You are doing fine with your English, no need to say sorry.

I don't quite understand what is happening or what the problem is. Can you try to explain a little?

[0908721000]

I have problem with touch screen (video uploaded) problem only with phone app when calling ( auto loudspeaker, mute micro, dialpad, press many number on dialpad...) I have tried factory reset on my phone and xperia Component...) But can't resolve this problem

[nathanhorner]

Ok so when you use the phone app it is mysteriously press buttons all over the place all by itself? Like a ghost in the screen?

[0908721000]

Exactly!

I have try disabled double tap to walk temporary fix this problem. I will be feedback this problem again

[0908721000]

Do you have glove mode (settings->display->scroll to the bottom) switched on?

Is it specific for that 1800 number or does it happen with all phone numbers.

Does it happen in safe mode too?

[0908721000]

I don't use gloves mode. I tried safe mode and reset all with xperia component.

This problem with all calling all number. But another application use normal.
