Mobile forensics is mainly used in law enforcement but also used in military intelligence, civil and criminal defense, private investigations, corporate investigations, and also useful in electronic discovery. When conducting the mobile forensics there are different areas that are looked at, these include the internal memory which is mainly the flash memory.

The examiner will also look at the service provider logs which involve looking at the call details and also the text messages; these are retrieved through wireless carriers. They will also look at the external memory which is basically getting information from SD and SIM and memory sticks.
