Android: Block anonymous calls
Most Android smartphones don't have a built-in option to block anonymous calls. Therefore, there are numerous apps that have addressed this problem. This guide shows you how to block unwanted calls using the "Calls Blacklist" program.
Prevent unknown calls with Android app
- Download "Calls Blacklist" from the Play Store and install the app on your Android smartphone.
- Start the program.
- Click the gear icon in the top right corner and select the "Calls" option.
- Now check "Block private numbers".
- If someone calls you with a suppressed number, the app emits a short acoustic signal and shows you the blocked call in the notification line. See the app log for more details.
