The only thing I'm not fond of is the permission settings for each app. Now you have to go to permissions, then they are categorized by allowed and denied. To change, then you have to click on a permission and then toggle it. The extra step is not necessary. The toggles should be right there on the first permission screen.
The gesture hints could be hidden in OneUI 1.5 so not a new thing. Not sure how that could have been missed. 😂
I haven't bothered checking for OneUI 2 yet either. Maybe later tonight when I have some down time. 😅
Side gestures are not new either (been using it since Note 8). Maybe they decided to implement One Hand Operation+ into the current settings. I found it more efficient and ergonomically friendly for my small hands. No need to reach the bottom of the screen anymore. And I can launch notifications and other things with the gestures. I just hope they didn't dumb it down like they did when they brought out Bixby Routines. At least be able to program the gestures to what I want like before and where on the screen to activate. If they messed that up I will be sorely disappointed.
