The hectic work of WhatsApp developers never stops. In fact, here we are with the fourth update in a week of the Android version of this popular instant messaging application. This new 2.12.419 Beta version of WhatsApp for Android has been released today with the usual bug fixes and it seems also that the app is getting much more stable.

So, is this the only reason for this last release? It seems so, considering that this new 2.12.419 doesn’t bring any new features. Or at least that’s what appear at a first glance, even if it seems that some changes have been done on the translation to certain languages.

The 2.12.419 APK (installation) file weighs 26.67MB (it has been increased by 177KB) and supports Android 2.1 or above. You will notice the addition of a new file which is called “settings_description.xml” (it could be a new option that will be launched in the future), along with the deletion of 3 thumbnail files.Furthermore, if you decide to install this last 2.12.419 Beta on your Android device, you’ll also see that 197 files have been modified. For the moment, these seems to be the most noticeable things about this new Beta version of WhatsApp for Android.

So now let’s see how to install it on your device. First of all remember that you can’t download new Beta versions from the official Google Play Store, but you can do it from whatsapp.com/android. Once you’ve downloaded the 2.12.419 Beta version of WhatsApp for Android you’ll have to enable the “Unknown Sources” option. This is the option that enables you to install APK files that you have downloaded from a third party source.

To enable the “Unknown Sources” option you simply have to go to Settings > Security (or Settings > Application, depending on the OS version that you have on your device). Once you’ve enabled this option, go back to where you’ve saved the 2.12.419 APK file and tap on it to start the installation of this latest Beta version of WhatsApp on your device.
