M02s has got the last security update on November ultimately, afterwards all update is finished, the way of comes on notification is completely goes downgrade. Its like Android 9 and OneUI 2 . So pls let me know how settle this issue .
I guess samsung removed brief notifications from the device because of the lack of perfomance they occur?
Im not think so ..
Yeah... It'll be a good idea to ask directly from samsung... Just contact them.😊
