Edit system files non-rooted? - Samsung Galaxy A50 Questions & Answers

Hi there,
My A50 is my only non-rooted device (job/work device) and I feel my hands tied :crying:
Can I use adb to edit system files (ie. enable call recording) without tripping knox or kill the "original/unmodified" classification of the device?
thanks in advance

How to remove Private Mode from settings...

Hi
I just ROOT my tablet (SM-T800) all works ok plus some things much better but probably because Knox flag 0x1 Private Mode (or Personal Page Service - don't know proper English name for it) not working.
How can I remove that from settings (Hide it) - or maybe there is a chance to fix that (make it work with root and flag 0x1)
Thanks
EDIT
Its OK I found what's needed HERE Thanks

User profiles on Galaxy S9?

Would anyone know if the Galaxy S9 natively supports user profiles so that multiple users can login and use the same phone with their unique settings and apps? If not would anyone be able to recommend an application that could accomplish this?
The functionality has been disabled for stock Samsung ROMs long time ago (if it was ever enabled). There were some discusions in the past regarding this and what I remember is that you need root for this to work. You have to edit build.prop and include the lines:
fw.show_multiuserui=1
fw.max_users=n (where "n" is a number indicating the max users on device - should be at least 2)
Alternative is to flash an AOSP based ROM that has the function enabled.

I unfortunately cannot root the device as it will be provisioned for company use :/ is there a launcher that could help to accomplish this?
Sorry, none I know. The functionality is deep embeded in the OS, a launcher would not be enough to accomplish that
You could however use dual accounts for certain apps or mail and also use Secure Folder to lock out personal/private data. This way you will have some sort of multi user since the secure folder keeps data in separate encrypted form

About enabling Camera2api without root/unlocking bootloader

Hello, Mi A2 lite is under Android One project of Google, you know!
However,
My phone has Miui Camera app by default. But I don't like it that much. I want to use 3rd party camera apps , for example Google Camera / GCam. So I have to enable " Camera 2 api ".
My phone's bootloader is locked and it's not rooted.
Now if I enable developer mode , then enable USB debugging, then I'll connect to my PC and use ADB Shell command to enable Camera 2 api then..
Will I get any OTA updates or not?
Simply I want to get all updates as I am getting now and I want to do use ADB commands without rooting my device or unlocking the bootloader.
Please help me!

HowTo setup Shelter or Island with debloated stock ROM One Ui 3.1 and Android11 ?

Hi everyone,
Iam running my G981B with Android 11 and One UI 3.1.
- I debloated it using the following post Ultimate Debloat S20.
- I reinstalled "com.samsung.android.knox.containercore" and "com.android.managedprovisioning"
When I try to setup Shelter I get the message "Device cannot be setup. If you need assistance please contact..."
When I try to setup Island I get the message "Setup of the work profile not possible. Security rules of your company..."
For Island there is the possibility to do a manual setup: Island Manual Setup
However, if I execute "pm create-user --profileOf 0 --managed Island" I get the most useless response "Error: couldn’t create User".
fw.max_users is set to 10...
Is that a common problem or do I just oversee anything else which I might have debloated and blocks the process right now ?
Thanks for any help !
Okay... obviously tripped knox prevents the device from creating a work profile.
Seriously...
So is there any viable workaround to get something like Shelter or Island running ?
I'll ask to move your thread to Q&A.
I kind of solved my problem by facilitating Samsungs' Dual Messenger functionality.
If dual messenger gets enabled it sets up a separate user profile which is used with a workprofile in order to run multiple messenger app instances.
The beauty is that you can use this to install any app within that profile using adb. So basically the feature is not limited to those few apps you can tick from the settings menu.
Credit goes to @VincentThacker who is describing the procedure here:
Add non-messenger apps to Samsung Dual Messenger?
So the creation of parallel workspaces is blocked in the Security Policy of 8.0, preventing multiple copies of the same app. However, Samsung's Dual Messenger still successfully copies apps it sees as messenger apps, and allows them to run just...

One additional hint from my side:
- If you install aurora through ADB in the work profile all apps you install from this version of aurora automatically get installed on the work profile as well. So no need for installing apks through adb afterwards anymore.

Actually, it doesn't seem to be Knox related: If I setup the phone (Samsung S20) from scratch without FBE encryption (by flashing multidisabler), I can set up Island with the root way and/or by ADB.
If I set up the phone with encryption, Island can't be set up like described here.

Good to know. However having the device unecrypted just to use Island is not an option. Currently Iam quite happy with facilitating Samsungs Dual Messenger functionality for it.
