The preparation phase

Once the mobile phone model is identified, the preparation phase involves research regarding the particular mobile phone to be examined and the appropriate methods and tools to be used for acquisition and examination. This is generally done based on the device model, underlying operating system, its version, and so on. Also, choosing tools for examination of a mobile device will be determined by factors such as the goal of the examination, resources available, the type of cellular phone to be examined, and the presence of any external storage capabilities.
