Hey, I am new to Android and have been setting it up carefully. I realized that I am in dire need of a good call blocker because now my minutes are finite. I tried the Call Block app and found it not responsive. I had to enter the number more than once for it to register and for some reason, I also felt that system was slowing down just a tad. I'm not sure. I am writing to ask if anyone else has had similar experience with Call Block and if there is a better app. Yes, I tried Google Voice. No, i don't want to change my number. No, just subscribing to their voicemail service does not give you the privilege to block calls/sms.
