@chaosppe speaking from my personal setup, I'd do all of these but personally my way to prevent as much data harvesting from Samsung phones I also installed Netguard and set only a handful of apps and exclude the rest (even system one) to stop all these Samsung apps from transmitting all types of data (Yes I know this may be somewhat extreme and I know the limitations of Netguard), but hey it's just my recommendation but maybe you can take this as a possible starting ground
