Google is developing a new feature for its Phone app that includes an "Unhold" shortcut in call notifications. This button will replace the existing "Mute" option when a call is placed on hold, allowing users to resume calls directly from the notification shade without returning to the main call screen. The feature is part of a Material 3 Expressive redesign and is currently available in beta version v184.0, although it has not yet been released to the public.
