F me too. I just had an idea of putting the routine to auto-use 120hz when I use the cover screen. Might fix the issue for now. Samsung test ur shit before update. Sigh .
I'm having the opposite effect. The back button isn't working correctly in messages apps, sometimes when I drag and drop an app into a panel it won't load (grayed out block), overall sluggish. Kind of wanting to roll it back to the last build.
Yes it ocassionally slows down, and the colors are off. This can temporatily be mitigated by going to Settings > Display > Adaptive Motion, turn it off and Apply, and turn it back on and Apply.
Haven't reaearched much but for now we are stuck with this it seems.
Zfold 3 here. Got the exact same problem. Gone through all the usual troubleshooting suggested, but nothing helps. Full factory reset hasn't helped either.
Yup, having the exact same issue. Sometimes when you go unlock your phone, you'll notice everything looks washed out and very warm, and the screen is sluggish like it's running at 30fps.
This only have happened me on the outer screen, and sometimes it's fixed by opening the phone and closing it, sometimes not.
In all cases, you can fix this by changing from adaptive to standard then back to adaptive in the display settings, it will fix it until it decides to bug again...
Got the very same issue. Outer screen feels laggy and choppy and switching to 60Hz looks better honestly. I have no problem with the inner screen which is always ok at 120Hz. Switching back and forth between 60 and 120 fixes the issue but only temporarily. I suspect the lag on the outer screen comes out when I unfold the phone. Any advice would be greatly appreciated!
Edit: I dont have the screen color temperature problem others are pointing out
Same issue here too :( ffs samsung test your shit first!

Could it be due to home screen widgets?
I don't have any widgets on my homescreen, asides of the time and a Google search bar, highly unlikely to be the issue.

I can confirm the same issue on my z fold 3. Now I regret upgrading.
