    Settings applied by ConfigProvisioner after installing this APK.
    ConfigProvisioner has WRITE_SECURE_SETTINGS and applies these as system.

    Tags:   <secure>   → Settings.Secure
            <system>   → Settings.System
            <global>   → Settings.Global

    Conditional blocks:
            <if [conditions...]>
                ... settings applied only when ALL conditions match ...
            </if>

    Condition attributes on <if> (all optional, AND logic):
        manufacturer="motorola"      exact match, case-insensitive (Build.MANUFACTURER)
        brand="motorola"             exact match, case-insensitive (Build.BRAND)
        model="razr"                 substring match, case-insensitive (Build.MODEL)
        sdk="35"                     exact Android API level
        sdk_min="31"                 minimum API level (inclusive)
        sdk_max="34"                 maximum API level (inclusive)
        form_factor="tablet"         tablet | phone | flip | tv
        feature="android.hardware.camera.flash"   any PackageManager feature string

    Nesting <if> inside <if> = AND (both must be true).
    Put separate <if> blocks at the same level for OR-like behaviour.
