How to setup call only mode Miss this feature from my old 'Berry - easily set to Phone Call Only mode overnight so support calls from work ring through but text/email notifications are silent. Is there a way to have similar one touch on/off functionality?  Thanks
You can use blocking mode. A feature in the Samsung TouchWiz devices (I believe made available in 4.0). 

Settings -> Blocking Mode


Enable blocking mode
Uncheck "Disable incoming calls"
Set the time that blocking mode should be enabled
Sleep until the phone rings




If you still want to actually receive the notifications for email and text messages you can do the following:


Go to Settings -> Sound
Select Volume
Turn up Ringtone
Turn down all the others




While these are not "one touch", you can do the second one right from the home screen.


Just hit the volume button
hit the button to expand the volume controls
adjust the volume of all the settings
