I got the the One Ui7 this afternoon and I was excited for it like everyone but some features are worst than before like battery got more thicker than last one and for notifications you have to scroll down left side screen and for setting right side which makes it really confusing. Maybe it will take time to get use to it.
I'm little bit dissapointed. I expected some more UI changes. Ok battery icon top right corner finally looks better then previous. Left side next to clock island is very useful. Clock looks nicer in the left, thank you for this. But rest is minor just replaced app icons.
You can change the panel settings back to the old style, where you swipe from top for notifications and swipe down again for the control panel. I find it easier and quicker.
