hello all again
I think i solved my issue. I found out another topic in another Xperia phone forum. That phone's users problem was undersensitive touch screen , so i did opposite of what they did
I went to /system/usr/idc but not modified the file max something.
I modified clearpad.idc file. The value touch.pressure.scale was 0.0075 something. I changed it to 1
now the touchscreen is less responsive and nearly no ghost clicks anymore.
Hope this helps anybody have this issue.
