2) When the screen is on and I receive some messages, the notifications remain up for too long: while I do other things, they cover the top of the screen (where there are often some important options of apps in use) and I have to wait the notifications disappear to use that part of the screen. Alternatively, I can slide to the side the notification when it appear to clear the screen without wait, but it won't be present in the notification panel (I don't know if this is the exact name). I use a bad example to be sure you have understand, because of my bad English: in the iPhone the same problem is resolved by scroll up the notification, but it remains in the notification panel. Maybe this is not an important problem, but when I receive a lot of messages in a few seconds, it's annoying
5) Once I put a screen lock, I can no longer control the music playback when the screen is locked. So I can't change the song for example. Why not implement the function even if the device is protected by a screen lock?
7) The max of automatic luminosity is less than the max of manual luminosity; if I am under the Sun with the automatic luminosity, I have to change the option to use the max of luminosity.
