The feature list provides clues to the new functionality
The aforementioned leaker, who has a penchant for French flagship thieves, also left us a screenshot of the feature list for the Galaxy S24 Ultra and Galaxy S24+, which provides some interesting details, although nothing that previous leaks haven't already hinted at. Meanwhile, it is also known where this leak comes from. Walmart has a bunch of Galaxy S24-only product pages already, For example here.
According to this, Samsung will promote the new “Galaxy S24 Ultra” phone with the Nightography Zoom function, which is supposed to provide better zoom shots in low light based on the new 50-megapixel telephoto with 5x optical zoom. It remains to be seen why this feature is also included in the Galaxy S24+ even though the camera will be similar to that of the Galaxy S23+. Samsung may have improved the quality of its AI algorithms.
Both Galaxy S24 models will also benefit from several other AI functions, such as Live Translation, i.e. real-time translations, and “Global Editing”, which is essentially a version of the Magic Editor for Google Pixel 8 and Pixel 8 Pro users. However, as with the latter, cloud access is required, so AI-powered photo editing directly on the device doesn't seem to work with Samsung phones either. There have also been mentions of brighter displays and, in the case of the Galaxy S24 Ultra, flat displays; It appears that photos can now also be shared at a higher resolution.
