App Icon Badges Not Showing. But you don't have to use that one. This site contains user submitted content, comments and opinions and is for informational purposes only.
Open the settings app and go to apps & notifications. You can show badges (dots) on app icons when apps receive notifications. You can see these numbers on the home screen or app drawer.
Go back to your home screen when you're done and you'll now notice a cleaner display absent of tiny icon badges.
By default enable badges on samsung galaxy s10 plus and s10. I reinstalled the outlook app, confirmed i have notifications within the app set on, and confirmed that settings in both android and launcher have notification badges turned on. Tweak the settings to switch on the feature and check if it works as intended to solve notification badges not showing on galaxy s9. Anyway for a samsung phone go into your phone settings (not launcher) and search for app permissions.
