The effectiveness of this feature is backed by data from spam-blocking services such as Hiya. According to their 2025 statistics, about 31% of calls from unsaved numbers were classified as spam, and 4% were identified as scams. These scams often impersonate government agencies, tax departments, well-known tech companies, or online shopping platforms. In some cases, scammers even use AI-powered robocalls that mimic real human conversations, making it harder to identify fraud with the naked ear. This makes technological defenses like call screening more critical than ever.
