Have you face any problem after downgrading one ui 5.1? And do you feel the overall perfirmence is significally better compare to one ui 6 or 6.1? And will you able to ota update via samsung server in future?

You would not have installed any security patches after the OneUI 6.0 update, cause then you can never downgrade back to 5.1. If SW.Rev number higher in the upgrade you can never downgrade to a lower version.  Please provide details of last 6.0 build before you downgraded then we can accept your solution.
