Most of smartphone available today has equipped with lot of advanced features which will allow the user to do more activities with their phone. However, basic activities such as making calls remains one of the most frequently done by the users.

  2. Hello, I have a Samsung Galaxy s4, model SCH-1545 running Android version 4.4.2. I am wondering how I can stop blocked telephone numbers from leaving voicemails. Is this possible?

    1. Hi Paul,
      Thanks for coming and I'm sorry for the late answer.
      Samsung Galaxy S4 SCH-I545 is a Verizon version, isn't it?
      From what I know, you can turn off the voice mail feature in your Verizon phone by calling Verizon and ask them to turn this feature off. You may need to give them some information, e.g: your Verizon account or IMEI number.
      Once your voice mail is turned off, the incoming calls from the blocked number will be rejected automatically.

    1. Hi Paul,
      If you don't mind, you can try a third-party call blocker app named Extreme call blocker. This is a paid app. This app has a feature to prevent the caller from leaving you any voice mail.

    1. Hi SkyDave,
      Thanks for coming.
      From what I know, the auto reject feature in Samsung Galaxy phone doesn't have an option to block calls without logs. However, maybe there's a third-party app in the Play Store that has the ability to block calls without logs. FYI, I've tried find it, but found nothing.

      Yes, you still can call the number you have blocked since it only blocks incoming calls.

    1. Hi KeepNitRealGf™ Joyce Ella Paquin,
      Thanks for coming.
      Since the default auto reject call feature in Samsung Galaxy S4 can't block incoming calls from private numbers, you'll need to install a third-party call blocker app that has a feature to block private number. FYI, I personally use Blacklist app to block calls from private number in my Samsung Galaxy S4. You can get this app for free through the Play Store app.
