A mobile phone can be submitted for expertise at the Forensic expert kollegium by both the seller or repair organization and the consumer. In case of a conflict situation when the repair organization returns the mobile phone to the consumer to submit the object of study for expertise, it is necessary to seal the mobile phone in the presence of both parties in order to avoid possible changes in the state of the mobile phone by the party delivering it to the forensic institution.
When submitting mobile phones for expertise of the quality, it is necessary to present a charger, battery, warranty card and a complete set of operational documentation (passport, manual or instruction) supplied with the mobile phone.
A mobile phone is allowed to be presented for expertise of the quality without the packaging from the manufacturer.
A mobile phone is presented for expertise without a SIM card of a mobile operator.
