Google is said to be planning to introduce a new Android feature that will allow users to link their different Android devices together, similar to Continuity features across the Apple ecosystem.
Android expert Mishaal Rahman tweeted about the potential feature, noting that it could allow Android devices that are signed into the same Google account to communicate with each other.
This could enable features such as Call Switching, which allows users to switch between connected devices during calls, and Internet Sharing, which the Android Authority speculates could be an easier way to quickly set up a Personal Hotspot across linked devices. Similar calls are called "iPhone Mobile Calls" that allow users to make and receive calls from Apple devices such as Macs and iPads that are signed into the same Apple ID, provided they are on the same network as the user's iPhone.
However, Android Authority also notes that Apple's "iPhone Mobile Calls" feature does not allow users to receive calls from another iPhone.
And the wording of Google's "Call Switching" feature indicates that it can be used to switch between different Android devices, including phones. So you might be able to answer a call on the phone and transfer it to another linked phone or something like a Pixel Tablet. We won't know for sure until Google officially announces it, but if it's original, it could be useful for people who need to carry more than one phone around.
Rahman claims that the Link Your Devices menu will appear under Settings > Google > Devices and Sharing in Device Settings once the feature is officially launched. Google has yet to announce an Android Device Link feature, let alone a release date.
