What is a first step when collecting a cell phone as evidence?

• A. Immediately power it on to check messages
• B. Place phone on airplane mode or remove battery or network card
• C. Share phone with a witness
• D. Keep it powered to download data right away

Answer: (B)

When collecting a cell phone as evidence, the priority is preserving the device in its current state and preventing any data alteration or remote access. The best first step is to isolate the phone from networks and power sources so nothing can be wiped, synced, or remotely accessed. Placing it in airplane mode or removing the battery or network card achieves this, helping to protect volatile data and maintain a defensible chain of custody for later forensic imaging. Why the other actions aren’t appropriate first: powering the device on to check messages can trigger automatic data syncing, cloud activity, or even remote wiping, which would modify the evidence. Keeping the device powered to download data immediately can alter data or bypass proper forensic procedures. Sharing the device with a witness risks contamination or unauthorized access and undermines the integrity of the evidence.
