The Camera Flash is a mechanic in Five Nights at Candy's 2.

As the protagonist spends their nights in the Central Hall, animatronics will enter. These can't be spotted by normal means, as the Central Hall is mostly dark.

The player can use the protagonist's smart phone to light up the area for a short time by using the camera flash.

It also allows the player to see how close the animatronics are. If they are far away, then the player doesn't have to be worried, but if they are already over the desk, the animatronics will be close to jumpscaring the player and need to be lured away.

This can be done by using another mechanic, which is accessed via the locaion's camera system, which in turn is accessed by rising up the smart phone, so that it fills the entire screen.
