I still don't see the problem, install AZ screen recorder > follow my test steps > start recording the screen when you test the touchscreen 

 

I don't understand what are we supposed to see on the video

 

You can also contact Sony directly >>> Local support

Re: TOUCH SCREEN PROBLEM, I REPRODUCED!

Based on his video, around 00:22, 4th row most right dot/line, he tapped it but not registered. However, the following tap register again. Then around 00:28, on the 7th row, it happened again.

 

I wonder if this issue only found on dual sim variant. Maybe can try a software repair via Xperia Companion.

Re: TOUCH SCREEN PROBLEM, I REPRODUCED!

Yes, you are right, I mean that is the phenomenon
the phone has been returned to sailer
Now I recall, the first day of the phone just seems to be no problem,
after upgrade the system, the next day I found the problem

 

Now I bought one again, because I still liked the phone

Re: TOUCH SCREEN PROBLEM, I REPRODUCED!

new phone arrived, 

also has problems,

 

i find a new method to test this problem

paint short line like this,

you do not to paint very fast, 

you could paint lines between a 1second interval, 

you will see, sometimes the line just painted doesn't display

and when you paint next line , the prev line displayed
