The latest WhatsApp beta for Android brings a few changes in the user interface.
The textfield has rounded corners and includes the paperclip (attachment-icon) and a camera icon. The camera icon, a shortcut for making pictures and videos, disappears when you start typing.
On top of screen, you can now start a call or videocall directly.
It’s not known yet when the new user interface will be brought to the ‘normal’ version in Google Play.
