[Samsung Galaxy Tab S3 Questions & Answers] JackieBlue:
Picking up where I left off with my original post, I soon discovered Terminal Debloater developed by Magisk (a means of removing apps systemless-ly!).

OneClickRoot didn't advise me of that method (and still hasn't gotten back with me, incidentally). Of course, they do make money selling extended support packages (and it's worth noting that they didn't flash TWRP to my device either).

I thought if Terminal Debloater didn't do it nothing would. And it didn't work, even though I didn't uninstall Google, Google Play Services or Google Play.

I mean, it got rid of the apps just like ES File Explorer did, but my device once again became nearly unusable (unable to open Google Play Store or Amazon Appstore among other features of my device). But systemless-ly? Not so sure about that.

Resetting the device remedied the problem(s) and reinstalled everything without requiring a re-root (minus 3rd party apps that I already had installed, of course). I had forgotten about the previous backup that I had performed with Titanium Backup but it was like 4am and I was getting foggy, you know - there have been a lot of late nights lately. My device was still rooted after the reset and I was able to reinstall Magisk Manager with an .apk (Google Play Store banished it). Maybe that's what they meant by systemless uninstall - the relative ease of reinstall.

So I think that after all of this experimentation it is fair to say that unless you have goals other than uninstalling meaningless stuff like that withTV app it isn't going to work out. And for an app freezer/disabler to work properly you need a root. And an app/freezer disabler won't disable them all. I still have a lot of Google apps it won't disable like Gmail, Chrome, Photos, Movies & TV and Google Play Music (although I realize most people aren't interested in disabling Google apps). I could probably safely remove YouTube, Maps and Drive (I was only able to partially able freeze the former but I was able to fully freeze the latter). There are others I could probably uninstall too - OneDrive, other Microsoft apps, Weather, etc. - it would just seem pointless though since they are already frozen. So maybe freezing is a good enough reason to root for those who only want minimal removal of apps and still want Google where the sun doesn't shine.

Anything that can be frozen can probably be safely removed with the root but I haven't experimented with that. It might require a 4th reset and/or reroot. But you will never have total freedom to do what you want.

As far as OneClickRoot, it is fortunate that I paid with PayPal because I am going to file a claim based on many factors. They asked me why I was rooting my device and I told them I was going to remove apps. They didn't advise me on that either way. They didn't tell me that the root would trip Knox. It says on their Galaxy Tab S3 page, "After the rooting process is completed and done, you may start installing carrier-blocked applications" "you may positively eliminate preinstalled crapware" and "Remember that after rooting, you are the administrator of your own phone so have the freedom to do anything you want with your phone." If they made the mistake of referring to a phone on their tablet page then that's their bad. I do not yet qualify to post links on this forum, but you can find the page by using DuckDuckGo to search "Galaxy S3 Tab OneClickRoot" and it's the first search result).

I paid them $60 total to root my device; the first time I thought I removed too many apps and that it was my fault so I paid them an additional $20 to re-root it. Turns out it really wasn't my fault at all because with the 2nd root I uninstalled even fewer apps than the first time (and like I said before, never any core system apps or even any major android apps like Google Play Services). I figured out how to unroot it on my own (with firmware files from SamMobile and flashed with Odin) and then screen recorded the 2nd root.

At the end of the day I'm not sure it's really worth it to root just to remove a few apps and void your warranty if you're still covered (I have only owned my device for just over a week).

But then, not everyone has the same objectives I do. I am completely crazy serious when it comes to my privacy. One might ask why I even purchased this device and it's because it affords customizations that Apple doesn't (or so I thought). But I can still run Linux. And, of course, I have no intent of setting up a Samsung account or a real Google account. I bought a cheap sim card from TracFone to use with my old S3 phone to set up a fake Google account (because of course you have to have a phone to register a Google account). My TracFone account is under a fake name, my phone number has a Chicago area code (I live across the country), my Google account will be under a fake name and I use a paid VPN on my device(s) using a Chicago IP address. They deserve it.

All just so I can get a few paid - but important - apps. If it weren't for that, Google account be damned. I sold my black little soul to Amazon a long time ago but their selections are limited.

Oh, and for those who aren't rooted and simply want to uninstall system apps for more space, you can force 3rd party apps to SD by enabling that feature in Developer Options.

Go to Settings > About tablet > Model number > Software information

Click on Build number 7 times. That will activate Developer Options which you will then find at the bottom of the column on the left side.

Click on Developer Options and scroll way down to Force Allow Apps on External.

Then scroll up to Running Services and observe what's going on behind the scenes. Especially if you have denied (and even frozen) location permissions, deactivated bluetooth, limited background processes to "none" and deactivated automatic updates. They will grab at ANYTHING - your bluetooth, phone, etc. You can stop the processes but they still keep coming back. It's fun to give them an occasional punt anyway.

I did manage to finally disable blutooth but that *had* to be frozen. Disabling in settings wasn't good enough. Google Location Service cannot be stopped ever.
