By which users link their WhatsApp account from their smartphone to the platform's Android tablet app. It means there is no need to create a separate WhatsApp account on the secondary Android device. WABetaInfo report further corroborated the new feature, which is said to be working on WhatsApp beta for Android with a 2.22.25.8 version number. Both reports imply that the said WhatsApp beta testers will be able to see a new banner on top of the chats asking users, "Have an Android tablet?".
Tapping on banner as like Android tablet would take you to a 'Link with your phone' tab, which is a pretty familiar page for WhatsApp Web or WhatsApp Desktop Client users who often connect their smartphones regularly. Which further allows scanning a QR code, again quite a similar process with the Web and Desktop clients. After scanning the code, the chats and media are said to be transferred from your Android phone to the linked Android tablet.
This feature helps Whatsapp on Android smartphones and tablets simultaneously. While the desktop clients are already user-friendly for PCs.
