WhatsApp has started rolling out its chat history transfer tool that lets you move your chat history between Android and iOS devices. Its first spotted on Samsung devices running on Android 10 and above, but WhatsApp plans to bring it to more Android devices "soon." The tool will let you import everything from voice memos, photos, videos to messages.
One of the notable requirements for the tool to work is that you'll need a Lightning to USB-C cable to connect the two phones. You also need to have the same number on both phones. Plus, your Samsung device has to be new or recently went through a factory reset. It would be best if you definitely were prepared before you access this tool.
