Overview

• When a voice call goes unanswered, a new on-screen button offers to record a voice message alongside Call again and Cancel.
• The same "Record voice message" option also appears in the chat with the person who missed the call.
• WABetaInfo spotted the feature in WhatsApp for Android beta version 2.25.23.21.
• Availability is limited to some Android beta testers, and there is no sign of the feature in WhatsApp's iOS TestFlight.
• The test follows a separate missed-call reminders experiment, signaling a broader push on calling and voice tools.
