WhatsApp plans to cease supporting a handful of older mobile operating systems by the end of the year.
WhatsApp will stop working on devices running Android 2.1 and 2.2; all BlackBerry OSes, including BlackBerry 10; Nokia’s S40 and Symbian S60 platforms; and Windows Phone 7.1.
“While these mobile devices have been an important part of our story, they don’t offer the kind of capabilities we need to expand our app’s features in the future,” explained WhatsApp in a blog post.
WhatsApp suggests people relying on devices that run this operating systems upgrade to newer hardware if they wish to continue using WhatsApp.
Facebook bought WhatsApp in 2014 for $16 billion. Facebook says WhatsApp has more than 1 billion users worldwide.
