WhatsApp for Android now fully employs Material Design; Holo, begone!
All of these are a thing of the past now, as version 2.12.84 of the app now officially allows each and every WhatsApp user with a 'Droid handset to experience the refreshed design of the messenger app. It's streamlined and a bit more organized than the very first version that commanded the refreshed looks. Unfortunately, it still comes with a few archaic Gingerbread icons here or there.
Luckily, a new beta version of the WhatsApp (2.12.87) polishes the user interface and gets rid of these. It also extends the reach of Material Design even further by overhauling the in-call interface, putting a subtler wallpaper in chat conversations, and now even supports the new diverse iOS emojis that arrived with the latest rendition of Apple's mobile OS.
You can get the latest official version (2.12.84) from the link right below; for the more refined beta (2.12.87), go here.
