+## FAQs
+### Can I use the catalog of device-mode destinations from Analytics-Android?
+No, only the plugins listed above are supported in device-mode for Analytics-Kotlin.
+### Will I still see device-mode integrations listed as `false` in the integrations object?
+When you successfully package a plugin in device-mode, you will no longer see the integration listed as `false` in the integrations object for a Segment event. This logic is now packaged in the event metadata, and is not surfaced in the Segment debugger.
