So I have been using the January G998BXXU4BULF for almost 24 hours now and it really greatly reduce the occasional stutter I have been experiencing (Exynos 2100) version.
There are animations improvements in all of this sections where I previously got intensive occasional stuttering
The last one was very very annoying - 3 from 5 times when I would go for my notification (swipe down on the home) to access notifications & quick settings my screen would stutter.
Battery is great as almost always, and I am only using max settings in terms of resolution + refresh rate (wqhd+ & 120hz).
I was not able to identify new changes in One UI home and Camera which got new versions, as this update was > 500 MB and security updates are ~ 250 MBs but it`s right about time for Samsung to fully optimize Android 12 (One UI 4) for S21 Ultra months and half before the S22 series is released...
Good to know that I was not the only one experiencing stutter on home screen / app drawer scrolling, Random app crashes and reboots.
Even the camera photo quality and google duo video calls have a lot more noise compared to pre OneUI 4 update.
I am suspicious if these are intentional, give the s22 ultra is launching without any major h/w upgrades
I have experienced one occasion of stutter on home screen / app drawer scrolling (had to reboot phone) and one random reboot with the January update.
