Part 1. Why is My Flashlight Button Greyed Out iPhone?

When your iPhone flashlight is greyed out (disabled and can't be tapped), it usually means one of these things is happening:

  • Camera is in use: If an app (like Camera, Instagram, Snapchat) is using the camera, the flashlight can get disabled. Even having the Camera app open in the background can cause it.
  • iPhone is overheating: If your phone is too hot, iOS automatically disables the flashlight to prevent further heat build-up.
  • Low battery or power-saving mode: Sometimes if your battery is very low or you're in Low Power Mode, the flashlight might not work properly.
  • System glitch: A random iOS glitch can cause it too - restarting your iPhone usually fixes this.
  • Hardware issue: If your flash (the physical light) is broken, the phone might grey out the flashlight option.
