[Samsung Galaxy Core Prime ROMs, Kernels, Recoverie] bogarty:
The list was for samsung galaxy devices in general, not just the s4. The s4 was just the newest galaxy phone at the time of the article I think. I found a lot of ones off that list though personally. Also, you can delete the MetroPCS apps. I deleted all except the Metro 411 app and MyMetro(bill pay app) because I do actually use those on occasion. I also use visual voicemail and allshare screencast stuff, so I didn't get rid of those either personally, but you can delete any of those for sure.

You might also take a look at this list here:

It's for the galaxy core(not prime) and you may find a few more there.

I also used some apps from the Play Store. Here are a few:

1) System App Remover(ROOT) - This is the most useful one really. It will show you all the system apps you have and will tell you, which ones you can remove safely and which ones are "key system modules" that it recommends not to remove, though sometimes it's wrong and you can actually delete those ones. Careful though, as generally it's right.

The best part about this app too is that any app you delete, isn't actually deleted right away. It goes into a recycle bin of sorts, which you can set to be located on your external sd in the app's settings if you want to save space still. Then, if you start getting system errors or popups or app force closes, you can just go into the apps recycle bin and restore which ever apps are causing the problem. If you delete something that causes you to not be able to reboot though you may have to restore your system backup in TWRP. If after a few reboots everything is fine though, then you can go and empty the recycle bin in the app if you want.

2) GS4 Lollipop Debloat(Root) - I installed this app and believe it or not it actually found some more apps that I hadn't deleted. It tells you which removable ones you have installed. It will show you stuff like Gmail, Google Maps and Youtube too, but obviously if you use those just don't delete them. Also, you can restore apps on there if there's any problem and it provides a brief description of what each app does before you delete too, which is handy. After deleting, then make sure to reboot the device. Anyhow, I've used this myself and it seems pretty safe.

Note: There are a couple of apps on the Play Store called "NoBloat Free" and "Debloater Free", but these apps basically just list all the same system apps as the first two I mentioned, but with less information about what you're deleting, so I would probably just skip those.

3) SD Maid - You'll want to use this one after getting rid of all your bloatware. It has a feature called "corpse finder" which will go through your phone and delete all of the leftover files from the stuff you deleted. It also has a lot of other features that help you clear even more space.

Anyhow, those are some of the things I've done and I hope this helps you guys trim the fat from your phone. Just be sure to remember that, if you don't know what something is, but you think you might want to delete it, it's generally a good idea to google it first to determine how important it really is. :)

EDIT: Here's another post too that attempts to explain what the different bloatware items are. Yes it's for the s4, but again there are a lot of the same system files there.
