WhatsApp announced in a note of support for its users that from the first day of the year some features of the app would stop working for certain cell phones.
The messaging system noted that its app would no longer be compatible with Android operating systems (versions before 2.3.3), Windows Phone 7, iOS 6 and Nokia Symbian S60.
Also, users of BlackBerry OS, BlackBerry 10, Windows 8 (and previous versions), Nokia S40 and Android 2.3.7 (and previous versions) will no longer be able to create new accounts or reverify those currently activated.
WhatsApp had already announced its intention to end its support for these operating systems because BlackBerry, Nokia and Windows are no longer the most popular operating systems in the world. Instead, the one unit of Facebook will focus on improving its support for Android and iOS.
“These platforms do not have the capacity we need to expand the features of our app in the future,” the company said. WhatsApp warns that there will be no option to transfer the chat history of these old operating systems.
