Hi!
I'm facing too the issue described by agarwalyashash.
In particular I've noticed that touching an object trigger the "click" and "touchstart" events on my iframe.
But the workaround suggested doesn't fix the problem to me.
This occur only on Chrome for Android and Native Android Browser.
Safari works fine.
I tried disable "Use mouse input" option but it doesn't solve the issue :(
I'm working with Construct2 r255.
Do you have any other guess??
Let me known if other info is needed.
Thank you!!
