, scratches or anything. Or could it be a software problem?

Thanks in advance.

Hi, thanks for your answer.

Sadly, it wasn't repaired in a service center.

Something I forgot to mention is that when testing the screen in Sony's Sketch app or in the service menu, if I run my finger from the top to the bottom, or the opposite way quickly enough, the lines my finger makes don't get cut, i.e. it's like the screen is functioning properly, with no dead spots. What could this mean?

Also, I wrote to Sony support, and from what I understood, their answer was that it could be some kind of a compatibility issue between the phone/touchscreen/LCD.

I'm almost sure touchscreens aren't the problem (excluding the compatibility thing), considering this "dead" area is a smooth line going from the left to the right, not like some random scratches, also it's located on the same place on both screens.
