Sample to recreate the issue - OBSOLETE
I have a MasterDetail page, Detail is a Naviagtion page, Master contains a Listview. I'm changing the color of the header bar background color and text using
((NavigationPage)Detail).BarBackgroundColor = Color.Navy;
((NavigationPage)Detail).BarTextColor = Color.White;
This changes the carrier bar text to white for both the Master and Detail sections, but only changes the carrier bar background on the Detail section, the Master is still white/transparent so the text is no longer visible. I would expect the bar variables to work the same, to only work on the Navigation page since that is the page they are being applied to.
note- I am NOT setting the StatusBarStyle to LightContent, the status bar on a content page shows as black text on a white background.
I'm attempting to reproduce the behavior you're describing with the attached sample, but so far I'm not able to. When I run the sample, the carrier text remains black. In fact, I can't find any changes to the BarBackgroundColor or BarTextColor properties in the sample.
Can you provide an updated sample which demonstrates the issue?

Should be fixed in 2.3.4-pre1. Please note that this is an opt-in fix. Please see https://github.com/xamarin/Xamarin.Forms/pull/517 for an example of disabling this behavior. Thank you!
