The iPhone’s flash is a useful feature that can be used to brighten up photos and videos taken in low-light conditions. Turning on the flash is a simple process that can be done in a few steps.
To turn on the flash on your iPhone, open the Camera app and tap the lightning bolt icon in the top left corner of the screen. This will cycle through the three flash modes: Off, On, and Auto. Select the On option to turn on the flash.
