WhatsApp will soon allow users to link their accounts to a secondary phone or tablet, as we learned earlier in April. Companion Mode was the name of the feature at the time, and it is currently accessible for certain Android users with the most recent beta release.
The WhatsApp beta for Android 22.214.171.124 offers the Companion mode to selected beta testers, according to the reliable source WABetaInfo. Currently, using the functionality only requires you to scan a QR code in order to connect your WhatsApp account to an Android tablet. You cannot currently connect your account to a second smartphone, though.
Some WhatsApp users can now finally access companion mode by going to the Linked Devices area in WhatsApp Settings and scanning the QR code that will be displayed on your tablet, you can try the feature if you are using the most recent WhatsApp beta release. As long as your tablet has an active internet connection, your WhatsApp messages should sync to it.
Once the syncing is complete, WhatsApp will work on your tablet even if your phone doesn’t have an active internet connection. What’s remarkable about this situation is that you can connect a WhatsApp account on an iPhone with an Android tablet using this version of Companion mode.
The Companion mode is currently being developed, therefore certain functions might not function properly. According to WABetaInfo, you might not be able to view live communities and locations on a companion device, but accessibility will improve once the feature begins to roll out into stable channels.
The Companion mode, which enables the user to use the same WhatsApp account on two phones, will likely be expanded by WhatsApp to include more Android smartphones. We do not, however, currently know with certainty when that will happen.
