[Debload][Bloatware] S21 | S21+ | S21Ultra or any flagship Samsung /Huawei /OnePlus phones

[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.

with the above done I always get 6hrs+ of SoT and battery live of over 1day and 10hrs in a single charge with 120hz WHD+ resolution

 

[miyuru4u]

Thanks for this method... I am using it with my S21 Ultra and works fine

 

[Arilan]

So, Im trying to figure out a way to safely disable the Samsung Dialer. Ive already installed the google dialer but I broke the calls when i uninstalled it the first time. Im trying to figure out which package is the one to disable. Trying to remove as much Samsung as possible

 

[galaxys]

Good to see this Debloat for the OnePlus, etc....

 

[deziderkovacs]

Excuse me, I´m totally new to the package disabling and I´m really looking forward to get it working on my new S21 Ultra. Could somebody please take some time, and explain to me what does it do and if the apps will still work even after disabling? (For example the bixby voice wakeup was disabled as seen in the screenshot, will my phone be able to get awaken via Bixby if it is disabled?)
Secondly I´d like to ask you if there is some sort of "best" list of packages to disable. I really want to maximize the battery life and performance of my device since it´ll be my inevitable workstation for couple of months.
Kind regards!

 

[lyzgaard]

If you are new to this and your device will be an inevitable workstation for a couple of months I would wait with the most crazy debloat.
You can only disable things you know of, if you disable bixby bixby wont work, at all.

Hi everyone, if I do an OTA update the process will reinstall debloated apps?

No.
You can double check by seeing number of installed apk in settings.
But I never had a problem with debloated app reinstalling.

Thank you very much!

 

[bluediablito]

Hello all, it has been sometime since I rooted my phone / removed all the extra crap lol.
Is there a way to know what each Items do?
I know in the past the roms would be debloted and you had a stock rom and had the option to add what you wanted.

Thank you

 

[AtrixBomb]

Nice start with original post. I'm also looking for any further explanation or categorization of s21+ bloat please?

If uninstalled, can app be reinstalled manually from play store if desired later?

What phone is best for clean customizable ROM now?
Guessing Pixel series, but what else... OnePlus?

I've custom rom'd my s3 to s8, but now want to have Netflix working on my s21. Just don't want apps I never use taking up space and populating the share menu options, etc.

 

[xkawsx]

does debloating drain battery?

 

[lyzgaard]

does debloating drain battery?

There are a couple of apk's who can drain battery if you deleted them.
I don't remember their name but if you debolat them the phone won't get into deep sleep....
But you can always double check if the phone enters deep sleep by installing CPU Spy from Play Store.

Just a little headsup on two packages you should NEVER disable!

• Device Services (com.samsung.android.kgclient) - If you disable this, you will LOCK YOURSELF OUT of your phone (Error 3020). Chances are good to recover from this if you have TWRP installed or USB debugging always enabled. Otherwise a factory reset is the only solution. Nevertheless, this is a core component and WILL cause problems if disabled.
• Device Security (com.samsung.android.sm.devicesecurity) - If you disable this, app installations will take significantly longer (about 5x). Not sure why, but better leave it.

In general, if you are not 100% sure what a package does, leave it! Even if someone on the internet says "I disabled it and had no problems"... There is a high possibility that you don't achieve optimization by disabling, but crippling your device and creating lots of errors in the background you don't know about (thus using more battery).

As far as I can tell, the list in the OP seems reasonable though.

@AllAboutTech Might be helpful for beginners if you add those 2 warnings to the OP.

 

[Lartsch]

You can always use ADB to re-enable apps, as long as you just disabled them (not uninstalled).

Connect to your phone via ADB and use the following command:
adb shell pm enable <package_name>
// Edit: I guess the ADB AppControl from the OP also allows to re-enable apps.

If you have uninstalled system apps, some of them might be re-installable via Play / Galaxy Store, but definitely not all.

Someone over at the S20 forums made a pretty good list some time ago:
Google Sheet

That's strange. I always delete both of these without any poblems.

Device Security it's part of the Macfee antivirus thingy options.
I always get rid of because I think Play Protect does the job.
When I delete this all that's happens is that the Security Option is gone from Device Care Settings.
And I don't get those anyoing security notifications about enable it.
No problem with app install.

As for kgclient that's part of the Samsung Payment Service, I have never had any problems with deleting it.
That said, I have never used Samsung Pay.

Im on S21 Ultra european model unbranded right now.

Hey, that's interesting. A friend also tested and confirmed the lock out / slow install.

Is your device encrypted?

No I haven't encrypted it, also I don't use Secure Folder.
Maybe this has something to do with Knox Vault on encrypted phones?
Samsung Pay is also a part of the Knox vault.
