Iphone 4 light stays on

This just happened to me when I was just carrying my phone around. The light was on for about 20 minutes or so and it blinked a few times and then shut off. Should I still take it to the store and try to get a new phone?

If it was just for 20min and its off now you cant prove it to apple, but if it happens again and the light is still on when arriving at apple store (as a proof) then yes, especialy if warranty is about to expire.

same issue here. hope Apple support have something to say.

yes go asap!

I won't purchase anymore I product in my life . I am fedup with this light on problem ! Two times they just updated the iOS to solve this matter but every times the problem come back! And they are suggesting me to not install any apps to stay out of this problem! Men I phone without a application !!! Hey apple wake up ! I want a solution .

To temporarily fix the problem (sound crazy) but in this case violence is the only answer up until you take a trip to the good people at Apple. By that i mean give it a good tap on your knee or gently squeeze under the volume button, it's not the best way but hey it does get annoying and can fry the battery and overheat things, what is wrong is a common defect in many iPhone 4s which is the backplate inside the phone is not seated correctly which allows it to some how turn on the flashlight.

Best bet is to take it into Apple or take off the back and re-seat the plate.

Hope this works as it did for mine, if the problem persists then they will gladly help you out or even giove you a replacement since it is a hardware fault and nothing you did to make it happen.

The service is alway phenominal, even when you have the smallest or biggest of problems they will always fix it with a great attitude and are happy to help.

Please do yourself a favor and don't beat the crap out of your iPhone 4 trying to get the LED light to turn off!! Yes this might work buy you'll probably end up breaking something else in the process... The reason it works is because apparently there is a problem with the camera module (hardware) that creates some sort of short in the wires that allows the light to stay on. The only real fix that apparent to me (after opening up my case) seems to be to replace the whole camera module... which is very easy to remove and according to a previous post I read only cost some guy $35 at an "Apple fix-it place." So if your electronic/tech handicap... take it to someone who isn't... If you have any simple tech experience... open up your case (2 screws on bottom), slide back off (downward direction) and then remove top metal cover plate (4 screws) to uncover the connector of the camera module. Once the connector is free one more screw holds the module and and poof its free... now get a new one and screw everything back in...where you might ask... IDK I'm figuring that one out myself and will get back to you...but hey at least the freaking light is OFF now!

found one on ebay for 5-10 bucks... or you can google it... I've seen one for 20 and one for only $3...

I gently tapped mine on the floor a few times and mine turned off if all else fails hit it with a hammer

Same thing happened to me, So i went to the apple store and they said theres a problem with the wiring inside the phone. They fixed it for me then but after a few months it turned on again.

This has (possibly temporarily) solved the problem for my 4s. I took about 10 forced flash pictures in a row.

Good Luck

I just did this for my wifes phone that she dropped in the hot tub. After removing it from a bag of rice the light was still on. Tried the hitting, pressing the sides, and then I finally did the 10 forced flash pictures and no more light. Thanks for the suggestions BillChas.

I have been reading this post as my husbands iPhone 4 developed this problem. There was moisture in the camera lens and the back camera light was continually on as described. I tried every single suggestion posted here. Nothing worked. It is way out of warrantee so I had nothing to lose. The camera part needed replacing. Removing the camera from the phone is extremely easy. Many how to's can be found on YouTube. Purchasing a replacement part is also cheap. I managed to get one for £2.95. So far I have only removed the faulty camera whilst I wait for the replacement. The phone is back together and works perfectly fine without the camera (except the camera function obviously). On inspection, there is erosion to the connection to the camera piece. This is what makes is short and therefore the light stays on. Dislodging the erosion in one way or another may explain the temporary fix of which people speak of when they have pushed on the back and banged the phone against a table. The camera piece needs to be replaced. I also suggestion submerging the phone in rice for 24 hours to remove any residual moisture. I also strongly suggest that when fixed, you invest in a headphone socket plug to prevent further moisture entering the phone. This must be a design flaw.

My iphone 4s has not given me problems for the year and a half that I've had it. This morning my LED light also came on (for about 5 hours) and wouldn't for anything go off.

I tried:

1. Shutting down and restarting

2. Downloaded flashlight apps (2)

3. Restored and backed up and restarted

Nothing.

Then, I took out my sim card and shut it down and restarted it. Now its off (has been for about half an hour).

Its clearly not a permanent fix and Apple already asked me to bring it in when I phone them earlier as they'll have to replace the camera. Until I go in and have it replaced, I'll keep removing the sim card if the LED light does come on again, as it gets so hot that I'm afraid the heat might permanently damage the phone...

I had this problem, turns out I accidently turned on the flashlight function. Swipe up from the start page and the flashlight symbol is there to turn on and off. Glad it wasn't malfunctioning as I just took the case off and promptly dropped it 2 days ago.
