Why does Android keep letting spam calls slip through?
Android's spam call detection tools are evolving, but they're still not good enough

With spam calls outnumbering actual calls, they have become one of the biggest nuisances for smartphone users. Phone anxiety has assumed a new form, where I dread yet another call from a scammer. To its credit, Android has been improving its defenses against pesky calls. The situation is better if you have a Google Pixel phone since you get features like Call Screen and Scam Detection. Despite these improvements, a few spam calls continue to slip through the cracks. Are Android's spam call detection tools finally good enough, or must we rely on third-party solutions?
