Nearly a month after announcing chat history transfers from iOS to Android, WhatsApp has also confirmed Android to iOS transfers. According to WABetaInfo, the feature is still in development and will be made available in an update at an unspecified time in the future.
The details of how to transfer your WhatsApp chat history from Android to iOS are also a mystery at this point. Both WABInfo and 9to5Google believe that the Move to iOS app will be a key part of the process.
Furthermore, India Today reports that WhatsApp will be dropping support for older smartphone operating systems. Android 4.0. 4 (Ice Cream Sandwich), iOS 9 and anything older will be dropped starting in November. Android 4.1 and iOS 10 or later will continue to be supported.
