I don't know how it's causing a problem since it shouldn't get in the way when you're holding the phone, and I don't know why the light is such a problem to some people. It's not even all that bright. LoL!! The LED light to show that you're phone is charging is like just as bright. LoL!!
Anyways.......... Oh my google!! I was talking all that trash and I can't even find the option. I know I seen it somewhere. Ima keep looking, but the notification light shouldn't be that much of a problem. I mean, if you have your phone locked, and you get a message, just like check the message. It's really there for people who leave their phone on silent. That way, when it starts blinking, that means you got a notification. And silent is not vibrate. You may like leaving your phone on your desk, but don't want the ringing to disturb other people in their cubicles and the vibrating neither, so that's where the notifying light comes in.
But really? I really want to know how is that light bothering people? I mean, if you get a notification, the phone vibrates, ring, and then this blinking light. The light isn't all that bright neither. And when you get this notification, you usually unlock your phone, which turns off the light. So why is the light a problem? It's not killing your battery at all. It's an LED light. If LED lights killed your battery, then why when your phone has about 10% energy left, a little red LED light turns on until your phone dies or gets put on the charger? An alarm clock illuminates more than that light. LoL!! I'm sorry for sounding so shrewd, but I really want an answer to that question. I'll find your answer, because I know I seen it somewhere. LoL!!
