It is not suppose to. It is used to complement existing notification.
Then quite frankly, it doesn't do a very good job. And this is an interesting position change, considering the chief complaint - that urgent notifcations are lumped in with non-urgent ones - was batted down by the pro-LED lynch mob with "oh, but you can make it change colors!"
So now this ISN'T the answer to that problem?
Why are you over-complicating the LED lights by lumping in usage scenarios which the LED notification is not designed for?
Oh, I'm sorry. I thought the LED was supposed to provide useful notification information. I guess this isn't the case? Because these "overcomplicated" scenarios are exactly how I expect to use my phone, and are well-served by iOS' existing notification schemes.
The main point is the LED gives you a continous and persistence notifications which the other kind cannot.
And I'm saying the persistent notification is worse than useless if it can't effectively inform me only of the notifications that I might want to be persistently notified of, as opposed to the rest. If it can't do this, then it's just meaningless noise the majority of the time.
Much like a blinking LED, merely saying "ditto" without providing any context is fairly meaningless noise. Just saying. Might as well not say anything at all.
Once again the LED makes this step more efficient
How? all it does its blink and say "pick me up! Something's happened! I don't know if it's important or not, but pick me up anyway and find out!"
So what's the point? Given the amount of information coming through my phone and tablet, "something happened" is a foregone conclusion, every time I want to pick up my phone. Might as well put an LED that blinks for the sake of blinking. It would be equally useful to me.
- that is you dont go and on the screen when it is not necessary.
Only that's simply false. At the risk of repeating myself: there are times when an event occurs that is not immediately important to me and won't require that I unlock my phone and take action. An on-screen digest tells me this. An LED does not.
Not sure why it is so difficult to understand.
I understand it. Maybe your LED light didn't remind you that I already sated I have used many smartphones with blinking LED notifiers, and found no positive value in it. It's of no use to me. If it is to you, great and I again hope Apple sees fit to throw you and your crowd a bone. Why you need me to proselytize to me and others about how great a meaningless blinking light is, is beyond me though.
Don't use it if you like to turn on your screen unnecessarily.
I won't, because I see no point in having a light there to blink meaninglessly and unnecessarily, providing no useful information.
Hmmm...I got the impression you think that LED notification is the MOTHER of all notifications that can replace all other types of notification.
Actually, it's quite the opposite: I KNOW the LED is NOT the mother of ANY notifications, and doesn't do its alleged job well at all. I've said this many times in many ways, but apparently you seem unable to parse this piece of information. How very telling.
OK. Fine. Maybe "superior" is a wrong choice of word. Let me modify that to "More".
I wouldn't even go that far, but if you feel that your blinky-light Android is the king of accessibility, I won't disabuse you of perceived exceptionalism, if it's really that important to you.
