Whats a good app that block calls for my LG2 phone ?

[Deleted User]

My friend has this option on his android phone where if does not recognize a number he just simply tap/hold his finger on the phone number and gets a option to block the number, so that number will ring again. The LG2 does not have these options natively. So I need a good app that will do it. thanks

Advanced Call Blocker is very good and unlike many call blockers does not require root. But it does not add blocked a number by 'tap/hold'. Offhand, IDK of a blocker app that does.
