Thank you so much for replying! i have factory reset the phone a million times and still the same thing. i find all my settings setup for casting, and anything to do with connecting with another device is always turned on without me doing it. such as nearbyshare, cast options in google settings device has turned itself on from hidden to visible, chrome settimgs auto sign in turned on, all my wifi control apps are permanently turned on, google location turns on, nfc always turns on as soon as i turn on the phone, wifi calling always turns on as soon as i turn on the phone, smart things turn on, printer is turnedoin, bluetooth is turned on in google app, ALL WITHOUT ME DOING IT. Theres more but i cannot remember So that's how i know. When i turn them all off some of them turn themselves back on. I could not even update my software umtil i joined samsung. So much bother. Also all the apps with certains connective settings are permanently on. I cannot even turn them off. ETC... The apps in googleplay will say the apps were not downloaded in googleplay when i uninstall etc.
