WARNING - 99% OF "IT STOPPED WORKING" ERRORS ARE CAUSED BY timed out root requests after auto-updates, to use this app together with auto-update in Play, you MUST disable re-authentication in your superuser app.

WARNING - app generally only supports devices commonly available in the West. We will ignore requests for compatibility with random knockoffs and no name provider phones.

WARNING - multi-sim devices are not officially supported, though after version newer Qualcomm and possibly other chipsets should work. This does not mean everything will work on every phone. It means it MAY work on your phone. As a general rule more expensive will be more compatible. Stay away from Chinese devices, especially OEMs, they are likely to have custom RILs that we will never support. If you need this app and dual sim, contact us before you buy your next phone.

This app does not control your voicemail service. If your blocked calls are being sent to voice mail, try another blocking method or use Google Voice. You can simulate a disconnected message by forwarding busy calls to a number that doesn't exist.

OUTGOING CALL permissions are needed for hidden mode, using the dialer to enter a password.

ACCOUNTS are needed for Google Contact Groups.

SEND SMS needed for auto replies and SMS routing.

INTERNET ACCESS is for licensing and the "Write to us" feedback tool.

LOG DATA is only sent with your permission via the "Write to us" menu item in Settings. You do not have to send anything if you don't want to.

    While the app functions perfectly, according to my battery manager it used 20% of a single charge on my galaxy s5. This is completely unacceptable, hence the 2 star rating.

    @farhbot, I want to get the $6 pro version of this app, but I have a few questions. I use t-mobile visual voicemail to check my voicemails would the pro app be able to prevent voicemails from going there, and also if I get a call while I'm using my phone, will I go to the incoming call screen before the app rejects the call, or does it all work in the background

    No calls or text get through. Can set options to completely run in the background which I really like. By far the best blocker I have used. Edit: The screen flicker is gone. I have zero things to complain about in this app now.
