Unity and Android input touch?

Hello, I have a question about android devices and inputs. Currently I have a game for android that works without any input.touch. Right now all I’m using is Input.GetMouseButtonDown(0). For the devices I have personally tested this works fine.

Should I change this to Input.GetTouch and has any had any errors or big problems from this?

I have gotten crash reports from some devices about “ANR Input dispatching timed out (Waiting to send non-key event because the touched window has not finished processing certain” and then the error message ends. After disabling animations the crashes seem to stop. Does anyone have some ideas of what might be going on?

Thanks a bunch!

Use unity standard assets. they have a folder for mobile devices which contains prefabs for mobile touch
