OMG I had an idea but never realised that so many and I literally mean so many system apps/services could run in the background of Samsung Phone and that many system apps/services utilise mobile data in the background if not turned off manually. Manually disabling that many system apps/services from running in the background and from utilising mobile data in the background is a pain in back . 1 thing to note is that these system apps/services cannot be seen in the APPS SECTION IN SETTINGS.
