Galaxy Note 20 Ultra users are finally getting December security patch in the middle of the month. Sadly, it is not eligible for One UI 6 software update, but that will not stop it from taking new firmwares. Samsung has released new firmware code N986BXXS9HWL1 to the device. The other two siblings also have got the same treatment.
It is regular security patch with some known bug fixes and device improvements. The file size is 231MB, so don’t expect more from it. It is now rolling out in the US, Europe & India.
