I followed what the guy said in the video. I didn't even have that option to "ON" for that setting for any of those notifications.
I think that the phone just turns the screen on when it gets fully charged. I know my wife's does, and she has a Note 10 (regular not Note 10 plus). I know my Note 10 did the same thing before I had my S22 Ultra (which is really a Note 22 Plus).
It was a good idea and video to watch, and appreciate the info. I actually never knew those settings were even there on my S22 U phone. I like everything on my phone to be silent. At most I will allow vibration for a call, text or notification, but usually I don't even want that. I have my Galaxy Watch 6 (and watch 4 before that, and watch 2 before that) on my wrist to be notfied if need be. I have that set to silent most of the time, but during the day it is usually set to vibrate.
As a business owner for now 30 years, any phone ringing or text pinging is a stressor I don't want or need. We are already inundated with bothersome sh!t as it is in our modern world, lol. I long ago got rid of audible ring tones or notifications. I will see a missed call or text or email and get back to it when I see it. The only time I make an exception is if there is an ongoing health or similar emergency with family. Recently my wifes father passed, and it was about 3 weeks of hospice/"time is close" with him being gone from this earth, so I kept my phone ringer ON during those weeks while he was still with us, because it was that important. Since then, everything to silent, or vibrate at the very most.
