If you reinstall WhatsApp or buy a new iPhone:

🤖 Can you transfer WhatsApp from iPhone to Android?
Yes! WhatsApp has an official tool to migrate your chats:
- Connect both phones (iPhone and Android).
- Follow the steps in the transfer assistant.
- Wait for the process to complete (it may take a while).
