Samsung could bring one of the Galaxy S26 series’ notable camera features to its previous-generation flagship smartphones. According to a report by GalaxyClub, the Horizontal Lock functionality is available in the internal build of One UI 9.
This particular functionality is currently available on the Galaxy S26 family. The reported software test suggests Samsung may expand its availability to at least some Galaxy S25 models through a future software update.
It will enable Galaxy S25 owners to access an innovative video stabilization solution without buying new equipment. However, Samsung has yet to provide any official announcements.
Horizontal Lock aims to keep video level with the horizon despite the user moving and tilting or rotating their smartphone while recording video. In addition to using data from the phone’s gyroscope, the function uses image processing techniques in the software to ensure that the frame remains leveled.
It also uses extensive digital cropping as a means of compensation for movement. This gives more space inside the frame to stabilize the images and creates a gimbal-like effect while recording videos.
The function appears to be associated mainly with Super Steady Video Recording. It might work only under particular resolution and frames-per-second constraints, with reports indicating 4K resolution and 30 frames per second being supported.
The current discovery comes from an internal One UI 9 test build carrying firmware version DZG4. An X user with access to a Galaxy S25 Plus reportedly found the Horizontal Lock option working on the device.
The discovery does not confirm that the feature will appear in the final public release. There may be changes to the feature during software development. The company has also not provided any assurance that the feature will make it to all versions of the phone.
There may be different levels of support for this particular feature for the Galaxy S25, Galaxy S25 Plus, Galaxy S25 Ultra, and Galaxy S25 Edge based on the capability of the cameras on these models. The test found here applies only to the Galaxy S25 Plus.
