webOS 26 Arrives on LG OLED G5: The Start of the 2025 TV Update
LG has begun its move to apply webOS 26 to TVs from previous years. After being first introduced in the 2026 TV lineup, the Korean company LG has started distributing the new version of its operating system to some older models, with the first beneficiary being the 2025 LG OLED G5.
While we already knew this would happen through the webOS Re program, it's now actually happening. The rollout started with the G5 and will likely expand gradually to other models and regions, as LG usually does.
Moreover, this is not just a small update with four minor revisions. webOS 26 changes several parts of the system, introduces new features, and takes up about 2GB of space. The firmware appearing for the LG OLED G5 is version 43.21.71, but it may still take some time for the automatic notification to appear on your TV depending on your country.
webOS 26 Offers a Faster Interface and New AI Features
One of the major changes LG promises with webOS 26 is the speed of the operating system itself, something we use absolutely every day. The company talks about a faster experience, along with changes to various parts of the interface and the introduction of new AI features.
A redesigned Home Hub is also included, featuring integrated Homey functionality so you can control smart home devices from your TV. Added to this are a new Kids Mode and improvements to the AI-based search function, helping you find content directly on webOS more easily.
Another interesting point is the Gallery, where webOS 26 adds AI-powered image generation. Of course, some functions that previously existed, such as ColourSpace and bscpylgtv options used for color calibration, along with 360 VR content compatibility through the web browser, will be removed with this update.
G5 to Be Followed by OLED C5 and More Models
LG is rolling out the update sequentially, and the G5 is just opening the way. In this type of update from the brand, it's common for the C series OLED to be next, followed by some high-end LCD TVs and B series OLEDs.
And right here is one of the advantages of the Re program. webOS 26 will not stay limited to 2025 models. Compatible TVs from 2024, 2023, and even 2022 should also receive this new version, but you'll need a bit more patience in those cases. The rollout is expected to happen gradually throughout the rest of 2026, and for some models it may even extend into early 2027.
If you have a G5, you can check for this update in your TV's own update menu. In some countries, LG also allows you to manually download and install firmware 43.21.71 via a USB memory stick, which is an interesting option for those who don't want to wait for the automatic update.
Be Careful, You Can't Go Back to webOS 25
Before pressing the update button with a joyful heart, there are some important details you should know. Once this version is installed, it's impossible to revert back to webOS 25. This means that even if you later discover you prefer the previous interface or can no longer use certain specific functions, this update does not allow for downgrading.
LG has also started distribution much more smoothly than last year. The webOS 25 update for older TVs began rolling out around late September, but webOS 26 has already been arriving since August. Currently, the G5 is the first runner, but over the next few months, we will see a significant increase in the list of compatible TVs.
According to LG Electronics' webOS Re:New program, here are the main changes and detailed information for the webOS 26 update applied to 2025 models.
Major Improvements and New Features
• Improved system performance and speed: The responsiveness of the interface has been improved for a more enjoyable experience.
• Home Hub (Home Hub) revamp: Smart home integrated control functions have been strengthened, with additions like Homey integration. This makes controlling appliances and IoT devices through your TV even more convenient.
• Enhanced AI and personalization features:
• Introduction of the AI Concierge feature, which provides personalized content recommendations and tips.
• Improved AI search functionality and addition of AI image/music generation capabilities within the gallery function.
• Kids Mode (Kids Mode): A new mode has been created that safely restricts content and interface access for children's viewing.
• Minor usability improvements:
• Channel switcher design update
• Improved internet browser bookmark and zoom control functions
• Added an option to directly control soundbars or external speakers through the TV's audio settings menu.
Cautions and Exclusions (Checkpoints)
• Discontinuation of calibration tool support: There have been reports that the connection and access to some professional calibration software (ColourSpace, bscpylgtv, LG White Balance GUI, etc.) are blocked or not working properly in the webOS 26 environment. Users who frequently calibrate image quality using such equipment often choose to postpone the update.
• Removal of browser features: Support for 360-degree VR content playback in the internet browser and media player has been removed.
• Downgrade not possible: Once upgraded to webOS 26, it is impossible to revert back to the previous version, webOS 25.
• Initial stability issues: Some users have reported temporary friction in eARC or external device audio output (such as PCM fixation for some codec playback) immediately after the update. Therefore, it may be advisable to apply the update after confirming that the official OTA package has been fully and stably implemented.
※ Additional changes confirmed by reports
• Added direct option settings for SoundSweet
• Added HDMI change button designation function to the remote control.
