For the past 10 years I’ve only allowed two types of “notifications”
Phone calls. Vibration allowed, never sound.
Text/whatsapp messages. They are allowed to simply appear on the lock screen. No vibrations, no sound.
That’s it, for everything else I have to manually open the app to check it.
It’s shocking to me to see how the vast majority of people live with a constant barrage of notifications of which a huge majority are spam and/or not important at all.
