I would like to suggest a feature for GrapheneOS: an aditional option to block microphone access for all apps except during regular phone voice calls. This would be very useful for users who want to keep the microphone disabled most of the time for privacy reasons, without having to manually enable it whenever making or receiving a phone call. I think this would fit very well with GrapheneOS’s privacy-focused and granular control approach.
Thank you for considering it. Best regards.
