According to security research published by the YouTube channel Gamers Nexus, modern LG smart televisions continue to collect, store, and transmit audio and video content even after users explicitly disable automated content recognition settings in the menus.
Automated Content Recognition Bypasses Opt-Out Toggles
Automated Content Recognition (ACR) works by capturing brief six-second audio or video sequences to generate a text snippet, or hash, which database systems match against known media files, games, or broadcasts. According to Gamers Nexus, LG televisions continue transmitting a final tracking screenshot to Alphonso—operating as LG Ad Solutions—even after users turn off all privacy options within the device menus. Furthermore, the hardware sends an online beacon to LG during every system boot or network change. Hardware manufacturers increasingly rely on advertising revenue over initial sales, driving aggressive data capture across the entire lifecycle of the devices.
Microphones Listen Beyond Commands and RAM Logs Persist
Research led by Wendell shows that physical switches designed to disable built-in fernfeld microphones fail to stop audio capture, as connected USB peripherals, webcams, and remote controls continue recording sound. The television’s far-field microphone listens for up to 15 seconds after a voice command executes, capturing clear speech from up to 18 meters away despite manufacturer assurances that environmental noises are ignored. Additionally, internal RAM log files persist through reboots and are only wiped when the television is physically disconnected from power, while approximately 4 gigabytes of the 16-gigabyte flash memory remain dedicated to audio logging.
Network Proxy Risks and 50,000-Word Agreements
Intruders can exploit smart televisions as network proxies to intercept room audio via connected HDMI monitors during critical meetings, requiring only a brief network connection. According to the investigation, older LG television models received unrequested advertising IDs through firmware updates that cannot be disabled. Navigating the legal terms requires consumers to click through thousands of prompts across more than 50,000 words, where LG explicitly names Alphonso—which generated 192 million U.S. dollars in revenue during the first quarter of 2026—and Microsoft subsidiary Nuance Communications Inc. as service partners for data collection and voice processing.
Frequently Asked Questions
Do smart TVs record audio when turned off?
According to security researchers, televisions operating in standby mode continue recording audio data locally and transmit the stored logs to external servers as soon as network connectivity is restored.
Can disabling ACR in the menu stop data collection?
No. Research demonstrates that devices still transmit tracking data and final screenshots to advertising partners like Alphonso even after users decline privacy and content recognition agreements in the settings menu.
How can users completely clear television log files?
Clearing data through the standard TV menu only deletes server-side records. Physical disconnection from the power outlet is required to clear volatile RAM memory logs, though researchers doubt a standard factory reset removes all internal traces.
