Integrate into addressbook

[Jörg Sommer]

Is it possible to integrate into the address book to click there on a phone number and open it in Whatsapp?

I would like to deny access to the address book for Whatsapp. Hence, I need another easy way to switch from the address book to Whatsapp.

Do you mean the ability in the Google Contacts app to display "Open in WhatsApp" in addition to the ones listed below?

Copy to clipboard
Edit number before call
Set calling SIM
Block number

I meant these entries here:

I think it would be useful to show the caller's profile (for example to avoid spam without having to block everyone who is not in the address book).
