LG’s latest wave of OLED smart TVs are under fire after a deep-dive investigation found they continue cataloging your devices and recording microphone audio even when the screen is dark and the set appears to be “off.” Hardware channel Gamers Nexus, working with Level1Techs and multiple independent security researchers, dissected retail LG OLED models including a 2025 LG G5 and concluded that the TVs behave less like passive displays and more like always-on surveillance appliances embedded in the living room.
The team’s packet captures and firmware analysis showed LG TVs aggressively scanning local networks, enumerating phones, PCs, printers, switches, smartwatches, and other smart-home devices connected to the same router. Test units also logged nearby Wi‑Fi networks beyond the owner’s SSID, including network names, signal strength, and channel information, effectively building a partial map of the wireless neighborhood around the home. In one case highlighted by coverage, a single TV detected at least 38 devices on its Wi‑Fi network and recorded details such as internal IP addresses, device names, and even usernames associated with certain hardware.
Beyond network snooping, the investigation documented LG sets capturing and processing microphone audio while nominally in standby, with the panel dark and the user believing the TV was idle. Researchers reported that once voice recognition features were activated, the TV continued ingesting nearby conversations and transforming speech into plain‑text logs that were stored locally, sometimes even after the television had been disconnected from the internet. When connectivity was restored, those cached transcripts and audio files were automatically uploaded to remote infrastructure associated with LG’s advertising arm, LG Ad Solutions, raising fears that sensitive household chatter could be funneled into a marketing data pipeline without meaningful informed consent.
The scale is what turns this from a niche infosec curiosity into a mainstream privacy crisis: Gamers Nexus framed the issue as “216,000,000 Spy TVs,” referencing LG’s global smart TV install base and arguing that every set could be quietly reporting on “everybody in the household.” Multiple write‑ups stress that the TVs’ device discovery, Automatic Content Recognition across HDMI inputs, and continuous telemetry start to resemble malware, especially when combined with security weaknesses that could let attackers hijack the hardware as covert listening posts. Some security commentators have even flagged demonstrations where exploitation allowed a TV to capture audio from a connected USB webcam while the microphone kill‑switch appeared inactive, blurring the line between manufacturer data collection and outright surveillance risk.
This is not LG’s first run‑in with smart TV privacy alarms. Back in 2013, the company was caught collecting viewing data and even reading file names from USB or networked drives, sometimes continuing to transmit that information even when users had toggled off the “collection” setting in the menus. After public backlash, LG promised a firmware fix to stop sending data when users disabled the feature and to strip out the USB file‑name logging altogether. The new revelations suggest that in the decade since, the broader smart TV industry has moved from crude channel‑logging to far more expansive profiling, tying unique households, devices, and viewing habits into sophisticated advertising and analytics platforms that look a lot like what phones and browsers already do—only now from the biggest screen in the house.
For gamers, home‑theater geeks, and remote workers who use high‑end LG OLEDs as monitors, the findings hit close to home. A TV that inventories every console, PC, router, and VR headset on your LAN doesn’t just raise abstract privacy questions—it potentially exposes a detailed map of your entire setup if that data is ever breached, misused, or repurposed. Reports also warn that these behaviors persist across inputs, meaning the TV can track what you watch on a Blu‑ray player, game console, or streaming stick even if you avoid LG’s built‑in apps, undercutting the notion that “just use HDMI and ignore the smart features” is a safe workaround.
So what can LG owners do right now? Short of retiring your smart TV entirely, privacy‑minded users can isolate the set on a separate VLAN or guest network, avoid signing in to manufacturer accounts, minimize voice assistant usage, and treat the TV more like an internet appliance than a dumb screen. Physically disconnecting network cables or Wi‑Fi will at least prevent uploads, though the investigation shows the hardware may cache logs locally for later transmission, underscoring how incomplete that defense can be. Security bloggers have also pointed out that, in the wake of early coverage, LG quietly updated its terms with forced arbitration language, which could make it harder for angry customers to band together in court. Until regulators, standards bodies, or class‑action pressure force clearer boundaries on what “smart” displays are allowed to collect, the safest assumption for geeks and civilians alike may be to treat every connected TV as a potential surveillance device—and architect your home network accordingly.
