The Facebook announced that from 2021 it will no longer support the WhatsApp application on smartphones with versions prior to Android 4.0.3 and earlier than iOS 9.0.
The measure affects the entire line of iPhones 4 and earlier models
No caso dos iPhone 4S, 5, 5S, 5C, 6 e 6S, eles deverão ser atualizados para o iOS 9 para continuar a ter suporte ao aplicativo de mensagens.
Já o iPhone 6S, iPhone 6S Plus e iPhone SE é possível atualizar para o iOS 14.
No Android, usuários do HTC Desire, LG Optimus Black, Motorola Droid Razr e o Samsung Galaxy S2 perderão o suporte ao WhatsApp.
