The built in flash fires brief burst of flashes and a noise is audible before shooting

Under low-light conditions, when you press the shutter button halfway, the built-in flash may fire a brief burst of flashes. It illuminates the subject to enable easier autofocusing. Additionally, a noise may be audible when the AF-assist beam fires. This is not a malfunction.
