Whatsapp has added a few days ago in update (2.11.186) thereof, the ability to hide the last hour connection in Whatsapp. In this tutorial we will show you how:
1 First accede to Whatsapp and deploy the menu. Pincharemos then "Settings".
2-Within "Settings" we will go to "Account Info".
3 Now we will give a "Privacy".
4 Then go to "Last".
5 Finally, we will give a "No".
This will create that nobody can see the last time that we connect to Whatsapp. How can you see, we can also choose to only your contacts can see when the last connection, or all users of Whatsapp (or not have them in our address book) can see that connection time.
I hope you have been helpful and if you have any problem with what has been said in the tutorial, do not hesitate to indicate it in this thread.
