The following app is the ListView sample located here: http://developer.xamarin.com/samples/xamarin-forms/WorkingWithListview/
When using DynamicText in iOS, some text elements respect the change, while others do not.
### Steps to Reproduce
1. Download sample
2. on iPhone or iPhone Simulator, select General > Accessibility > Larger Text
3. Enable larger text and slide the size slider to max
4. Run sample app
5. Swap through the different tabs
### Expected Results
Either all text elements should respect DynamicText, or none should
### Actual Results
Elements are inconsistent in their DynamicText support

The built-in cell types (eg. TextCell) will adhere to iOS 8 DynamicText - this is demonstrated in the first tab of the example.
Custom cell types (or other text-display controls) should use the Style property with one of the Device.Style options set using DyanmicResource as explained here:
if they are intended to support iOS 8 DyamicText.
This has *not* been done throughout the sample mentioned - rather font sizes have been hardcoded with FontSize="Small" (for example) which explicitly overrides iOS 8 DynamicText. This is why the sample behaves with fixed font sizes on some screens.
To support iOS 8 DynamicText in the sample (or other Xamarin.Forms apps), first _remove_ any FontSize settings on the elements, and then _add_ a Style using DynamicResource syntax, referring to one of the built-in Device.Styles.
When dealing with a ListView control, it most likely requires HasUnevenRows=true to be set as well, so that the row height can grow automatically if the font size is enlarged.
