When flash is enabled, sometimes one LED lights up and sometimes both LEDs light up

In order to improve the quality of your flash photography, the camera flash has two stages: a pre-blinking followed by the main blinking.

• When the pre-blinking activates, only the cold color temperature LED indicator lights up.
• When the main blinking activates, both the cold and warm color temperature LED indicators light up with their brightness determined by ambient light levels.
