Hi, thought this might be useful to users who are new to Android, or to other users who just got a phone with a new Android
This guide not only applies to S8/S8+ but to other phones that are higher than Android 6.0+
With this method you can remove apps that are by default unremovable If you try to manual removing them in the settings, aka. the bloatware that nobody needs.
For example, you can't remove Bixby Voice because it is part of the System, but with this method you can easily remove it. (I don't know if it completely removes it, but it won't be running in the background anymore)
So what do we do?
First we need to find out the package name of this app, you can do this by downloading System app removal, that has an option to view package names, aswell as the size of an app
We just found out the package name of this app, now we need to fire up ADB
You can download ADB from this thread: https://forum.xda-developers.com/showthread.php?t=2588979
If you installed adb systemwide, you can just bring up cmd, and enter adb
Note, that adb requires enabling USB debugging, otherwise it won't work!
in cmd type adb devices and press enter
You should see a message in your phone, just tap ok
Your PC now should see the phone
It should show random numbers and letters, next to device If you did it right
Note: You may need to type again adb devices If your PC didn't recognized it at first
For the next step we'll finally remove the said app
Type adb shell then press enter
You will see something like this, and now comes the removing part
If you wish to remove an app, you need to enter this:
And now I will remove Bixby Voice
Note: I already removed it, and it gives me this message, but I'll show you what happens
If you remove an app that is still installed on your phone
And that's it! These apps no longer exists on the phone
For proof I will show you that System app removal can't find the apps anymore:
Hope you find this useful
Note: Some system apps will reinstall themselves such as Bixby, there's no known method ATM on how to completely disable them
