WhatsApp for Samsung Galaxy Z Fold 6

WhatsApp's official iOS-to-Android move only works during the very first setup of the phone, so if you already finished setup you'll need to factory reset the Fold 6 (Settings > General management > Reset > Factory data reset) to get the prompt again. During the Android setup wizard, choose to copy data from an iPhone, connect the iPhone with a USB-C cable, then scan the on-screen QR code with the iPhone's camera and follow the prompts in WhatsApp on the iPhone. Note that Samsung Smart Switch alone will not move WhatsApp chat history, so you must use this cable-and-QR WhatsApp flow specifically. See how others solved this on Reddit

WhatsApp can open in a phone-shaped letterboxed view, so force it wider with One UI's aspect ratio control: go to Settings > Display > Full screen apps and set WhatsApp to Full screen. You can also use the floating aspect-ratio icon that appears in the navigation bar or Recents when you switch to WhatsApp. After changing it, fully close and reopen WhatsApp, and make sure the app is updated from the Play Store since newer builds handle the larger foldable layout better.

This happens because WhatsApp renders the call in a phone aspect ratio and crops the wide inner display. First set WhatsApp to Full screen under Settings > Display > Full screen apps and then fully restart the app. If the image is still cropped, run video calls with the phone folded on the cover screen where the aspect ratio matches better, and keep WhatsApp updated since Meta has been improving foldable video-call scaling in recent releases.

The main quirks are cosmetic: WhatsApp may not always fill the inner screen and can briefly redraw when you fold or unfold, but both are addressed by setting it to Full screen under Settings > Display > Full screen apps. The bigger thing to plan is your chat transfer, which should be done during first-time setup using the official iPhone-to-Android cable-and-QR method, because doing it later requires a factory reset. Once moved, your messages, media, and groups carry over intact. See how others solved this on Reddit

For an Android-to-Android move, first back up on the old phone via WhatsApp > Settings > Chats > Chat backup to the same Google account you'll use on the Fold 6, then install WhatsApp on the Fold 6, verify the same number, and restore when prompted. Coming from an iPhone, the Google Drive backup won't restore, so you must instead use the cable-based iPhone-to-Android transfer during the Fold 6's initial setup, since that is the only path that preserves the full history.
