[Samsung Galaxy S21 Guides, News] AllAboutTech:
He I will try to advise you how to optimise and debloat your phone for better performance and battery as well as free of bloat device.

I have used this method over the years for my S10 | S10+ | S20+ | S20Ultra | S21Ultra | P40 |P40 Pro and OP8 Pro and many other phones. And works as expected.

Prerequisites:

#1. ADB AppControl

Which can be found here:

https://xdaforums.com/t/tool-adb-appcontrol-v1-6-app-manager-debloat-tool-for-android.4147837/

ADB AppControl - android applications manager and debloat tool. Official website. Free download.

Thanks to @Cyber.Cat for this application of for posting it.

#2. Windows computer or for MAC owners, Parallel Desktop to run Windows

#3. Android phone which you want to optimise

Steps

for debloating bloatware:

#1. Download and install ADB AppControl from the above link

#2. Activate Developer Options: go to Settings >> About phone >> Software information >> tap 7 times on Build Number

#3. in Developer Options enable USB debugging mode

#4. Open ADB AppControl

#5. Connect your phone to your computer

#6. Allow USB connect message on your phone several times until ADB AppControl shows connect message on top

#7. Chose what applications you would like to disable or uninstall (i recommend you disable them not uninstall)

#8. From bootom right corner in ADB AppControl chose Disable option

#9. Check the box to delete cache and data [it is on top where you chosed Disable option at the previous step]

#10. Press Apply

#11. Confirm that you agree to disable the selected apps on the popup message which will appear

#12. Unplug your phone from the computer

#13. Shut down the phone

#14. Connect the phone again to your computer [being closed]

#15. Quick press Volume button + Volumne Up button until you see on your screen the logo

#16. Release the buttons

#17. Now you are into the phone recovery

#18. Chose the option to clear cache [NOT phone reset] with your power buttons

#19. Select the option to clear cache by presing the power button

#20. Chose restart phone

E voila.

There is no miracle bloatware list. It depends from phone to phone.

Being on a S21 series forum I will post what I debloated for my S21Ultra SM-G998B device.
