This issue is stopping us from releasing our app so I've created a sample Forms project to demonstrate the problem and hopefully someone can help.
Just to note - this is also the same using Xamarin.Mobile but as I understand it, XLabs is a fork of Xamarin,Mobile (don't quote me on that I just remember reading it somewhere) and hence I think that's why we get the same results.
It's a simple project attached which just tries to record a video - but in Android it won't work - it doesn't crash, it just doesn't complete the recording or give you an option to use what you've recorded. It's very strange but I'm absolutely sure this was working a couple of months ago.
Any help is appreciated, I know the code must work because on iOS it works correctly so it's quite difficult to get to the bottom of.
