Buttons aren't always responsive with Touch on mobile

Question

I have found that the the buttons are not always responsive to touch on mobile devices.  I have tested with two separate projects built to Android, tested on a number of devices including Samsung S7.

The ripple effect always displays when touched but the click event on the button does not always fire.

This occurs on normal screens, tab buttons, nav drawers and a number of other elements.

It ruins the user experience and makes the app unusable at times.

Answer 1

OK, my bad.  After a few hours of banging my head and Googling I have solved it.

I was missing the EventSystem in the canvas and once I set the Drag Threshold up then it works as expected.

Thank you for posting this. I modified the drag threshold from 5 to 10 and it works great.
