I can't seem to find anywhere in the settings for a clear cache button! I find a button that says optimize now, but it doesn't clear cache when clicked on! I found my app mgr. 3 app will clear my cache so I get it done that way for now but am I missing where this setting is?
The newest version of device care doesn't clear the cache anymore. You ne3d to ho into settings/apps/device care, click on the three dot menu, and select 'uninstall updates.' That will restore the cache cleaning function. You will need to disable automatic updates in both Google play and Samsung Galaxy store to keep this function from being removed in a new update.
