I'm using note 20 ultra
Doesn't make sense to put media player above brightness bar. How often do people change brightness compared to control media. May as well have media control closer to your thumb. Seems like people are going to be touching the brightness bar by mistake a lot more with this position. Also some apps you close by swiping them away. That's no longer possible because swiping just goes to the next media app. Not very well thought through.
Lock screen media control you can't change the time stamp on the track like in 2.5. Another downgrade.
Secure folder has it's own notification sound which can't be changed.
Phone control lags a lot. Especially gestures.
