Step by step

1. 

   Open Blocked numbers

   In the Phone app, tap the three dots at the top right, then Settings. Tap Blocked numbers.

   Done

2. 

   Add a number

   Tap Add a number. Turn on Unknown to block calls from unidentified callers; it was off on ours.

   Done

3. 

   Open Caller ID and spam

   Back in Settings, tap Caller ID and spam, under Call Assist.

   Done

4. 

   Check Filter spam calls

   Filter spam calls prevents suspected spam calls from disturbing you. On ours it was off and See caller and spam ID was on. Both switches looked greyed out; we did not try to change them.

   Done

5. 

   Look for Call Screen

   Searching Settings for Call Screen found only Google Assistant entries on ours, and the Phone app had no Call Screen row.

   Done

6. 

   Check message Scam Detection

   Go to Settings, Security and privacy, More security and privacy, Scam Detection. Ours had only Message scams, which was on.

   Done

If you do not see this option

• No Call Screen? Our Pixel 10a in Germany had none (step 5). It depends on the country.
• No call Scam Detection? Ours had Message scams only. Google says call Scam Detection is available in some countries, on Pixel 9 and later, with a SIM from that country. Source: Use Scam Detection

If this does not work

• Blocked the wrong number? Open Blocked numbers and clear the number to unblock it. Source: Block or unblock a phone number
• Spam switches greyed out? They were greyed out on ours and we could not test a fix. Google's caller ID and spam page explains how the features work. Source: Use caller ID and spam protection

About this guide

Blocking and spam filtering are in the Phone app's settings. Some Pixel call features depend on the country; we show what our German Pixel 10a had.

The screenshots are from our Google Pixel 10a with Android 17, in Dark mode, with a SIM inserted. We only looked at these screens and changed nothing.
