Thanks a lot, I'll try it myself and edit OP.

Some of those apks on the block list just sit there and do nothing unless needed.
You need to know what you're blocking and if it really needs/should to blocked.
Dependencies, dependencies, dependencies, the app names and functions can be deceiving.
Samsung's have so many features you may never realize what you lost and for little or no gain.

The Google system and user apps are some of the worst offenders.

1- I have been uninstalling apps over adb for a long time now, and from a functionality standpoint, they don't interfere with the user experience, but on the contrary, uninstalling them improves the experience.
2- There are no apps that "just sit there", they all will consume power and resources on the background, only noticeable on the long run.
3- This is an extensive, maxed out and extreme list of bloatware, you can of course choose to skip some of those apps if you need them, your use case may be different then mine.

Many of those never load unless called upon.
You can see what's loading Device Care>memory or Developer options>running apps, cache apps.

Example; Bixby Vision and Bixby Framework.
The other Bixby crapware is disabled on my N10+'s. Those former two are not, and not loaded in the system cache or running. No need to block them. Karma Firewall also verifies no internet activity for them.

You're right, accessibility settings work now with samsung keyboard disabled but still installed. thanks, i'll move it to the "to disable" list.

 

[DannyynnaD]

Could you provide info of each app, so we know what are we going to delete \ disable?

You can use This app to check for package names, also, you can reinstall/download deleted apps using AppControl if you can't find them after debloating

 

[Ardysan]

Thank you for this - just tried this list, let's see how the battery life behaves now...

Akp Export shows the same but many of the Samsung system apks are anyone's guess. Android 10 (vs my older N10+ running on 9) on my new N10+ has dozens of new apks like this. Most of those shouldn't be touched as they are why the two N10+'s look and function almost identically. PD also list proper app names; it also has a direct browser search for each apk to try and see what its function is.

My Package Disabler list was imported from the older Note to the new one almost unchanged.
Surprisingly the optimization for the Android 10 variant was almost identical to the 9 variant, it was a snap. It took about 5 minutes to setup the PD app on the new phone, plug & play, and the user license (up to 3 devices) enabled seamlessly. One of the reasons I use it.
Makes factory resets easier too. It's nice to use a PD because you can troubleshoot with it, kill user installed apps that you occasionally use but don't want always running and you can easily test unknown or known apks to see what they do. I use the PD app daily for one thing or another. My favorite paid for app. If I lost it I be doing the abd edit thing.

@H-banGG So, after running suggested ones from the first post, Lloyds Banking app stopped working (app launch failed).

Any of the services can be causing this (security, Banking, authentication)?

Knox... maybe Samsung pass

These don't kill my bank app, but knox is still running...


Note: com.samsung.android.knox.attestation is NOT disabled on my device.

Hi, thank you for notifying the error. I don't use banking apps on my phone so i never had to face this issue, but i'd suggest first to restore all KNOX apps using ADB AppControl, restarting and trying again. Please, report back after.

 

[Ardysan]

Actually, kept Knox dead and just reinstalled the app itself. Works fine so far...
It probably restored whatever it needed during reinstall

 

[Ardysan]

Another curiousity.
Before "deep sleeping apps" - I could add apps to be put to deep sleep. No when I press + - there are none at all to choose there.
Is this because of suspend execution of cashed apps setting?

Yes actually, a lot needed apps are just needed installed, even if they are disabled

So, any ideas why it is not possible to put apps to deep sleep after making these changes?

In battery stats some apps have "background" activity and I'd rather they didn't . Used to work yesterday.

Hi, thanks for sharing this issue.
The "cached apps" setting in de options isn't actually the problem, there surely is a service that manages these sleeping apps that has been disabled, i'll dig deeper into that.
