After it was announced that CarouselPage will be deprecated I refactored my App to CarouselPage just to find out that it has some serious problems on Android like 


But if you use it like me as a Fullpage CarouselPage replacement with a ListView embedded it's hardly usable at all.

Just build the attached Project and deploy it to any Android Device.

When you try to scroll the ListView most of the time the Carousel will start turning so that you cannot scroll the listview without accidently change the page.

On iOS this works fine depending on your direction when you first strike the screen.

Please do something about this!

+1. I'd given feedback on the forum related to this, but here it is again:

Tested it on Android:

"When you create a carousel of listviews, listview scrolling seems messed up. Any slight right/left swipe will cancel listview scroll. I think there should be a way to set swipe tolerance so carouselview does not wake up.

Also, if you stop swiping the carousel between two positions, it will crash the app.

Finally, the carousel doesn't seem to snap back into the original position if you don't swipe long enough."

Still appears to be occurring with pre2.
