Symptoms

  • Flash doesn't fire when taking a photo
  • Flash icon shows on but photo comes out dark anyway
  • Flashlight feature also affected, or only camera flash affected
  • Flash worked before and stopped suddenly

Likely causes

  • CommonLow battery restricting flash useSome phones disable flash below a certain battery percentage to save power.
  • CommonPhone overheated and temporarily disabled the flashLED flashes generate heat and can be disabled if the phone is already warm.
  • PossibleFlash LED or its connector hardware failurePhysical damage or wear can cause the flash to stop working entirely.

What to do

  1. Check the flash setting in the camera app and set it to 'on' instead of 'auto' or 'off' to test.
  2. Charge the phone above 20–30% and try again.
  3. Let the phone cool down if it feels warm, then retest.
  4. Test the flashlight/torch feature separately from the camera flash to see if only the camera-triggered flash is affected.
  5. Restart the phone.
  6. Check for a software update.

When to call a pro

See a repair shop if the flash still doesn't fire when charged, cool, and manually set to on, since the LED hardware may have failed.
