Android Question Text Problem

[Guenter Becker]

Dear Sirs,
I have a B4A Projekt and set the manifest to show the Light Theme.
Running the project in Debug or Release mode on my Samsung S21 I allways get the text outlined. As shown in the title label and the buttons of a B4XDialog.
How can I avoid that outline to show text normal?

CreateResourceFromFile(Macro, Themes.LightTheme)
'End of default text.
'####################
SetApplicationAttribute(android:theme, "@style/LightTheme")
CreateResource(values, colors.xml,
<resources>
    <color name="actionbar">#ff039be5</color>
   <color name="statusbar">#ff006db3</color>
   <color name="textColorPrimary">#ffffffff</color>
   <color name="navigationBar">#ff006db3</color>
</resources>
)
CreateResource(values, theme.xml,
<resources>
    <style name="LightTheme" parent="@android:style/Theme.Material.Light">
        <item name="android:colorPrimary">@color/actionbar</item>
        <item name="android:colorPrimaryDark">@color/statusbar</item>
        <item name="android:textColorPrimary">@color/textColorPrimary</item>
        <item name="android:navigationBarColor">@color/navigationBar</item>
    </style>
</resources>
)

Check the device accessibility options. Maybe high contrast font is enabled?

What happens if you remove the custom theme?
