Reproduction steps:
1) Open Unity Remote on a device
2) Open "case_815918-DeltaPositionBug.zip" project
3) Open "scene" and enter playmode
4) Swipe on screen using Unity Remote and check results in console output
5) Exit playmode and build game for Android device
6) Swipe on built project and check debug output in adb logcat
- Notice that user's calculated delta position in built project is very different than in case using Unity Remote

Note:
User's formula for delta position: touch.position - LastPosition // last position is updated in LateUpdate()
