Facebook-owned WhatsApp has rolled out a new update for its Android app. Bearing version number 2.17.146, the update introduces some user interface changes to the app.

After the update, WhatsApp’s Android app has a separate button for video calling. The placement of the attachment button has also been changed. A new video calling button is placed next to the voice calling button, on the top left corner of the upper bar.

The attachment button now sits next to the camera icon in the text bar. Moreover, the shape of the text input field has been tweaked. It now has rounded corners instead of being rectangular in shape.

Recently, an online report suggested that WhatsApp will soon introduce a new feature that’ll enable users to pin individual or group chats. The chat-pinning feature is available in WhatsApp for Android’s beta version 2.17.162 or 2.17.163.

The feature allows users to select up to three chats (including individual or group chats) on top of the list, so that they don’t get lost. To pin a chat, users can long press on it and tap on the pin icon seen on the top bar. The icon is accompanied by other icons which can be used to access other options such as delete, mute or archive.

The same method can also be used to unpin chats. Users will need to long press on the chat once again and tap the pin icon on the top to unpin it.
