I have a 256GB S23, and One UI 7 actually works very well. I haven't had any issues. I think it's all due to the SD8 gen 2, which was, for me, Qualcomm's best processor. I hope this new version of One UI 8 brings many new features in artificial intelligence to help it compete with the competition.
The Galaxy S23 series of premium smartphones is now 2 years out of date; however, Samsung is already working on a major software update for the line, according to a new leak. It asserts that devices from the range have been spotted running an upcoming version of the OEM's One UI based on Android 16.
