OK, I have tryed to find answer in the net, no, no hope. So, what the hell does this button/selection/whatever it is, actually do when its like this and when there is a line across it (disabled I presume)? This is accessible via volume buttons.
Dude, I would not be asking if it would tell me what it does.
So far I have been unable to figure out what it changes, or does it change anything. I thought it might something to disable notifications but no, thats not what it does. I have no idea what it does, does not seem to do anything, but ofcourse it does something. I just have no idea what and I have found out nothing about that button. Thats why Im asking.
