LG’s smart TVs are among the devices that can do much more than just display TV programs. Streaming services, voice commands, and personalized recommendations have long been standard for many users. However, a recent investigation by security researchers raises questions about data handling. According to their findings, the TVs collect significantly more information than many users would expect.
For the analysis, Gamers Nexus, Wendell from Level1Techs, and other security researchers examined the manufacturer’s smart TVs. According to them, the devices not only gather information about TV usage but also data from the home environment. The results suggest that data collection could be more extensive than previously assumed.
Researchers see issues even in standby mode
During their investigation, the experts found that the TVs can recognize and analyze connected devices in the home network. According to the researchers, this includes smartphones, laptops, smartwatches, and thermostats. Additionally, the devices are said to be capable of capturing information about private conversations.
According to the researchers, this is possible not only during active operation. Their tests indicate that such data collection can also occur partially in standby mode. The collected information is then used to deliver personalized advertising.
Voice control and content recognition in focus
The researchers are particularly critical of the handling of audio data. While voice control is intended to make TV operation easier, the testers believe it could also contribute to data collection.
Additionally, the devices use automatic content recognition, also known as “Automatic Content Recognition” or ACR for short. According to the researchers, this feature analyzes users’ viewing habits. The system can even detect which content is played via HDMI on the TV.
Temporarily disconnecting from the internet is not enough to permanently prevent data transmission, according to the experts. They found that the device stores the information locally and transmits it later once an internet connection is reestablished.

Security vulnerabilities discovered in webOS
In addition to data collection, the experts reported finding vulnerabilities in webOS, the operating system of LG smart TVs. The researchers warn that attackers could potentially exploit these security gaps.

In the worst-case scenario, cybercriminals could gain access to the devices’ microphones. The investigation highlights not only privacy concerns but also potential security risks.
LG disputes the allegations
LG rejects the security researchers’ allegations. According to the company, the TVs do not collect or store conversations from their surroundings. LG also emphasizes that voice recognition can be used voluntarily and that data is only processed when the feature is actively used.
To limit data collection as much as possible, users can permanently disconnect the TV from the internet. Alternatively, using external streaming devices is recommended.
