Hi, I'm using 4.1.1 and have a question regarding the Quick Start option in Settings. It says it will decrease boot time, but how exactly will it achieve this? First thing that comes to my mind is the sleep/hibernation option in laptops, which is actually using battery juice in that state. I hope this isn't similar to that. And another question is, is there an option to disable the start up and shut down sounds (my older Android I think 4.0 had this option)? Many thanks!
