Set iPhone Camera LED to Flash on Incoming Calls and Alerts

Oct 21, 2011 - 59 Comments

The iPhone can flash LED when alerts come in for calls and messages

The iPhone camera LED flash can be used to alert you to incoming calls, messages, and other alerts to your device. With this feature enabled, anytime a call or messages comes in the devices LED will flash repeatedly, even when the iPhone is on silent mode.

This great feature offers an obvious visual cue with a bright flashing light for when any alert or notification comes in to the iPhone. LED alerts on iPhone are an excellent feature that is not well known, but we’ll show you how to enable this on your iPhone.

How to Enable LED Flash Alert for iPhone with iOS

Using LED flash for alerts is possible in all modern versions of iOS and iPhone devices, here is how you can set this feature for your iPhone:

  1. Tap on the “Settings” app and then on “General”
  2. Select “Accessibility” in settings
  3. Locate “Tap LED Flash for Alerts” and tap on that
  4. Now toggle the ON switch next to “LED Flash for Alerts”

Flash LED for alerts on iPhone

Once you get an incoming message, phone call, or alert, the LED flash on the iPhone camera will blink and flash, offering a visual indicator that a notification or alert is coming through to the device.

Undeniably useful for those with hearing difficulties, but flashing the LED alert when an iPhone gets a call or message is also genuinely useful for those of us who regularly keep their phones on mute, lower volume, or who just want the iPhone to be a bit more obvious when an alert comes through.

This setting is supported by all modern iPhone and most versions of iOS, though it has been around for quite some time and the setting may look a little different on newer versus older iPhone models.

Flash the iPhones camera LED light on incoming calls or messages

For some background, this idea actually started as an old jailbreaking tweak, but Apple adopted it as an accessibility feature for iOS 5 and it persists in all modern versions and added a secondary “flash on silent” option in later versions like iOS 10. The flash LED alerts ability is agreat feature for just about everyone with an iPhone, try it out if it sounds like something you may appreciate.

By the way, desktop users can enable a screen flash on the Mac for alerts which is sort of similar offering a visual clue for alerts and notifications.

  20. […] some ways this is similar to the iPhone’s LED light alert feature that flashes with incoming phone calls and texts, except that it flashes for all alerts on the Mac, […]

  21. Jiten says:

    thanks dude…really gr8 help

  22. Idiots says:

    Phone has to be locked or in sleep mode to work :) that’s exactly what it is brains over here

  23. Nidhi says:

    Incoming call flash light option is only available for 4s ?? Or we can set on iPhone 4 as well.

  24. Cherie says:

    I couldn’t get it to work on my phone. After reading the posts on here, I switched the camera flash to auto and it worked!

  25. Neiro says:

    Me too I can’t get it to work :( Mine is an iPhone 5 with iOS 6…

  26. topdog417 says:

    Mine works any which way with all apps or no apps running. locked screen and unlocked. silent mode or regular. Only thing I need to do was have my camera flash on auto.

  27. The trick is that you can’t have any background apps running (like the ones that sends notifications etc.) You will have to double click home button and then long press one of the app icon on the task bar and then cross all these background apps out! Then it will WORK. TESTED for BOTH ringer mode AND vibrate mode and ON ALL CALLS or Notifications! And you must lock the keyboard or iPhone is asleep. IT’s workable :D

  28. guest says:

    Go to General->Accesibility and turn of Flash Indication for incoming calls.

  29. sebastianf says:

    the flashlight in the camera app must not be turned off.
    it hast be set to auto or on

  30. chris says:

    here’s the lowdown:
    LED works with 4s
    phone MUST be locked
    Face up / Face down does not matter
    running background apps does not matter
    works for rings and texts (at least, thats all i care about)

    • Walter Gassner says:

      It only works for a short time…Is there anyway for it to KEEP flashing so I will know that a call came in when I was away? I use my iPhone as my home phone, and is always plugged into electric, so don’t worry about battery life.

  31. Rich says:

    Finally works thank so much

  32. Marky bassline says:

    Ur phones gotta b locked after uve done the settings then it will flash:)

  33. Hank says:

    Just noticed today that mine is working after applying recent update via iTunes. Tried calling my cell from a land line and it did NOT flash. Got a call from out of state and it did flash. The switch is on…the apps are all closed and phone on vibrate. STRANGE

  34. Swapnil says:

    My LED lifht is not turning off even if I have changed the accessibility settingd…pls HELP!!

  35. Daisy says:

    I have the 4S and the flash works fine, with or without apps running and it works with both silent and ring on/off for texts, calls, alerts, etc.

  36. DK says:

    Go to camera and set flash to auto or on. Then it works.
    Most probably you have turned it off.

  37. Jon says:

    Don’t work on 4s bit of a silly one really

  38. Debora says:

    Finally!!! thank you so much for helping me switch off this feature. It became so tiresome when my phone flashed at everything… calls, texts, alarm etc and I couldn’t remember how to switch it off.

  39. Dawn says:

    It flashes only once when the text, call comes in but not repeatidly.

  40. Demon says:

    What is it with Mono audio, i think the iphone 4 is Mono, the speaker is on the right on bottom

  41. Demon says:

    It works on my iPhone 4, on silent mode, and in ring mode, for incoming calls, sms, mail, and i have background apps running

  42. KSRae says:

    I go through these steps and there’s NO LED Flash Alert listed there. And yes, I’m on iOS5. Any idea where else it might be?

  43. Devy says:

    Tried many ways to get it work: restarting, switch the feature on/off, it DID finally WORKED. The trick is that you can’t have any background apps running (like the ones that sends notifications etc.) You will have to double click home button and then long press one of the app icon on the task bar and then cross all these background apps out! Then it will WORK. TESTED for BOTH ringer mode AND vibrate mode and ON ALL CALLS or Notifications! And you must lock the keyboard or iPhone is asleep.

  44. Jonathan says:

    Actually only works on TEXTS not calls…

  45. Devy says:

    Turned in on, called on both silent or ringer, it DIDN’T work for my iPhone 4S!

  46. clasqm says:

    what does this do to battery life?

  47. MotionMan says:

    You say “EVEN when the iPhone is on silent mode.” Actually, it works “ONLY when the iPhone is on silent mode.”
