Two finger side by side and close touch that would become one point

Test method:
Open "Sketch - Draw & Paint" app by sony.
Two finger side by side and close touch and move.
It would draw a line in XZP. Normal action should move canvas.

It would cause bad game experience like below CGSS test:

Recently I found an touch screen issue whitch really bothers me when I playing the following music game.

アイドルマスター シンデレラガールズ スターライトステージ

You can see this issue in the video link below.

Touch issue when playing アイドルマスター シンデレラガールズ スターライトステージ

As you see in this video, two touch points will be justify as one point when they are close.

It caused bad gaming experience in other music games too.

To easily reproduce this issue, you can follow the steps below

1, open phone apps and input *#*#7378423#*#* 

2, Service tsets => Touch => Free Drawing test

3, Put two fingers on the top corner of the screen

4, start to draw as the picture below.

This issue has been noticed in following topic, but didn't get any response.

It obviously an issue related to touch firmware. 

Hope sony could work with touch ic vendor to deal with this issue.
