UIButton intermittenly not receiving click

[CoachCarter9]

Hello,

I'm using NGUI 3.9.8 and I have a set of buttons that seem to require multiple presses to fire OnClick. It's very infrequent in Editor but occurs frequently on my iPhone SE. I've included a screenshot of how the buttons is setup. Any help would be great!

Touch events on mobile devices are very imprecise. It's quite possible that the way you press on the screen causes a drag event to fire, which effectively cancels the click event. Check your UICamera -- drag thresholds are specified on it.

Hey Aren,

Thanks for the reply! I adjusted the touch drag both higher and lower and with no luck resolving the issue.

Fwiw, it seems to be only a particular button suffering this issue but I personally can't see anything that would be the cause of it.

is there possibly an extra collider that is blocking the event?

Or perhaps the button is so small that a touch event moves off of it easily. Mobile device buttons generally need to be rather large.
