+    <!-- An array of (0: back camera / 1: front camera, approximate zoom ratio).
+     These values will be added to the lens switcher if one or more cameras uses the
+     multi-camera API to let the user select which lens to use. It's necessary to set
+     switch_in_zoom_level_supported to true. You also need to find the exact zoom
+     ratio needed to trigger the lens switch from your stock camera app and observing
+     the zoom ratio. Example for Google Pixel 4A 5G back camera configuration:
+         <string-array name="config_auxCameraZoomRatios">
+             <item>0:1.0</item>
