WhatsApp gets option to lock voice message recording: Here is how it works
Earlier for voice recording a user had to hold the mic button record, and then slide to send the message. With the voice recording lock, it makes things a lot easier and simpler. While we could see the feature on the Android beta version, the iOS version of the app did not reflect the voice recording lock option for us yet.
WhatsApp Android beta testers need to be on version 2.18.102 or higher for the feature to appear. WhatsApp users can sign up to be beta testers from the Google Play Store itself. Just go to WhatsApp’s page on the Google Play Store. Scroll down to the bottom and you will see an option for signing up to be a beta tester. Click on yes, and you will be enrolled in the beta program. It can take some time for the beta approval to appear. Users also have the option of leaving the Android beta program.
