  1. If on, switch it off. If off, leave off.
    • Note only under exceptional circumstances should the handset be left switched on and in any case every precaution to prevent the handset connecting with the Communication Service Provider should be made. Consider use of a Faraday Bag (Shielded Bag). An example of a cellular seizure package is Paraben's Handheld First Responder Kit which also includes a Faraday Bag.
    • Instead of switching off, it may be better to just pop the battery. Phones run a different part of their program when they are turned off. You may wish to avoid having this part of the program run.
  2. Collect and preserve other surrounding and related devices. Be especially careful to collect the power charger. The phone's battery will only last a certain amount of time. When it dies, much of the data on the device may go too!
  3. Plug the phone in, preferably in the evidence room, as soon as possible.
  4. Retain search warrant (if necessary - LE).
  5. Return device to forensic lab if able.
  6. Use forensically sound tools for processing.
