Updated emoji comes with update to the WhatsApp beta for BlackBerry 10
An issue with the app caused media transfers to fail if the app was closed before the transfer was completed. This problem has been resolved by the update. And of course, the proverbial bug fixes and performance enhancements are included with the update. Speaking of bugs, since this is a beta version of the app, you might find some minor issues with it.
It might have escaped your memory, but Facebook purchased WhatsApp, closing on the transaction back in October 2014. The final purchase price was $21.8 billion. BlackBerry users, of course, have their own home grown multi-platform messaging app in BBM.
