LG TVs found to collect data even when not in use or offline.

LG smart TVs are reportedly always collecting and transmitting data about their users and surroundings, even when they’re offline or in standby mode, as highlighted by a recent investigation from a YouTube channel. These TVs actively scan local Wi-Fi networks for nearby devices, capture audio through their built-in microphones, and utilize audio and video sampling to identify what content you’re viewing across different inputs.

The investigation involved testing retail LG OLED models in collaboration with other YouTubers and independent security experts. Packet captures revealed that the TVs were scanning the local network for devices like smartphones and smartwatches, logging location data, and gathering information about nearby Wi-Fi networks, which was then sent back to LG Ad Solutions. Alarmingly, the TVs could also record audio through their microphones while in standby mode, continuing this even when disconnected from the internet. The audio files were stored locally and uploaded once the TV reconnected.

A key aspect of this issue is Automatic Content Recognition (ACR), a technology that analyzes audio and video data to determine what you’re watching. It assesses the apps you use on the TV’s smart interface and the content connected via HDMI and other ports. However, ACR isn’t exclusive to LG; it’s a common feature among nearly all smart TV manufacturers, as explored in another recent video.

This isn’t the first time LG has faced scrutiny from the channel. Earlier this year, it was reported that some LG monitors were automatically installing an app that collected device data and displayed pop-up ads for LG’s other applications and even antivirus software. The backlash from that video prompted Microsoft to step in, resulting in LG disabling the pop-up ads.
