[SOLVED] LED light always on, what could be the reason?

History

My LED light on my iPhone 4S stay always on. I try to re-initialyze the phone without success on LED light (the camera flash in fact).

I have all updates done, and it doesn't change anything, even when I turn off the phone.

Otherwise it works well. The phone isn't cracked or breached.

Any solution ?

Thanks for your time !

Update

Testing with parts of my wife's iPhone... and it's working....

No problems with connectors in both parts

So I have to change for new part....

Final Update

Replacing Rear camera quite easily... and it works well now.

Thank you all for your disponibility !

Edited by: xgonin ( )

I will check the camera to see if it works.... Maybe I have to change these ?

Interesting problem, I have had 1 phone in my shop with this exact problem and it turned out to be corrosion on the motherboard (water damage) , I would disassemble your phone and inspect all parts and treat any corroded spots with alcohol and a toothbrush, good luck. iPhone 4S Teardown

Thanks for your quick answer, but I'm sure that I never had water damage. I'll try to disassemble it and inspect it... Wait and See !

xgonin,

Thanks I would love to hear what you find out.

Mitch Rush,

Nothing special found after inspection of my iPhone... No corrosion, all connectors OK, the liquid indicator is white.... Maybe it is an hardware issue ?

xgonin,

Yes, I would try replacing the Camera-led next, they are cheap, if that doesn't work you should try restoring it, several times if necessary, I know that's a pain but I have had to do that several times to make a camera work correctly, something else, if you don't have a flashlight app I would get one and see if you can turn the led off with the app open, keep us posted, good luck !

Mitch Rush,

Hi ! It doesn't change anything with an App with flash, like iTorch. I can turn on and off the light with the App. When closing the App, the symptoms are the same....

xgonin,

the circuit switch for the led is probably stuck and what you should do is call tech support to try and help you with your problem.

oldturkey96, another poor answer. Please explain where the circuit switch is located;-)

Last time I had a wet phone with this issue I cleaned the connectors for the camera and it worked fine afterwards.

Yes but mine wasn't wet at all !

Hi,

Every computer machine has a bios setup the hardware how it will work,

So I suppose it is a virus in the mainboard reached by any way.

And the best solution is returning to main manufacture to solve it.
