How to turn on the light when taking pictures on Apple's mobile phone?

1. Take Apple's 6s mobile phone as an example, unlock the screen of the mobile phone, find the "camera" option on the desktop, and click Open to enter.

2. In the upper left corner of the camera shooting interface of Apple's mobile phone, you can see a lightning icon. When the lightning icon has diagonal lines, it means that the camera flash is off, and the flash is not on when taking pictures.

3. Click the lightning icon, the diagonal line on the icon disappears, and the options of "Auto", "On" and "Off" appear at the top of the screen. Click the "On" option to turn on the flash.

4. The lightning icon turns yellow, which means the camera is in flash mode.

5. If the automatic mode is turned on, the camera will automatically turn on the flash when the surrounding light is insufficient. If there is enough light, the flash won't appear.
