A smart TV is now one of the most connected computers in a home: it sits on the local network, runs apps, may use a microphone for voice controls, and can tie viewing behavior to advertising systems. That makes new claims about some LG OLED TVs worth watching closely, even though the available testing does not establish that every LG TV behaves the same way.
Gamers Nexus, Level1Techs, and independent researchers examined network traffic, firmware, and retail-purchased OLED sets. Their findings include allegations of local-network device discovery, nearby Wi-Fi data collection, and potential security vulnerabilities. LG disputes key interpretations of the tests, particularly the suggestion that its TVs capture ordinary room conversations.
What the researchers reported
The reported behaviors span both expected smart-TV capabilities and more consequential privacy and security questions. Researchers said the tested sets could identify devices on a local network, including phones, PCs, printers, and other connected hardware. LG acknowledges device scanning, characterizing it as a normal function for smart TVs and smart-home equipment.
- Researchers alleged that the TVs collected information about nearby Wi-Fi networks and device-associated identifiers.
- They said automatic content recognition, or ACR, could analyze audio and video to identify what is playing, including material delivered through HDMI.
- They reported observing microphone-related audio data while a TV was in standby mode.
- In tests without an internet connection, some information was allegedly retained locally and sent after connectivity returned.
- They also reported remote-code-execution vulnerabilities to LG. Technical details have not been made public while responsible disclosure remains underway.
ACR technology has long been a sensitive subject because it can be used to recognize programming and advertising viewed on a TV. LG says its ACR system is optional and that its associated data is not used for advertising without the user's consent.
LG says voice processing requires activation
In a statement to The Register, LG said voice processing occurs only after someone presses the dedicated button or after the TV detects “Hi LG” when that wake-word feature has been enabled. The company said that outside those situations, its TVs do not collect or record ambient conversations.
That distinction matters. A designed data-collection feature, a potentially exploitable vulnerability, and behavior observed under a particular test setup are not interchangeable claims. The public reporting does not provide enough information to determine whether the alleged audio behavior can be reproduced across models, webOS versions, configurations, or regions.
Why connected-TV privacy remains a U.S. concern
The debate extends well beyond LG. In 2017, Vizio reached a $2.2 million settlement with the Federal Trade Commission and the state of New Jersey over allegations that it collected viewing histories from roughly 11 million TVs without informed consent. ACR technology was central to that case.
For households that use a TV alongside tablets, laptops, phones, game consoles, and other connected gear, the immediate takeaway is not that every LG TV is secretly recording the room. It is that privacy settings, voice-assistant controls, ACR permissions, and software updates deserve the same attention as picture modes and streaming apps. More model-specific detail from the researchers and LG will be needed to resolve the outstanding claims about standby-mode audio data and the reported security flaws.
