WhatsApp launched a new beta on Android that includes an important feature that allows hands-free recording of voice notes in applications.
After the update is installed, when the user presses the microphone button to record audio, another option appears on the screen and you can swipe up to lock the recording. When done, the app will continue to record voice notes without having to hold down the microphone button. You can still cancel the recording and delete the file without sending it.
To use the lock recording feature on your Android device, you need to download the beta version of WhatsApp version 2.18.102 for Android. This applies to beta testers on Google Play. Or you can visit APK Mirror to download the APK file and download the same file on your device.
