Google has announced that there is an update rolling out now for its Phone app which will add some spam protection. With the update, the Google dialer will show a red splash screen on a call that is suspected to be spam. Additionally, you'll be able to go into your call history and flag specific calls as spam, if Google doesn't happen to catch it, and report those numbers to Google and block that number in the future. Google notes that you do need to have the Caller ID feature turned on in order to get the spam protection. You will also be able to turn off the spam protection if you'd like.
We'd expect that Google has a pretty solid database of spam calls as is, both from people searching for numbers that turned out to be spam but also because spam filtering has been a part of Google Voice for years. Google has likely been able to glean what numbers are spam based on Google Voice voicemail messages that its systems have tried to transcribe over the years.
Let us know if you're seeing the feature roll through your device! And, although Google says the app is for Nexus and Android One devices, there have been some to claim that the Google Phone app can be installed on non-Nexus devices, so you can always head to the Play Store to give it a try.
