Once users have agreed to the data transfer to the cloud, they will be redirected to a browser-based permissions page where they will need to select the “Transfer a copy of your data” option. It looks like Google’s app is still under development, as some features aren’t working at this time. As spotted by 9to5Google, when the app is first launched on an iPhone, it displays the prompt to scan a QR code from an Android phone, but that doesn’t seem to work in its current state. The QR code system is probably there to create a hotspot that connects the two phones wirelessly.
Beyond that, the app still lacks 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 cached data associated with an app if they have to reinstall it on an Android device – and, of course , there is the tedious signing work for the majority of them. As for the deactivation part of iMessage, it 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’s no information about a public launch, which will likely happen after the company fixes all its shortcomings.
