Sorry for creating such a generic thread but the lack of call/SMS blocking in Android options is surprising me. Such a gigantic user base without a simple and working solution, it seems like.
There are some apps which claim to do that but most of them are not working great. Only GoSMSPRO offers a "real" blocking&hiding feature but it's only valid for SMS' and it does its work by replacing the default SMS app.
Isn't there any blocking option on system level? Just type the numbers and it will block/ignore everything coming from those numbers. I do have a rooted lollipop ROM and only proper app seems like to be "Root Call Blocker" which asks permissions for so many things like Internet Access etc.
Thanks in advance for any comment!
