— The blue sprite will fail to follow your finger if touch is failing. Move the finger across the screen to see the blue dot follow.
object count I can add, but it's not important, I'm only trying to detect if touch is failing or not.
I think your case is different from mine.
In my case (in my game) when I touch sometimes the touch is not detected but if I drag your finger at that time, then the touch is detected.
So if your example is to drag your finger, I see no fault there.
But if there is failure if you just touch the screen every time without dragging your finger.
You will notice that the blue dot sometimes does not respond to touch, here is the strange.
