In the past, switching to a new phone meant that you would lose most of your local data. Over time, as long as you stay in the same ecosystem, it will be easier to transfer files, settings, and contacts. For example, if you buy a new Android phone, then the online Google Drive backup will automatically restore your WhatsApp conversations and media. However, if you decide to buy an iPhone, there is no official way to restore conversations and media from an Android phone. According to reports, WhatsApp is working to resolve this warning, thanks to a native solution that can automatically transfer chat history between platforms.
WhatsApp is working hard to allow users to use the same number to chat from various devices, it is no secret. Although it is not clear how to deploy this feature, it does make sense for WhatsApp to also allow cross-platform backups. In fact, whether you use various devices at the same time or simply switch from one device to another, you should coordinate the structure of cross-device access and synchronization conversations.
The feature is not yet available, but the new vulnerability indicates that users will be allowed to migrate their chat history from iOS to Android and vice versa. According to the screenshot above, the process does not appear to be performed automatically, and may have to be triggered manually to initiate the transfer.
It must be kept in mind that this feature has not yet been implemented, so it may be different when it is officially released.
