OK the title is self explanatory but lets go a bit further
I have two apps on my phone that I want to stop but primarily Facebook, I don't want them starting when the phone boots and I don't want them restarting on their own when I kill the process or stop the apps, I believe they have processes running that don't readily identify themselves as being associated with the apps so even if I kill/force stop the apps a short time later they just start up again.
I still want to be able to use the apps I choose so I don't want to uninstall or freeze them
The apps (for starters) are Facebook and ES file Explorer, I don't think ES FE is that bad and just stopping it from running on boot would be good enough but Facebook is an entirely different matter, it is extremely annoying.
Sometimes my phone heats up like it is doing a lot of work on something and when I kill facebook it all settles down
