Slow response on a phone or tablet is almost always storage near capacity or a background sync, not processor failure. 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

0 of 4 completedCapture the exact failure state
ReversibleCheck available storage, and whether a backup, update or large download is running in the background. 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. Compare the delay in a nearly-empty app versus the affected one, with background app refresh paused. 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. Free storage, let the background task finish, or clear the one app's cache/data where the OS supports it.
Verify and stop safely
ReversibleRepeat the same timed action twice with no background task running. Do not treat automated screening as an emergency-call or spam guarantee.
