What's the best Android app for identifying unknown callers and avoiding spam?

Contacts is a comprehensive tool for managing calls and identifying unknown numbers. Its core function centers on a live caller ID system that displays names and locations for incoming calls, even if the number isn't saved in the device's address book. This is particularly useful for screening calls from potential clients, unknown businesses, or delivery services. For spam protection, the app maintains a frequently updated database of known spam and telemarketing numbers, which is supplemented by user reports. When a suspected spam call is received, the interface clearly labels it, giving users the option to block the number and report it to help the wider community.

Specific features enhance its practicality. The automatic call blocker can be configured to silence or disconnect calls from numbers on a blacklist or from hidden/private numbers. Users can also search any phone number directly within the app to check its reputation before calling back. While generally effective, some reviews indicate the spam database can be less comprehensive in certain regions outside major markets. The free version is functional but includes advertisements, with a premium tier available to remove ads and unlock features like a more extensive call history log. For everyday users inundated with unwanted calls, Contacts provides a straightforward layer of defense and identification.
