Crazy touchscreen after Marshmellow update xperia z3 - Yet, another issue!

[Thunderps2]

Hello friends , I'm from Brazil . 
Recently I updated the Z3 to the latest version of Android (since, for reasons ' business , we will not 7.0 ) 
and after a few days , the touch screen is crazy . I noticed that this occurs in a piece in the middle of the screen.

I tried several hard resets , PC Companion software repairs and nothing . 
I sent the smartphone to the local service , and how it is out of warranty , 
ended up charging me the price of a new product to make the repair. Too much expensive!

However, they did not issue a technical report , only the price of work to be done .
I refused to pay and they returned the phone. 
Apparently , z3 came formatted and without problems , but .. 
when I realized a usb charge, plug charge, etc , the issue returned not disappeared even after several formats . 
Any idea?

Sorry for my bad english.

Hi @Thunderps2,

I'm sorry to hear about your phone.

To me this sounds more related to hardware than software the way you describe it, if you have performed a software repair using Xperia Companion and it didn't help I'd recommend that you send your phone to an authorized service centre. Contact your Local support for information on how to send it in.
