[Android] Disable Display Size setting support

[Soap-141]

What would you like to be added

Might not be doable, made some research on it but it would be nice if we could ignore the display size setting on Android because it can mess up the UI quit a lot.

I guess the obvious fix would be to code better XAML with less fixes sizes and less range of sizes so there is no clipping and other weird behavior but sometime we have to do some workarounds or have fixed size / range of sizes that cause more issue when playing with this setting.

Default vs Larger with font scaling disabled.

Why is this needed

A flag to disable the display size scaling.

For which platform

Android

Anything else we need to know?

Thanks for the report.

There are those two properties that should be having an effect:

uno/src/Uno.UI/FeatureConfiguration.cs

Lines 197 to 203 in 669dbc7

	public static bool IgnoreTextScaleFactor { get; set; }
	#if __ANDROID__ || __IOS__
	/// <summary>
	/// Allows the user to limit the scale factor without having to ignore it.
	/// </summary>
	public static float? MaximumTextScaleFactor { get; set; }

But there may be cases where it does not apply properly.

Here is my sample SampleDisplaySize.zip @ajpinedam

I think we should both support the FeatureConfiguration properties properly, and also verify we accurately model how Windows handles text scaling based on accessibility settings:
