The update is currently rolling out for the Korean version of the G7, but will likely make its way to other regions in the coming weeks. One of our G7 units in the office has already received the update so we've had the chance to test it out.
Unlike the regular 30fps 4K video mode that offers unlimited recording time, the new 60fps mode is limited to just 6 minutes, which is not all that surprising, as many other Android phones that support 4K@60fps are also capped at 5 to 6 minutes of maximum recording time.
You can enable the new video recording mode, once your LG G7 receives the firmware update, go to Camera > Settings > Video resolution, and choose the "UHD 16:9 (60fps)" option.
Other changes and improvements featured in the update, according to the changelog, include "improved sharpness when shooting in auto mode," a "Super Bright" mode for better photos when shooting with flash, improved rendering of the red and green colors (which LG phones have a history of going overboard with), and other tweaks and changes aimed at improving the overall user experience.
The 4K update is now rolling out for the Korean version of the LG G7, but should be made available in other regions in the coming weeks. For the full scoop on LG's latest flagship, check out our in-depth LG G7 ThinQ review.
