Minimizing the App footprints, what i have been doing so far ...
This is not all done yet. I have more to learn. Any comments etc will be greatly appreciated. Unfortunately, i have not kept track of the amount of memory recovered. But for me that is not the main point. I want to learn the tech details of my device, and this process is accomplishing that.
 I have disabled and cleared data for these 13 Apps with no issues ...
Chaton, Dropbox, Flipboard, Hangouts, Tripadvisor,
Samsung [Link, Hub, and Books],
Google Play [Books, Games, Newsstand, Movies, and Music]
 I found an App that i think is very good for cleanup: CleanMaster and the 1-Tap Boost that it spawns, on Google Play, in the free utilities section. Anyone else use this or a similar app? What do you think?
 The following i expect to not use, are not in the App Manager, AND can be neither disabled nor uninstalled. I expect to hide these. Comments? ...
Group Play, [Google] Photos, [Google maps] Navigation,
[Google Maps] Local, Google Play Magazines, Story Album, Watchon,
S Memo, S Translator, S Voice, Voice Recorder, Voice Search
 I expect i should keep any in the App Manager list with the word "Services" in the name, altho i doubt that i would need either of the print services. Comments? ...
Google Play Services
HP Print Service Plug-in
Samsung Print Service
Samsung Push Service
 There is a list of App's that i expect to keep because i will be using them ...
calculator, camera, contacts, Rogers App Zone,
downloads, e-mail, gallery, 100% Games,
Help, internet, messaging, music, my files, phone,
[Google] Play Store, QuickPic, Samsung Apps,
YouTube, Google Settings
I am not at all into computer games, but i am keeping 100% Games in case there is a Saturday nite with nothing to do, bored out of my gourd, almost crazy. The Samsung Apps Free Utilities section may contain some useful apps. I am keeping Google Settings only in case some other app may need it.
 These that i do not expect to use, and that can be neither disabled nor uninstalled, i will hide ...
chrome, Google, Google+,
Samsung [account, InApp purchase, print service, push service, and Hub Updater]
 I am using some Widgets ...
Software Update, Google Search transparent version, Active Apps, Alarm
 I am uncertain about these voice apps, S Voice, Voice Recorder, Voice Search, and Google Text to Speach. Has anyone found these to be useful? Since they cannot be disabled i expect to hide them.
 I tried unsuccessfully to use "S Planner". I set in an event, requested 1 day notice by e-mail, no e-mail arrived. Tried again, same result. I do need a small, simple app for event/appointment reminders. Any suggestions appreciated, on either how to use this one or an alternative.
 I found a micro SDHC card on sale at BestBuy, 16 Gb, so bought it and installed it. So cheap i do not remember; about $16.00 i think [a buck a gigabyte]. I do not need it but there it is. Backed up the contact list onto it. And this phone will take 64 Gb! I'm an old computer bum from the '60s. Back then i programmed a 32K IBM 7040 and a 4K PDP-8 [that's K = 1024], the latter with a 10 CPS [Characters/bytes Per Second] paper tape reader for input, that cost tens of thousands of dollars and occupied full sized rooms - just like in the old science fiction movies from the '50s. Hard to believe this new stuff. So anyway, now i know how that works.
Let us know what you think.
