You can turn off the flashlight on your iPhone using two different methods:

Method 1: Control Center

1. Swipe down from the upper-right corner of the screen on iPhone models with Face ID (iPhone X and newer) or swipe up from the bottom edge of the screen on iPhone models with a Home button (iPhone 8 and older) to open the Control Center.
2. Look for the flashlight icon, which looks like a flashlight beam, in the Control Center.
3. Tap the flashlight icon once to turn it off. The icon will no longer be highlighted, indicating that the flashlight is off.

Method 2: Siri

1. Activate Siri by saying “Hey Siri” (if enabled) or by pressing and holding the side button (iPhone X and newer) or the Home button (iPhone 8 and older).
2. Once Siri is active, simply say, “Turn off the flashlight.”
3. Siri will confirm and turn off the flashlight for you.

Using either of these methods, you can quickly turn off the flashlight on your iPhone.
