So long story short i switched to verizon i came from sprint and brought my phone with. since then i have not gotten updates on my note 10 plus SM-n975u is my model number. and i have february 1 2020 security patch. if i click the system update under settings it shows nothing and the verizon upgrade assisnant tool says my current firmware verison is not supported to update firmware. is this a bi product of switching carriers and bringing your own phone u get no updates? or is there something i need to do before i switched to verizon i did verify thru sprint that my phone had indeed been unlocked.
