I updated my Galaxy S4 yesterday and today I can't locate the Blocking mode. Please tell me Samsung did not do away with this feature.
I would assume it was changed to Interruptions like on the S5. If so, it doesn't work exactly the same way as Blocking mode, but is close, and can be found via Settings > Sound and Notification > Interruptions
Thanks for this information, tikibar1. I have now changed my "interruptions" but I certainly liked the blocking mode better. I can no longer set the phone to accept a call from a particular number during the time "Do Not Disturb" is enabled and now whenever I use the phone there is a notification that Do Not Disturb is on, which is frustrating. Why do updates always have to mess up features that were working well?
