S25 screen flickering after update to One UI 8.0

[Kardok]

So, I have updated my S25 last night to one Ui 8.0 and after that I realized that the screen won't stop flickering when I lock the phone, it endlessly turns on and off. I've tried every possible recommendation I've found (wiping cache, disabling adaptive brightness, etc) and nothing works, anyone else having this same issue that could give a hand?

Thanks in advance.

Does it happen in safe mode?

Contact Samsung support via Members app and let them deal with it

Yes, new Phone out of the box. Have tried with safemode same problem. Any way I can downgrade the OS version.

Update: problem solved. I had to perform a "factory data reset" and re install all apps one by one (tried making a restore from backup but this ended causing the same problem again). Apparently one of the apps was causing a conflict with the system update (although I never knew which was), But I did realized that there were some old apps that I had installed that didn't even exist anymore, perhaps this was the problem.
