The Material Design which broke cover with Android Lollipop seems to be catching up at a brisk pace with apps. WhatsApp recently got itself the Material Design update and now BBM for Android has got itself the Material Design. The revamped UI is being rolled out currently to a select few BBM for Android users and you may soon get the notification for the update in near future.
The update brings large contact images, bright colours and an interface that is consistent across the app. BlackBerry claims to have worked quite hard on bringing the latest UI design to its messenger. The newer version of BBM for Android is available only through BlackBerry Beta Zone which is meant for the registered ones only. BlackBerry wants to have a measure of customer response before going in for the final rollout and is doing exactly this.
Currently, the beta program is full with registered members and your best shot at trying the revamped version is through joining the wait list for the time being. There is no official word as to when the update will see a final release and we can expect it to launch within the next 4-6 weeks.
