A few days ago we share with all of you which was to date the latest version of Hangouts with its new improvements like the SMS support and the new functions of Video call. This APK that we shared was giving some issues on some devices that were buggy with these new built-in features.
That is why Google has rushed to repair these bugs or failuresy has surprised us with a new update that at the moment has not yet reached Spain, but we can download the APK directly.
This new version of Hangouts would be the number 2.0.122 and it would already have implemented the corrections for the errors regarding the SMS and the new functions in video-calls. 
In the next few days we hope that the corresponding update for Spanish lands will arrive, although for all those who are more impatient here I leave you Hangout v2.0.122 format APK for direct download and installation.
The installation or update method is the same as always. First we download the application, we navigate to the download path with any file explorer for android and we click on it to call android package installer, then as in Windows you just have to click on siguiente.
Remember that you must have the permissions to install apps from unknown sources from the settings of the terminal in which you are going to install or update it. To install or update to this new version we won't need nor of permits Root or anything like that, just download, run and install. 
Note: The images in this post are archival and they do not correspond to the new version presented here. As soon as you have time for in-depth testing, we will do a complete review of its new features and added functionalities.
