Sharing is caring!

WhatsApp is one of the most used messaging applications for mobile devices. The application is available for multiple mobile operating systems and it comes with a lot of features. Unfortunately, Voice Calling – one of the most awesome features it comes with it is available only for smartphones that run on Android, BlackBerry 10, Windows Phone or iOS.

According to the latest rumors, the WhatsApp version for the mentioned mobile operating systems will also receive a Voice Calling feature sometime in the near future. However, this was not confirmed by the developers of WhatsApp, so we should take the news with a bit of salt.

Today we will talk about WhatsApp 2.12.402 which is the latest BETA version of this application for Android devices. This new update doesn’t come with new features, but we’ve noticed that the APK (installation) file has been increased by 198KB.

The new WhatsApp version comes with 219 modified files and it seems that the thumbnails file has been removed. It is good to know that some of the new files are related to the share documents function.

WhatsApp 2.12.402 BETA: How To Install On Your Android Device

The WhatsApp 2.12.402 is currently in BETA, which means that you will not be able to find this version on the Google Play Store. However, you will be able to download the WhatsApp 2.12.402 APK (installation) file from the internet and manually install it on your Android device.

Before you do this, you will also need to enable the “Unknown Sources” option. This option will allow you to install APK files that have been downloaded from a third party source. This option can be found in your Android device’s Settings->Security or Settings->Applications (it depends from an Android OS version to another).

Once you have enabled the “Unknown Sources” option, open the browser on your Android device and head to and tap on the “Download Now” button to start downloading the latest WhatsApp BETA version to your smartphone. Once the download is complete, use a file manager application to get to the location where you’ve saved the APK file and tap on it to start installing the latest WhatsApp BETA version on your Android device.
