Unfortunately there doesn't seem to be a community for specific Samsung apps other than pay and a few others so here it is.
I have completely disabled sync of contacts from outlook in the Samsung contacts app and yet even after clearing all the storage for the contacts app and the contacts storage app and confirming that still my outlook contacts are not set to sync, the Samsung contacts app still goes and gets my outlook contacts anyway. I specifically prohibit that action. This is a major privacy flaw. I do not want those contacts brought to my phone especially since there are a number of other apps that might use them if I am not careful to check permissions from time to time
Once they have your contacts they sell them and do whatever they like with them. They build their own internal Facebook for ads etc. It's enough, it's 2021. People are sick of this!
Please fix ASAP else I will feel I have no choice except to contact the data commissioner.
