I have had my Note 4 for just a week now (upgraded from the Note 3) and I have noticed that the blocking mode does not seem to work like it did on the Note 3. For instance, the "Turn off LED indicator" is not included (it was on the Note 3) and therefore the charging light stays on at night and it seems that the "Turn off notifications" option does not turn off all notifications (I was woke up in the middle of the night by either an email or text message). There is a paragraph at the top of the Blocking Mode settings screen that says "When this mode is turn on, notifications for selected features will be turned off.", but I have not found a way to "select" the features. Does anyone have a solution for any of this?
