I'm currently on a debloat mission. I've searched but I haven't found a definitive list for the S5. My recommendation is to first 'freeze' rather thank uninstall apps and services (I'm using Titanium Backup). You need to be rooted for this. This way is you duff something up it's easy to unfreeze it.

Can anyone tell me what the following do:
ResetSecLauncher 1.03 (com.gmail.junk.trev.resetseclauncher)
ResetSecPhone 1.4 (com.gmail.junk.trev.resetsecphone)
ResetSyui 1.0 (com.gmail.junk.trev.resetsyui)
With Gmail in the package name you'd assume it's something to do with Gmail. I've frozen them but it doesn't seem to have affected Gmail.
There's a comprehensive list of bloatware for the S4 here
. I think anything in that list that is also on the S5 should be safe to remove/freeze.
