Issue Description: On both my Samsung Galaxy S25 Ultra and S26 Ultra, when using Galaxy Buds 3 Pro, the AI-based voice isolation works perfectly during GSM calls and WhatsApp calls. However, it completely fails during WhatsApp voice note recordings.
During voice note recording, all environmental noise (road noise, air conditioning, background sounds) is captured with no suppression, as if Voice Focus is not applied at all, despite being enabled. Technical Observation: This strongly indicates a Bluetooth profile handling issue: Voice isolation works correctly in Call mode (HFP/HSP) Fails in Multimedia/recording mode (A2DP or related input path) used by WhatsApp voice notes It appears that AI voice isolation is not applied when the Buds operate outside call mode, which points to a system-level limitation or bug.
Troubleshooting Performed (Exhaustive): I have already performed all possible standard and advanced troubleshooting steps, including: Updating Galaxy Buds firmware, Galaxy Wearable app, and phone software to the latest versions Restarting both devices and reconnecting from scratch Fully resetting the earbuds via Galaxy Wearable Re-pairing the earbuds multiple times Testing on two separate devices (S25 Ultra & S26 Ultra) with identical results The issue persists consistently across devices, confirming this is not device-specific and not due to user configuration.
Conclusion: Given that: The feature works correctly in calls The issue is reproducible across multiple flagship devices All troubleshooting steps have been exhausted This is very likely a software limitation or bug related to Bluetooth profile switching and audio processing paths.
Thank you for your detailed feedback, and we appreciate the effort you’ve taken to investigate the issue.
Based on your description, the behavior is related to how certain third-party apps like WhatsApp handle audio input during voice note recordings, which may differ from call scenarios. In some cases, features like noise cancellation or voice isolation may not be fully supported outside call mode due to app or system limitations.
We recommend ensuring all related apps and software are updated to the latest versions. Additionally, sharing feedback directly through the Samsung Members app (Get Help > Send Feedback) helps the concerned team further analyze such cases.
Your feedback has been noted and will be shared with the relevant team for review.
