On my Pixel 6 Pro I get wayy too many spam calls.
For some reason, the normal Google Fi setting to block spam doesn’t work. I’ve used it in the past:

After getting irritated and giving up, a Redditor said use the “Call” app screening:

Works great, although, make sure to turn off this screening when you are at the hospital for a loved one and are awaiting a call from the hospital.
No need to have that friction when they are trying to call you to pick them up.
