Google is refining its music identification capabilities on Android devices, with potential upgrades revealed through an APK teardown. Currently, users can identify songs using features like Circle to Search and Now Playing, but the process often requires manual prompts. The latest version of the Google app (build 16.12.39.sa.arm64) shows signs of automatic music detection, changing the interface to "Searching song..." upon recognition, although users still need to tap a button to view results. The absence of the typical pulsing-sphere visual element indicates that this feature is still in development.
