Stop spam calls on an Android phone
The Phone by Google app (on Pixel and many other Android phones) can warn you about spam and keep those calls from ringing.
The pictures are drawings of the screens, not screenshots. Your screen may look a little different.
Drawing Step 1: Open the Phone app settings
Open the Phone app. Tap More options (three dots), then Settings.
Drawing Step 2: Tap Caller ID and spam
In Settings, tap Caller ID and spam.
Drawing Step 3: Turn on spam filtering
Make sure See caller ID & spam is on, then turn on Filter spam calls. Filtered calls do not ring, but they stay in your call history and voicemail.
Drawing Step 4: Block a number that called you
In the Phone app tap Home, tap the call, then tap Block or Report spam.
Good to know: If your phone's call app looks different (for example on some Samsung phones), open its settings and look for "spam" or "block numbers". Phones with Call Screen have spam blocking inside Call Screen instead.
