I have been trying for almost an hour, no it does not work. I sent an email to someone not on my list, he replied, showing that the email address I used was correct. If I hover over the reply address, nothing happens, nothing pops up. If I right click his name on the reply I get the standard list of options; back, refresh, save as (which saves the reply as a text), etc., through till "inspect". Nowhere is any way to save the contact information. Other answers to this question that I have searched almost all tell me to click the three dots in the right corner of the email and I would get the option to "add". If I click on the three dots at the right of the reply, I get the standard list of options; reply, forward, filter messages like this, print, etc., through till "mark as unread", "add" does not appear. If I go into the google app, contacts, I can import an entire file of contacts from some other program but there is no option to add a single contact from an email. The only way to add him is to manually re-enter the information in google contacts. Windows Outlook made all this so much easier.
