[Samsung Galaxy Tab A series Questions & Answers] AsItLies:
For those that want to slim down what's running on your 590 stock rom, this is a starter list I just created.

It's by no means comprehensive, let's hope people can add to it and we'll eventually have a good list people can use if they desire.

Please note, you are doing this at your own risk, meaning some packages, once removed, may affect the device such that it can't be booted! Then the only solution is to restore to factory defaults. So don't just go willy nilly uninstalling things without any idea what they do!

So the first thing I did was run:

adb shell pm list packages -f

This will list all packages and their associated file. There are additional options which show only disabled or enabled etc. But this gave me all I needed.

This next command will uninstall the package for user "0", since most of us only have one user with the device, it's all we need. Keep in mind, the package is still on the drive (taking up space), but it's not installed, so there won't be any notices about updating it etc.

adb shell pm uninstall -k --user 0 com.android.chrome

The above will (obviously) remove the chrome browser, which is something I always do, and install lineage Jelly browser. Just my preference - it's much more minimalist and I rarely use a browser on a tablet anyway.

** IF ** you do uninstall something and later want it back, one option (other than factory reset) would be the 'Solid Explorer' on the playstore, it can look at 'root' and reinstall packages.

Lastly, be sure to understand, I'm not telling anyone to do anything, you do any of this at your own risk. Don't blame me if you uninstall a package and then later it messes up your system. I'm merely suggesting this is something you can do, if you want to take on the risk.

That said, this is a list of packages I uninstalled using a linux bash script. My device booted properly afterwards and all is behaving normally, also I think it cut my installed apps almost in half! When I did the update to the latest security patch it optimized 66 apps! That's way too much for a minimalist like me, I don't need anywhere near that many apps installed.

Here's the list, again, use at your own risk;
