What should I do with a damaged mobile device?¶

A damaged mobile device may still hold valuable evidence, but further handling can make the damage worse.

Why this matters¶

The dangerous assumption is that a cracked, bent or non-responsive phone has no evidential value. Internal storage, SIMs, memory cards, cloud links and device identifiers may remain recoverable.

What to record and do¶

Record the device exactly as found. Photograph all sides, the screen, ports, case, cables, debris and the location where it was recovered.

Note whether it is powered, warm, vibrating, making sounds, showing lights or responding intermittently.

Do not repeatedly press buttons, flex the device, reconnect loose components or attempt improvised repairs.

If the screen is damaged but displaying content, photograph what is visible before the state changes.

Be alert to battery damage. Swelling, heat, smoke, odour or puncture creates a safety risk that takes priority over evidence preservation.

Do not charge a damaged device without appropriate advice.

Keep detached parts, SIMs, memory cards and fragments together with clear continuity.

Avoid cleaning dirt, blood, water or residue unless required for immediate safety and properly documented.

If the phone may contain volatile live evidence, seek specialist support urgently.

Package and transport it in a way that prevents movement, pressure, short circuits and accidental activation.

Record whether the device was connected to power or another system when found, and preserve any damaged cable or accessory that may explain the condition. Do not remove the battery unless a safety specialist directs it.

Operational takeaway¶

Preserve a damaged phone’s condition and components, prioritise battery and electrical safety, and avoid testing, charging or repair without specialist support.
