The new "Vatsab" update allows you to protect the user from sending a false message or listening to a message and regretting it.
According to LiveMint, the new update allows Vatsab the first time to listen to voice messages or listen to messages without opening the application.
Enabling this feature could not make the blue flag appear, which means that you heard the message through Vatsab.
This update is still available on the beta by WatSab, and will soon be available on the iOS operating system with iPhone phones, and later available on Android.
Watsab integrated the technology with the ability to listen to handset messages without having to listen to them by the loudspeakers.
