I have no idea what people are cribbing about, those giving less than 5 stars. This app is amazing. You can WHITELIST the few contacts whom you want to allow to call you, and BLACKLIST all the rest. And the beauty is, it gives an ENGAGED message, same one used by the telco. And it's FREE. Jeez man, what more do you want?
Warning: suspicious developers. Also, this app will not run if you have an adblocker installed. Trash app. This is a response to the broken-english crybaby response I got from the devs: I am the end user. I don't want to see your ads. I don't care about the money you lose by your inability to force ads onto my screen. I use Android so I can root and ROM and control MY phone. I gambled on a call blocker app, it sucked royally, and I uninstalled it and chose to warn others about its dreadfulness. I found one that works great with devs who can speak English, even running an ad blocker. Don't download this app, the foreign "devs" only care about money.
This app is good and very simple to use. It's exactly what I had ever needed... Really great
Rubbish user interface gave up and uninstalled
Seriously Wow I'm not going to uninstall adblock plus you're crazy bye bye app
Doesn't work on s7 edge
Many internal bugs have been fixed to make the app more stable.
