WhatsApp is reportedly working on expanding multi-device support to smartphones and tablets. So, you could use the same WhatsApp account on a secondary phone. Also, the company is said to be bringing quick emoji reactions for status updates.
Till now, the multi device feature has been available to users under WhatsApp s opt-in beta testing programme. Now, according to WABetainfo, the update will roll out to iOS users this month, followed by an Android release next month.
