Samsung device care checks for caches throughout the system deletes them when you run it. It is totally automatic. It is supposed to do everything by one click on optimize now button .
Apparently they are not cleaning all the caches. Major apps like amazon , flipkart , google etc were all left out and when I checked manually the caches were there .
Why are they not cleaning these caches and why are they letting then keep it ? Device care is not letting them keep the caches so they have use that date for tailor preferred ads ? That's really sneaking behind customer's back.
I have attached the images before doing device and after doing device care . You can check the time on the screenshots to know the order wise.
Truly Disappointed.
