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. This was a tough decision for us to make, but the right one in order to give people better ways to keep in touch with friends, family, and loved ones using WhatsApp," WhatsApp said in a statement.
