Smartphones Play Key Role in Most Police Investigations

The reliance on smartphones in police investigations has soared, according to a recent report by Cellebrite. This Israeli forensics company conducted the 2026 Industry Trends Report, which surveyed approximately 1,200 law enforcement practitioners across 63 countries.

Smartphones Play Key Role in Police Investigations

The report revealed that an overwhelming 95% of respondents believe digital evidence is crucial for solving cases. This number is up from 74% recorded two years earlier. Furthermore, 97% of law enforcement officials noted that public expectation is for digital evidence to be utilized in almost every case. Smartphones, in particular, have emerged as the primary source of digital evidence, cited by 97% of respondents, a significant increase from 73% in 2024.

Enhancing Case Solvability with Digital Evidence

• 95% agree that digital evidence “significantly increases” case solvability.
• 62% of public safety agencies are reallocating resources to digital investigations.
• 42% are more open to utilizing cloud technology for evidence than 35% in 2024.

Challenges in Handling Digital Evidence

Despite the recognition of digital evidence’s importance, many respondents (94%) expressed concerns over its increasing complexity. This complexity contributes to an already heavy workload for law enforcement teams. Officers frequently handle 2-5 devices per case and must also consider other sources of evidence, such as video surveillance recordings.

Several key challenges were identified, including:

• Locked devices present in over half (56%) of cases.
• iOS devices are deemed 86% harder to access than Android devices at 65%.
• The time-consuming nature of reviewing digital evidence, noted by 68% of respondents.
• Training deficiencies and the difficulty of explaining technical details to non-technical stakeholders.

The Role of AI in Evidence Analysis

While over 70% of survey participants believe artificial intelligence (AI) could enhance the review process by identifying connections and translating content, one-third cited agency policies that prohibit using such technology. Currently, only 28% reported using specialized analytical tools to aid investigations.

Public Trust and Technology in Policing

Public trust remains a significant concern, particularly following historic data breaches involving law enforcement. For example, the Police Service of Northern Ireland leaked sensitive information in 2024, and the previous year, Norfolk and Suffolk police inadvertently exposed personal data of over 1,000 individuals. Additionally, the Information Commissioner’s Office reprimanded South Yorkshire Police after they deleted 96,000 pieces of evidence from bodycams.

As police explore integrating new technologies, transparency and public consent will be essential. Matt Scott, the police and crime commissioner in the UK, emphasized the importance of maintaining public trust amidst technological advancements. Effective communication and established safeguards will be crucial in ensuring that new technologies are appropriately utilized in the realm of public safety.
