WhatsApp is going to improve voice messages.
Until now you have to hold the microphone button while recording.
In the future, you will see a lock icon that you can swipe up when recording. By doing this, the recording will be ‘locked’ and you will no longer have to hold the microphone button.
During the recording you can scroll through the chat. The function is currently hidden in iOS but is expected to be developed for other platforms as well. To be continued.
