I'm not sure if this is a Syncfusion or XF problem, but the problem started occurring after the XF 3.5 update. I suspect it's related to the SfListview control, but I can't be sure. I have created a very stripped down version of my app and I'm able to replicate the problem.
Visual Studio 15.9.7
Xamarin Forms 188.8.131.52047
My Xamarin app uses .net standard as it's code sharing strategy
Issue happens on Android and iOS builds in release mode
Issue can be reproduced with a small representative app on Android (haven't tried yet on iOS)
Here is the XAML for the MainPage of my basic app:
