5.0 out of 5 stars The only one that I found succeeds in China 9 Nov 2013
Verified Purchase
I have tried a number of SMS and MMS blockers for use in China. None of them in my experience block the frequent and extremely disruptive MMS messages I get a number of times each day and from which there is apparently no consumer protection to avoid. The only exception is this app! It works brilliantly well and effective in all aspects of monitoring and blocking unwanted intrusions by means of my mobile phone. I definitely consider it well-worth the payment, and I hope to continue to use this app for the conceivable future! One of the only improvements I can think of is that some attention might be given to improve the way times are written: 00.12pm is not the standard way 12 minutes after midday would be written in the UK, it would be better for me as 12.12pm or just 1212hrs to use a 24 hour clock. May be this could be an extra improvement on an already excellent product.

I have been getting about 5 - 10 calls a day even when registered with the TPS .

I set Extreme Call Blocker to hang up on the callers automatically followed with a text stating I was registered with the TPS and there numbers (from uk) were now logged and reported to the TPS .

The numbers that phoned started with the 3 same area codes all though the rest of the numbers differ I was able to set Extreme Call Blocker to filter these and log the calls the last one that called I sent a text bomb of 100 text direct to the number again stating I was signed up with the TPS !

Worked a treat and gave me a giggle .... I also have the app set to filter text message's.

I USE A OLD HTC WILDFIRE S .... the setup guide is quite simple click on the listed phone brands and follow the info on screen :)

3.0 out of 5 stars Does not block calls, frequently has to "force stop" 18 Dec 2012
By B. Hoffman - Published on
Verified Purchase
I've adjusted my review to reflect some changes. I did eventually get the call blocker to block calls, but the program crashes continued to occur. After contacting the developer, I was informed that this version of Extreme Call Blocker does not work with Ice Cream Sandwich. The developer sent me a link to download the correct app file and the correct version works flawlessly so far. Unfortunately, the developer also informed me that this version is not available on the Amazon App Store, but if you were to purchase from the Google Play store, you would automatically download the correct version. The version available on Amazon is simply the most popular version of the software. It would be nice if this was mentioned in the product description somewhere. As it were, Amazon customer service and the developer were both very helpful in getting the problem resolved.

Original Review
I purchased this app for use on a Samsung Galaxy S2 (Virgin Mobile) running Android 4.0 Ice Cream Sandwich. It looks like it has a lot of cool features, but the app doesn't work for me. It simply does not block calls. Numbers in my blacklist still ring the phone like any other phone call. I had to find a "silent" ringtone so that I no longer get bothered by calls I do not wish to answer. This would be a decent enough solution for me, but the calls still show up on the call log as a missed call. This is seems fairly minor, but for an app that costs as much as this one, it shouldn't happen. The app also hangs a lot and causes a "force stop" when trying adjust some of the settings, like setting up a calendar schedule to block calls on.

I have someone's old # that didn't pay their bills so this app transparently blocks those calls and I don't have to get a new #. I love the app and it does exactly what it describes.
