How did you solve the Android excess-notification problem?
Happy New Year! Let's all be helpful together, as a well-honed team.
Working together, we can solve even the toughest Android issues.
Like excess notifications.
Dunno about you, but I get so many notifications that I'm at risk of
ignoring them - which defeats the purpose of notifications after all.
Sometimes I get asked if a newly installed app should get notifications,
where I tell it NO if it's something like a weather app or browser.
But in other cases, like maps or SMS or calendars, you kind of want to get
"some" notifications (but not silly notifications like "you haven't used
this app in a while" notifications - which - I do get at times).
Sure, I added a one-tap shortcut to the notification log activity and
another to the notification history activity (why they're extremely
different reports on my Android 13 Galaxy is beyond my comprehension).
But even with shortcuts, I still have to wade through a gazillion
notifications to see which are important - most of which - are not.
Back to the question at hand to resolve in 2025... It's my premise that too much of crying wolf doesn't really help.
So I'd like to cut down on notifications to the absolute essentials.
But how?
How do YOU cut down on the notifications to the bare essentials?
What *kinds* of notifications are there, anyway, that we need to solve?
 #1. Status Bar Notifications:
 #2. Notification Drawer Notifications:
 #3. Heads-Up Notifications:
 #4. Lock Screen Notifications:
 #5. App Icon Badges:
 #6. Notification Channels:
 #   ? --
Note I just installed this app, which at least tells me, in words, what  #1
status-bar notifications are - but that only covers the status bar.
 Status bar (only) Voice notifications: (enable in Android 13 settings)
