How do you turn off a flashlight on a phone that fell in a toilet?

To turn off the flashlight on a phone that fell in a toilet, first ensure the phone is powered off and dried thoroughly to prevent further damage. If the flashlight remains on, try using the volume buttons or the power button to access the lock screen and then swipe down from the top of the screen to access the quick settings menu. Locate the flashlight icon and tap it to turn it off. If the phone is unresponsive due to water damage, consider drying it out completely and seeking professional repair assistance.
