What About Truecaller?

Truecaller is a free app that blocks robocalls and spam calls, offering features like caller ID and spam detection. However, it also has drawbacks:

Potential for Blocking Legitimate Calls: Some users have reported that Truecaller may block legitimate calls, including important ones from contacts. (vox-guard.com)
