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?

Obviously I will get OTA updates, I haven't seen any issues, Just got the old days battery backup and great camera performance back.

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.

Last version was - S918BXXU3CXCF

Your post does not apply to all devices and firmware you should update the post title or it is misleading.👍
