If you want complete control of how your phone reacts to calls and text messages in nearly any situation, then a tool recently released to the Android Market called Call Master has your number. This is probably the most in-depth, advanced call and text firewall for Android, offering some insanely useful features. It's from the same developer as Root Call Blocker, and actually uses that as its base.

This app is for rooted users only.

With Call Master, you can block calls and texts from a specific number after a certain time, send certain number straight to voicemail or auto-hang up on them, keep calls or texts private, and much more. The best part is that this app is completely automated, so you can set a schedule and never have to think about it again.

Want to ignore calls from your job on weekends? Don't want texts after 10 or 11 at night? Need to keep certain calls out of the call log? These are just a few examples of what you can do with Call Master.

    I don't like applications with these permissions. Seems a bit shady to me, no matter how well written the description is.

    Allows the application to call phone numbers without your intervention. Malicious applications may cause unexpected calls on your phone bill. Note that this does not allow the application to call emergency numbers.
    send SMS messages

    Allows application to send SMS messages. Malicious applications may cost you money by sending messages without your confirmation.

    Allows application to process outgoing calls and change the number to be dialed. Malicious applications may monitor, redirect, or prevent outgoing calls.

      If you give it root access, then it can do anything it wants with or without permissions set, as any other root-required app can.

    Argh. Why's it gotta be for rooted people only? It looks amazing but I like having a stock system.

    • Steve

      The things it has to manipulate can't be done with the standard Android API... the program has to hook down into the system itself and it needs root to do that.

      So run a rooted stock ROM.

    I tried root call blocker and really like that it supposedly has the ability to block the call before the phone even rings but what I really love is that apps like Mr. Number block suspected spam calls from numbers that aren't in your block list. A combo of the two would rock. I tried running the two together but they cancel each other out and neither works.

    So this is the Android equivalent of iBlacklist and MCleaner on iOS?
