So after rooting you still end up with all these meaningless apps? Going through all the apps is a bit of a joke, what on earth are they there for? I can see when loading a new piece of software that certain apps are loaded to make the program run but most don't make sense. How does anyone know if there phising or malware, spyware etc!
Sorry for missing this post last week.
Rooting is simply gaining administrative access to your device. Let me use that (tire old) car analogy here. It's like having a separate set of keys to drive a car and get under the hood. Imagine if the dealer only had the keys to get at the engine/mechanicals so you couldn't work on your own vehicle. Rooting is like getting that set of keys. It just gets you the ability to do something rather than actually doing anything.
As I said before, once you have root access, you have the ability to get at your system files which can allow you to modify your phone in ways that the manufacturer or carrier didn't intend. This can either be a good thing for you or very bad if you break something.
If you've never rooted your phone and have only installed apps from trusted sources like Google Play or Amazon's app store, there's little chance you've got anything that's phishing or malware. If you have rooted and/or installed apps from untrusted sources, then you could be at risk. It's highly unlikely that a Samsung (genuine) phone would come with any malware or phishing apps, but if you're seeing that sort of thing, it might be browser based. Clearing your browser cache and app data, and then restarting your phone often times will clear up that problem.
If you want to remove apps, a better way to proceed would be to use an app like Titanium Backup to freeze the apps in question to see if it affects your phone. You can always un-freeze them. If you remove a system app, you can't simply uninstall it to restore it, you'd have to reflash the factory firmware.
As far as identifying apps safe to delete, that's going to vary between phone model, Android version and carrier, so it would probably best if you list the ones you want to get rid of and we can let you know if it's safe or not.
