1. If you thinking about a great call blocker defanitly download this app.here.Very easy to use.. But phone rings when someone u blocked calls.. Blocker must not get ring if blocked person calls .. Blocked person must get information on calling that no.

2. Otherwise, it's a good app.Wonderful finally an app that does exactly what I wanted it to do I've been looking all over for something like this for years and this one finally worked thank you! only one issue on my text messages if a picture is sent I cannot view itBlocks the calls that are on the list.

3. That is what I want since the cell phone is my office phone and don't like getting a bunch of unwanted sales calls or other useless calls.

4. Does what is wanted.Does not block SMS, only phone calls.

5. But I know it's not sqlite as it doesn't even recognize it as a database at all.Every since i downloaded this App.the Robo Calls have stopped.

6. Very disappointing.literally searched for a long time to have such an app! best & easy one for not to get notified about specifically irritating calls and messages.

7. Only problem I have is that "Unknown" calls still come thru, rings quietly once and usually hangs up.

8. It also doesn't show any blocked calls.

9. The features listing states you can block unknown callers - so what am I doing wrong??? That is what I need, block unknown numbers with no ringtone, no voice mail, NOTHING.

10. Other call.bloclers requires fees & subscriptions & dont do have of what this does.

11. Google should start taking down this apps that don't workIt would be nice if, instead of backing up the blocklist to A database format, if you'd identify WHICH database format (sqlllite, for example).
