I created a blank app, I wrote the following code in MainPage.xaml:
<Label Text="Welcome to Xamarin Forms!"
VerticalOptions="Center" HorizontalTextAlignment="Center"
LineBreakMode="MiddleTruncation" />
<Button x:Name="btn" BorderColor="Teal"
Clicked="OnButtonClicked" HorizontalOptions="Center" Text="Test Click me" />
Then runs it, and there is an odd thing in the Android. The Label text shows right, but the button shows in uppercase letters "TEST CLICK ME". And I clicked the button let it shows its text property, it shows “Test Click me”.
Why is that?
