My mobile app build with kendo ui failed user acceptance testing because the app is "slow", "sluggish" or "sometimes stops working". After some research I found out that the app quite often fails to react when the user clicks a button: the click event does not fire when the user does not tap "the right way". Since my app aims at inexperienced users, this is a serious issue.
The problem can easily be reproduced in the button/events demo, especially when viewed on a mobile device:
Just between touching and releasing move the finger or mouse a little bit to the side or up/down, and the click event does not fire.
What's worse (and why i would consider this an error) is that the user gets a visual feedback that the button was pressed --- but nothing happens!
It's kind of like the opposite of the problem in this thread: http://www.telerik.com/forums/button-click-event-firing-when-trying-to-scroll
where someone is (ab?)using oversized buttons.
Is there a way to set the sensibility of how much wiggle is allowed until a touch isn't a click anymore? Any other solution?
I am using kendoui.complete.2013.3.1119. The behaviour was tested on iOS6 & iOS 7 (iPad).
