A recent investigation by YouTube channel Gamers Nexus, in collaboration with Level1Techs and independent security researchers, has uncovered that LG smart TVs collect and transmit user data almost continuously. Tests on retail LG OLED models showed that these TVs scan local Wi-Fi networks for nearby devices such as phones and smartwatches, logging location information and details about surrounding networks. This data is then sent to LG Ad Solutions.
More notably, the TVs were found to record audio through built-in microphones even when in standby mode. This audio is stored locally when the TV is offline and uploaded once an internet connection is restored. Additionally, LG TVs employ Automatic Content Recognition (ACR) technology, which analyzes audio and video inputs—including HDMI sources—to determine exactly what content is being watched. This data is used to track app usage and viewing habits.
While ACR is a common feature across many smart TV brands, the extent of LG's data collection, especially during offline and standby states, raises privacy concerns. This is not the first time LG has faced scrutiny over data practices; earlier this year, Gamers Nexus reported that some LG monitors were installing apps that collected device data and displayed unsolicited advertisements. Following public backlash and intervention from Microsoft, LG disabled these pop-up ads.
The findings highlight ongoing privacy challenges with smart home devices, emphasizing the need for consumers to be aware of how their data may be collected and used, even when devices appear inactive.
