The WhatsApp calls may have arrived already, and is that there’s a lot of tracks which is giving the company, as has been the increase of APK of the beta version to application for Android, the version 2.11.481, which indicates it could have been introduced this new functionality, although still not active, obviously. But, furthermore, the last sequence of translations from English to Spanish tells us that before the end of the year could be try them in the beta version, English sequences that we see in the Network usage Beta version.
As you can see in the screenshot below are asking for translations of sequences as: %1$.1fGB, %1$.1fKB, %1$.1fMB, %1$d call, Incoming WhatsApp calls:, Outgoing WhatsApp calls:, WhatsApp call bytes received: y WhatsApp call bytes sent: which indicates that WhatsApp calls are in their final stages of development.
WhatsApp calls earlier than expected.
These two new clues, significant increase in the size of the APK in the beta version, and sequences of translations related with WhatsApp calls make us think that the development is completed, now just need to be put into practice and start debugging proper operation. What we are sure is that voice calls will be sort VOIP with more quality among of all messaging applications that currently exist.
