I used the app Package Disabler Pro+ (Samsung) by policedeveloper available on Play Store here https://play.google.com/store/apps/d...g.batteryaddon
But for those with better skills and a computer, using adb's 'pm uninstall -k --user 0 <package name>' is an option, too.
IMPORTANT: You won't really know the true effects of your disabling til you restart the tablet! On the other hand, it seems that undisabling (re-enabling?) takes effect immediately.
I did a web search and found an .xml file that had packages disabled on a Galaxy S10 or S8. Unfortunately I don't remember from where I got the file but this and other files are available in my shared pCloud folder https://bit.ly/2VXRoLt You'll find below files, among others, there:
disabledpackages-Package Disabler Pro+ DEFAULT ALL BLOATWARE-46ofthem.xml
>>The default packages using 'Disable all Bloatware' option in Package Disabler Pro+
>>The file I found. When I used this the tablet UI slowed to a crawl. From my previous experimentation I suspected that disabling the phone apps was the culprit. I was right, and am currently using my tablet without any discernable issues using the xml file below. Obviously, examine the file before using it to see if it fits your needs. For instance, I don't use Bixby, so I disabled it.
[EDIT] File deleted.
>>The file I exported from Package Disabler Pro+ after reenabling some packages.
[EDIT] Replaced by disabledpackages133-OK.xml
Below are the packages I reenabled in order to get the tab back to 'normal'. I'll continue with experimentation to see which one(s) are causing the slow-down, and report back here.
