Stable started rolling out 4 days ago...
Did you send this feedback as part of the Beta Programme being a tester via the route intended for Beta testing as well as posting here ?
Current Phone ~
Samsung Note 20 Ultra 5G SM-N9860_256Gb SnapDragon 865+
Samsung One Ui 3.1/ Android 11.
You are forgetting the following:
9 removal of maximum power saving more
10 appearantly less flexible medium power saving (which is the only mode now)
11 no more the possibility to swipe on lock screen clock to go between various panels like music ect... now you need to click on the clock to open it fullscreen and then swipe
12 overall simplificaton which in many cases became a lost of control options
Hope they fix this in the 3.1 version
