@WhatsApp there are similar cases in Samsung One UI as well. After calls/recording voice messages WhatsApp keeps using microphone in background, which can only be stopped by revoking the app's microphone access.
Seems like a bug with WhatsApp itself, rather than mis-attribution.
Over the last 24 hours weโve been in touch with a Twitter engineer who posted an issue with his Pixel phone and WhatsApp.
We believe this is a bug on Android that mis-attributes information in their Privacy Dashboard and have asked Google to investigate and remediate.
