I get notification dots but I've turned off sounds for twitter and Instagram because the phone is beeping all day same for email, but that's just a case of going into apps and disabling it..S21U oneui4.
Doesn't matter if on WiFi or Mobile, I stop receiving notifications for certain apps, even though not optimised or disabled. And it's more frequent with apps that run in background as don't need constant access to them from main ui
I get that but you shouldn't have to keep clearing cache to solve the problem,strange how it works fine on my note 20 and S21 ultra can't be a software issue or every Samsung phone would have same problem..
Try wiping the cache partition on the phone and that should resolve the issue. To do this, just search 'how to wipe cache partition S20 FE' and you should find what you are looking for 🙂. Hope this helps! 😎
@walkerx: It might be worth checking Settings > Battery and Device Care > Battery > Background Usage Limits, to see if the affected apps are listed in Sleeping Apps or Deep Sleeping Apps, as this can delay notifications.
