Why not make white list filter ?
Hi,
it brings some difficulties from user point of view if both blacklist and whitelist are available. For example you would have to order the groups based on importance since you can add “all unknown numbers” etc to the list(s).

I like this program
https://play.google.com/store/apps/details?id=fahrbot.apps.rootcallblocker.beta
Is very useful
I can decide to use Black List OR White List
Only a working solution at a time !!!
See this program, i am sure you make on avast similar function.
Hi,
I wouldn’t be so sure about that 
Since we already considered that and decided that appreciable amount of the users would set up the blocker incorrectly, unfortunately.

I do not undestand where is a problem.
You make this metod in firewall function (allow selected, deny selected).
I ask to implement this function also in call/sms filter (like in firewall) so that i not use other program for this function.
Yes and many users are confused, because they are not able to understand, how it is working.
Ok
I buy this
https://play.google.com/store/apps/details?id=fahrbot.apps.rootcallblocker.beta
This is perfect for me.
