[Samsung Galaxy A20 Guides, News, & Discussion] jajk:
This requires a rooted phone.

The primary aim in this thread is to identify the functionality of the miriad of Samsung apps and those that can be safely removed.

All Google Play components can be safely removed.

It is the responsibility of all users to ensure they have backups of whatever they are deleting and the capability to restore them just in case it turns out to be a needed component....you have been warned;)

I highly recommend MyAndroidTools and SD Maid as useful tools to see what apps are installed, which ones are starting automatically, what can be disabled (frozen) successfully without the need to uninstall etc.

To get a complete list of what apps are installed, using a Terminal app, type su to gain root and then type pm list packages.

The output can be save to a file which will look like this:

:/ $ su
:/ # pm list packages

Some of these apps are self-explanatory, most are not.

sec is short for Samsung Electronics Corp if you are wondering;)

The above list is after Google has been largely removed and some Samsung apps uninstalled. I would appreciate a virgin list (before any debloating has taken place. Preferably from a non-carrier locked, June updated ROM.

No doubt there are similar threads for other late model Samsung phones with near identical bloat. If you find any good ones, add a link here.

I will try to build up a table showing the function and ramifications of uninstalling each app (with the help of fellow A20 rooters)
