How to make a Samsung Galaxy smartphone mute itself using Blocking Mode
So here's how you configure Blocking Mode on your Samsung Galaxy smartphone. First you must go to your Settings menu and find the feature – it should be listed under the "Personalization" tab. The mode is disabled by default so go ahead and enable it from the switch in the upper right-hand corner. An icon indicating that the mode is active should now be present in your status bar.
Okay, now would be a good time to decide whether you want Blocking Mode to be enabled automatically – during sleepytime hours, for example – or you'd rather toggle it on/off yourself. If you'd rather go with the timed option, disable the "Always" tick and choose a time range. Unfortunately, you may allocate only a single time slot during which the mode is enabled. If you prefer enabling the mode manually, leave the "Always" tick on. You may enable or disable Blocking Mode from the toggle in your notifications panel at any time.
We would strongly recommend that you whitelist your alarm clock – you do that by disabling the "Turn off alarm and timer" tick. You do want your alarm to wake you up for work, don't you? It is also advisable to allow some of your contacts to bypass the Blocking Mode – let's say your parents or your significant other. Emergencies do occur, you know. And that's it! Now enjoy your nights undisturbed!
