Hi, I'm having an issue with my new Samsung S21+. Ironically, I had same exact issue with previous phone which was an S10. This issue is that system notification remain on my screen for roughly 5 minutes. I can not swipe it or click it away. These notifications are like "alarm set for 10 minutes" "text converted to group message" "error: network error". How do I fix this? Im not hopefull seeing it did same thing on previous phone.
