Delay before first touch position changes on iPhone -

i have problem using input.touches[0].position on unity3d. sorry if problem unclear, find hard describe.

when start touching screen , start move finger position returned input.touches[0].position doesn't change immediatly, have move little jumps current touch position.

this happens on iphone, don't have other touch devices.

here testable code illustrating it:

using system; using unityengine;  // attach game object on scene public class testtouch : monobehaviour {     private void update()     {         if (input.touchcount == 1)         {             // have add guitext component gameobject             this.guitext.text = "pos: " + input.touches[0].position;         }     } } 

i think problem cased early-gesture detection process.i'm not sure if solve question please try this:

if (input.touchcount > 0 && input.gettouch(0).phase == touchphase.stationary) {     // sth. }
