With its minimalistic UI, mini call view pop-up, Duo integration, spam protection service, and unique call screen feature (available only on select number of devices and countries), the Phone app from Google is the go-to dialer for Android. It supports a wide variety of Android devices like all Pixel's and Android One - based phones.

GOOGLE DUO VIDEO CALLS

SPAM PROTECTION AND CALLER ID
See warnings about potential spam callers and report suspicious calls to help protect the community from telemarketers, fraudsters, and spammers. Block numbers to prevent them calling you again.
