Don't update your Samsung Z Fold 4 to 6.1.1! It's a cursed update!!

My Samsung Z Fold 4 was good for both screen, until I update its firmware to the latest One UI 6.1.1. After I update it, my inner screen can't work normally. I must activate it by selfie cam (don't work anymore) or unfold it since booting.
The problem not only that. After boot up, the response seems laggy. And you can see there were screen glitch vertically. And if I click power button or fold it, the internal screen will never wake up, except I reboot in unfolded.
This laggy condition only happened on the inner screen. The front screen seems okay for the response & there were no screen glitch.
I think it's not a hardware problem. Some people said the problem is on ribbon connector but if that broken, my inner screen supposed death at all.
I have clean the cache on recovery mode & even do factory reset, both on recovery and by setting. After all these, the inner screen still same.
Doing some research, and I'm not alone. Many ZFold 4's user out there got the same problem after updating to Samsung's One UI 6.1.1. Some of them went to Samsung's Official Service & got no solution. One thing make it worse, we can't downgrade the firmware so it's like a curse because till now there are no update to fix this or even official explanation. So it's not exaggerated if I call it CURSED!

[@AlSatyr]

@@tohphu7081 Yeah, i found this problem too from another user. The solution was simple, revert back. But Samsung didn't open that solution just for Z Fold 4 & just mind their new product, foget about old customers. Damn Samsung!
