LG Smart TVs Logging Data Even When Offline or on Standby, Investigation Finds

The investigation, which involved testing retail LG OLEDs, uncovered that the TV sets scan Wi-Fi networks for nearby devices, record audio logs through their microphones, and use audio and video sampling to recognize what viewers are watching across different inputs. Packet captures showed the TVs scanning the local area network for nearby hardware such as phones, offering insights into the extent of data collection occurring without explicit user consent during periods when the TV is not actively in use.

Data collection persisted even when the TV was disconnected from the internet, according to the report. The findings raise questions about privacy practices in modern smart TVs, where continuous monitoring may occur beyond what users expect from a device in standby or offline states.

Why This Matters

Privacy impact: Users may be unaware that their LG TV is collecting data about their home network, audio environment, and viewing habits even when the TV appears to be off.
Regulatory implications: The investigation could prompt scrutiny from data protection authorities, particularly under laws like Europe's GDPR or California's CCPA.
Broader industry concern: This case highlights the potential for smart TVs to serve as persistent surveillance devices in homes, affecting trust in connected consumer electronics.

Background

Smart TVs have long collected viewing data for advertising and content recommendations, but this investigation suggests the scope is broader than previously understood—including scanning for nearby devices and recording audio. Standby modes are typically assumed to mean minimal power usage with no active data transmission. The findings challenge that assumption, aligning with past controversies over always-on microphones in devices like smart speakers.

Key Perspectives

LG Electronics: Not yet commented on the specific findings. The company may argue that data collection is necessary for features like automatic content recognition or network-based services, and that users can adjust privacy settings. Privacy advocates: Likely to condemn the practice as excessive surveillance without meaningful consent, calling for clearer disclosures and opt-out options that persist even when the TV is offline. Security researchers: Concerned that the scanning of Wi-Fi networks for devices could create security risks or enable fingerprinting of homes, and that the lack of transparency around data logging undermines user trust.

What to Watch

LG's official response: A statement from LG may clarify whether the behavior is by design, a bug, or subject to change via firmware updates.
Regulator interest: Data protection authorities in jurisdictions like the EU or California may open inquiries or require compliance reviews.
Consumer class actions: The findings could spark lawsuits in the US or other countries alleging unfair or deceptive data practices.
Industry impact: Other TV manufacturers may face similar scrutiny, leading to industry-wide changes in how standby data collection is disclosed or restricted.
