WhatsApp seems to be working on multi-phone and tablet chatting

WhatsApp seems to be working on a feature that would let users chat with the same account on multiple phones, or on a phone and a tablet, according to a screen found in a beta version of the app by the site WABetaInfo. The screen gives instructions for registering the device you’re using as a “companion” by scanning a code with your main phone — though currently there doesn’t appear to be an actual code to scan.
