Motion photo capture

Samsung phones are the first to bring motion photos, and One UI 7.0 has enabled an extra option that lets you customize with “Before and after shutter” and “Before shutter only”. Yet, the camera app in the S23 series set to only one option by default.

Bixby UI

One UI 7.0 has redesigned Bixby’s home screen summon UI, including a screen expansion button on top and an input button on the right to type a query on the bottom side. A voice prompt button on the left helps you to start or stop the voice input. This UI looks better than the previous generation, which is still available in S23.

Natural Language Search

Natural language search utilizes the phone’s generative AI power for extra assistance in search. Users can go into Settings and say “My eyes are feeling tired”. The results will show you options such as adjusting brightness or turning on the Eye comfort shield.

For some reason, this feature is not part of the S23’s One UI 7.0 release.

Conclusion

The majority of One UI 7.0 shared between the Samsung Galaxy S24 and S23 are the same, but the ones that are missing in the latter model could be related to the chipset and image processing unit. Still, we can remain optimistic about a feature pack software update in the near future to add the missing capabilities on S23 models.
