Have you tried restarting the iPhone?
Either hold the sleep/wake button until slide to power off comes up. Also you could do a hard reset hold sleep/wake button and the home button until the Apple logo appears.
Do you have the light notifications on?
The light on the top back side of the phone (that is used for flash when taking pictures), right?
Classic case of dropping your phone one too many times.
If you hit it just right the light will go off or flicker. That's not a solution only a confirmation.
Unfortunately the light can't be replaced without changing the main board
ugh really?a friend gave it to me. nah it doesn't go off ever lol...
i know i prolly should do this but i also need help and posted a message elsewhere if you are any good with calendar sync issues.. LOL
my iCloud and iPhone calls seem to sync ok but not the app on my MBP
This is 95% caused by liquid damage. The other 5% would be dropping it too much. A camera replacement will not fix the light. The entire phone needs to be replaced. If you have applecare it can be swapped at the Apple Store for $49 or $79 depending on when you bought applecare. If no applecare then it's $149 for iPhone 4, $199 for iPhone 4s, and $269 for iPhone 5, 5C, and 5s. If by some chance it's not liquid damage, and you are still under warranty or have extended applecare, it will be a free replacement.
ugh nah like i said i think a friend gave it to me.. so no warranty no apple care..as long as it works until iPhone 6 comes out LOL
now if only my calendar issue could be solved so easily
How is the battery life with the light on all the time.
If it does not turn off even when the phone is turned off or on, I am also betting that it has been damaged by liquid.
Try a DFU restore, this often solves software problems (won't do squat for hardware issues) but worth a try.
The flash is connected to the camera module. It's a LED, so it's not like you can just unscrew a bulb.
