The Samsung Galaxy S25 series launched with Log mode for videos, backported to the Galaxy S24 series with One UI 7 update.
Log videos can be recorded with all rear cameras but not the selfie camera yet, with evidence suggesting this feature will be added for older models with One UI 8 update.
Log videos require color correction before consumption, which can be done manually or automatically using the Gallery app's Edit suggestion feature.
The Log mode for the selfie camera is expected on the Galaxy Z Fold6 and Z Flip6, with uncertainty about its addition to the older Galaxy S24 series.
