How does the flash on a camera phone?

What is Flash? Flash does not come every time you use the camera? I hear automatically illuminates when the brightness is too dark … Is it true? When I use my dad's camera, the flash fires every time I take a picture and do not want the flash in the heel and is really brilliant!

flash is used when a camera is dark for a good image to be taken into account for the flash lights up that the area of the image. flash may come at any time, but you can put it on auto and then only when the camera should come on think you need to leave your camera to.to parents doing that you need to go into settings and turn and find flash and self-selection or better than the flash will still come in when the dark. I hope helped
