Hibernation behaviour in which processes are suspended when the device is powered off or idle but at the same time, remaining active.Not only the types of data but also the way mobile devices are used constantly evolve.Storage capacity continues to grow thanks to demand for more powerful "mini computer" type devices.As a result, forensic examiners must use a different forensic process compared to computer forensics. To remain competitive, original equipment manufacturers frequently change mobile phone form factors, operating system file structures, data storage, services, peripherals, and even pin connectors and cables.Consequently, whilst it is possible to determine roughly the cell site zone from which a call was made or received, it is not yet possible to say with any degree of certainty, that a mobile phone call emanated from a specific location e.g. for example, cell site analysis following from the use of a mobile phone usage coverage, is not an exact science. Mobile device forensics can be particularly challenging on a number of levels: Įvidential and technical challenges exist. Law enforcement, criminals and mobile phone devices.Use of mobile phones in online transactions.Use of mobile phones to store and transmit personal and corporate information.There is growing need for mobile forensics due to several reasons and some of the prominent reasons are: Smartphones may additionally contain video, email, web browsing information, location information, and social networking messages and contacts. Mobile devices can be used to save several types of personal information such as contacts, photos, calendars and notes, SMS and MMS messages. A proliferation of phones (particularly smartphones) and other digital devices on the consumer market caused a demand for forensic examination of the devices, which could not be met by existing computer forensics techniques.

The Process of cloning the mobile phones/devices in crime was widely recognised for some years, but the forensic study of mobile devices is a relatively new field, dating from the late 1990s and early 2000s.

So, We see so many new models arriving every year which is the forward step to the further generations. Some of the mobile companies had tried to duplicate the model of the phones which is illegal. The phrase mobile device usually refers to mobile phones however, it can also relate to any digital device that has both internal memory and communication ability, including PDA devices, GPS devices and tablet computers. Mobile device forensics is a branch of digital forensics relating to recovery of digital evidence or data from a mobile device under forensically sound conditions.
