Direct answer
A failure immediately after a known change should be checked for new defaults, stale pairing, power sequencing or compatibility before factory recovery. For Pixel Call Screen, first confirm Pixel Phone is default and test with a normal unknown caller outside Focus.
What this covers
- Pixel Call Screen with this exact failure state
- Diagnosis across feature eligibility versus Phone app version, default-dialer and network
- Customer-accessible observation, settings and external components
What it does not cover
- ×A displayed manufacturer error code with a different documented meaning
- ×Live electrical, sealed-system, internal battery-cell or gas repair
- ×A claim that every model exposes identical controls
Capture the exact failure state
ReversibleRecord the change, version, outage time or newly connected hardware and the last known working state. Expected behavior: answer eligible calls through the supported Phone app, language, region and account.
Isolate the component boundary
ReversibleConfirm Pixel Phone is default and test with a normal unknown caller outside Focus. Remove or roll back only the reversible change, or test the previous direct path. Boundary to separate: feature eligibility versus Phone app version, default-dialer and network.
Correct only the proven cause
ReversibleUpdate the Phone app and enable only supported Call Screen options. Reapply compatible settings, update both endpoints or replace the incompatible new path.
Verify and stop safely
ReversibleRestart twice and confirm the feature remains stable with the intended change present. Do not treat automated screening as an emergency-call or spam guarantee.

Common follow-ups
What should I check first when Pixel Call Screen has this problem?+
Confirm Pixel Phone is default and test with a normal unknown caller outside Focus.
Why not factory-reset immediately?+
The useful boundary is feature eligibility versus Phone app version, default-dialer and network. A reset can erase state without proving which side failed.
When should I stop troubleshooting?+
do not treat automated screening as an emergency-call or spam guarantee.
