Another option and one that I use at night so that I can only get calls is to go into Setting>Sounds and notifications>scroll down to notifications "Do not disturb" From here you can select all sorts of options to just turn it on or off or set it to turn on/off automatically on certain days/times.
I'll be ordering mine as soon as my $200 reward card from Samsung gets approved. Great deal if anyone else has bought a new samsung phone and installed samsung pay in the last month.
