1) Notifications categorization
2) UI improvements while launching and closing apps or scrolling through content
3) Device care (Battery) improvements. Inside storage you can even select which apps to exclude.
4) Lock screen widgets
5) FPS foot print is bigger and may be improved slightly. Not noticeable though.
6) For me battery life increased with much better idle consumption (Pic attached)
7) Option to choose apps in video enhancer
Things that are not so okay:
1) Number of icons shown in folder by default
2) Secret folder organization of apps
It’s a good update and makes the phone much awesome
