1. december 2020, version N985FXXS1ATK1

I updated the phone on 7. December around noon, and after the update the phone keeps rebooting.
After it boots up, it seriously laggs. It then shows the notification "finishing system update" which after it reaches around a fifth of the progress abr, the phone reboots.
But it is not a real reboot, it only shows the Samsung logo for a couple of seconds and jumps back to the home screen, lags again and the notification starts from the beginning.
The phone's uptime is aorund 15 seconds before it reboots. This was a standard OTA update, no bootloader stuff, no nothing.
I'm taking it tomorrow to store.
I've tried:
- reseting network data
- wiping cache from the boot menu
- booting into safe mode
No difference.

Has anyone else experienced this, or has any advice?

Dud motherboard if you have exhausted all software troubleshooting options. Had a sm-n985F with similar issues. Random reboots.
Does not have to be motherboard issue.

updates through OTA can get corrupt/damaged so your update mostlikely got this so it reboots all time.

Try reinstalling your phone via smart switch app on pc or ODIN and see if problem remains.

If it stops then it was due to corrupt/damaged files in update via OTA.

Hence why I mentioned if you have exhausted all software avenues.
