What's a good Android app for identifying unknown callers and blocking spam?

Getcontact is an Android app designed to help you identify unknown callers and protect yourself from spam and unwanted calls. It works by leveraging a vast database of user-contributed information to identify numbers that aren't in your contacts. When you receive a call from an unknown number, Getcontact can often display the caller's name or identify it as a potential spammer, allowing you to decide whether or not to answer. A key feature is its spam blocking capability, which automatically blocks calls from numbers identified as spam by the community, providing a safer and more peaceful calling experience. You can also manually report numbers as spam, contributing to the app's growing database and helping other users. Getcontact also offers a feature to identify numbers via a search function, so you can proactively check a number's reputation before calling it back. This makes it a valuable tool for anyone looking to enhance their call security and avoid annoying or potentially harmful calls.
