Disable multi touch

Is it possible to disable multi touch gesture In ionic 2?
I am currently using ‘touch-start’ event on my drawing app, and would like to disable multi touch while drawing.

It’s a question I’ve been searching for a long time but it seems nobody cares…

It happens with menus, slides, back from another views (iOS), an so on…

It no professional at all. It seems like the app is broken with that behavior.

Any suggestion here?
