After upgrading my project to Unity 5, I’ve noticed the Touch.deltaPosition gives odd results on Android devices. Basically, many times it is reset to zero on many update loops which is wrong. And I’ve also noticed that values tend to be more accurate as touches approach the center of the device’s screen.
A question has been posted in the answers section about the issue: Touch.deltaPosition giving jerky movement on Android in Unity 5 - Questions & Answers - Unity Discussions
It’s worth mentioning here that the same code worked fine on Unity 4.6.
Has anyone experienced this issue?
