Multi touch not working

[Windows98Pro]

Hello, I have problem that multi-touch won't work.

I tried: 1: touch.scanPoint(): Returns 1 while touching (Multi-touch doesn't matter). 2:

for (int i = 0; i < 5; i++) {
  Serial.print(i);
  Serial.print(": ");
  Serial.print(touch.data[i].x);
  Serial.print(" ");
  Serial.print(touch.data[i].y);
  Serial.print(" ");
  Serial.print(touch.data[i].state);
  Serial.print(" ");
  Serial.print(touch.data[i].id);
  Serial.println();
}

Prints:

0: 469 246 6 2
1: 0 0 0 0
2: 0 0 0 0

Sometime touch.data[0].id will be 2 while multi-touching Aliexpress description says Support multi-touch, and I think this is not intended behavior.

I don't think this supports multi touch but still need to research more. The IC controller is called L58 and supposedly it comes from a mobile phone so it should work but I could never get so far more than one x, y coordinate pair on a single I2C read.
