1. Run the attached project (or use any script that shows values of altitudeAngle and azimuthAngel variable of Input.GetTouch) on iOS and Android devices
2. Check what values of altitudeAngle and azimuthAngel variable are while you touch the screen of the devices

Actual result:
1. Input.GetTouch (i)..altitudeAngle is always 0 on iOS

2. Input.GetTouch (i).radiusVariance is always NAN on Android
Input.GetTouch (i).radiusVariance is always 0 on iOS
altitudeAngle of the 1st touch is 1.401298E-45, and 0 the rest touches on Android

3. Input.GetTouch (i) azimuthAngel is always 0 both on iOS and Android
