Implemented and potential features
“Verified” below means the owner exercised the control on a physical MX-T40, with packet reports or direct observation. It does not establish compatibility with other Samsung models.

Next work
Keep the working transport stable. Add read-only status decoding before new controls, then validate one feature at a time on hardware. DJ effects are a useful next feature because the app contains both effect selection and level commands. Grouping is more involved because it changes relationships between speakers and needs more than one device for testing.
The firmware XML is a Qualcomm configuration schema, not a dump of configured values or a Samsung command dictionary. It documents audio routing/gain curves, button/LED patterns, codec-related definitions, power policies, and GAIA fields. Listed schema options do not prove those features are enabled on the MX-T40.
