hi

i am also having this issue. Is your led Innolux or truly? Can check by typing  *#*#7378423#*#* and see the ID of the panel.

It seems innolux have better sensitivity but Sony Customer Service stated only have panels of Truly..

Mine sent to warranty to change the LCD and still waiting (nearly a month).

My Xperia C5 Ultra dual have the same problm. I dont know why.

But when i hold my phone it's going normal again.

I too have the same problem. Another problem is that sometimes the touchscreen operates properly only if I use my thumb. If I use my fingers then the phone is not able to detect the touch properly and then starts misbehaving. Phone automatically opens an application on which I have never tapped.

Same problem here since the day i bought it. So disappointed with Sony.
