That's not good @dowloading90
As a very last resort it maybe an idea to backup and factory reset and or send a bug report via the Samsung Members App / Samsung + app along with log files.
Current Phone > Samsung Z Fold³ 5G.
I have noticed that this happens sometimes when I wake up the phone after it was put to sleep for a while, it lags for about 10 sec in the home screen before it goes smooth again
In my case, I suspect that the culprit might be my Spotify app. It started to behave weirdly since I upgraded to One UI. Everytime I restart my phone the app resets my storage path from SD card to internal storage, causing it re-downloading all my downloaded songs in the background. I dont know if this is a main reasong causing the lags but after I uninstall and re-install the Spotify App the laggy problem does get better. Finger cross that it stays in this way from now on.
could it be that some icons are not optimized for One UI Home Launcher? Or maybe can you try removing all the existing Icons on Home Screem and create them all again from the app drawer? See if that helps.
