WT19i touch screen malfunctioning


I've bought WT19i recently and noticed the touch screen was not as responsive as it should be.

Post the Service Menu touchscreen service test (*#*#7378423#*#*), i'm sure its malfunctioning, please see attached screenshot of the test.


Test specifications for reproduction:

- I performed the test by swiping two fingers simultaneously vertically from bottom to top, only one will be detected and draw a line, this is the left line in the screenshot (quite understandable)

- next i removed the finger that was being detected, the control jumped to the other finger

- i dragged this finger from top to bottom vertically but the line kept spiking left horizontally across the screen as in the screenshot.

This is becoming a big problem, because the control keeping jumping all over the screen recording random key presses.

Forget being unable to play, i'm unable use the gesture input without typing random letters.
