Once users agree to the cloud data transfer, they will be taken to a browser-based permissions page where they need to select the “Transfer a copy of your data” option. It appears that Google’s app is still a work in progress, as there are some features that aren’t functional at this point in time. As spotted by 9to5Google, when the app is first launched on an iPhone, it shows the prompt to scan a QR code from an Android phone, but that doesn’t appear to be working in its current state. The QR code system is likely there for creating a hotspot that connects the two phones wirelessly.
Beyond that, the app is still missing two crucial elements: the ability to transfer messages and apps from an iPhone to an Android phone. The latter makes sense due to platform restrictions, but in the process, users also risk losing all the cached data associated with an app if they have to re-install them on an Android device — and, of course, there’s the cumbersome job of signing in for a majority of them. As for the disabling iMessage part, this ensures that if a message arrives during the transfer process, it doesn’t get lost. Google hasn’t updated its official Switch to Android website to include the app, and there is no information regarding a public launch, which will, presumably, happen after the company irons out all of its shortcomings.
