Will My WhatsApp Messages Transfer with Smart Switch

Smart Switch allows you to transfer most data from an old device to a new one. However, certain data cannot be transferred such as but not limited to read-only contacts, emergency alerts, temporary messages, failed to send messages, calendar from synced accounts, chat history or some other data protected by 3rd-party provider's policy, encrypted or DRM (Digital Rights Management)-protected media file or personal app data, wallpaper (pre-installed and Galaxy Themes).

To share your messenger application data, you must remember to back up the data and update the applications to the most recent version.
