Like the title states I have my S4 through Verizon and there isn't a blocking mode in my settings. I have tried searching but have not been able to yield any results. I want to use this feature cause I get notifications in the middle of the night that go off and wake up my Wife. I would prefer to use this feature cause I will never remember to keep putting the phone on silent at night before bed. Can anyone point me in the direction of the answer? Thanks!
