Stock Android Hack - Android Q&A, Help & Troubleshooting

Purchased a Samsung which have preinstalled a stock version of Android 9.
I want to know if someone can decompile the stock firmware and embed a malware or smth that can send anonymously details about the way phone is being used. (i suspect that the people that work at that carrier did that).
Also, do you recommend any antivirus or some software that can detect (and what should we look for) any suspicious activity that run on my phone.
One way is to install a custom rom but first i want to find out if the phone is as i suspect
Please advice.

Well, at least you can disable bloat app now, without root, via PC with debloater.
About apps that are suspected as bloat, you can see in universal debloat scripts that require root. Like this or this.

how do i know the apps that are bloating my phone? almost all apps comes with a form of advertising either a pop-up banner or the advertising that is embeded in the platform (such as youtube, that you can get rid of if you pay, i guess).

To remove bloatware from Samsung smartphones, you might use a paid 3rd-party app called Package Disabler Pro from the Google Play Store which can uninstall bloatware in few taps. It’s a pretty straight-forward process without dangling with a PC and that’s why it's the recommended method. However, the app uses Device Administrator privilege to uninstall apps, which is very sensitive permission to grant. If you are comfortable with granting the permission, you can go ahead.
Download Package Disabler Pro from the Google Play Store and install it.

Now, simply select the apps by tapping on the checkbox and they will be disabled. To confirm the changes, just tap on the Disabled section below to see all the disabled apps. Similarly, you can uncheck the boxes to enable them.

Really ?!
Requiment says: Root OR KitKat+ (4.4+). User has Android 9. If not, you can disable almost any app from /system manualy, without PC nor root.
BTW, thread title says: V3.90 Debloater(Lets remove all that carrier bloat !! Root not required..)

You are right. Most of app uses Google Ad service. Maybe you need ad-blocker for non-root phone like Blokada. Some kind of VPN-filter, since can not write hosts file.
About ad-ware app look at this list of Samsung apps.

Bloatware are the apps what OEM/Carrier get paid for to install, bloatware typically is installed in /system or /system-priv: hence the term bloatware. Removing an app ( means completely remove it from storage medium without leaving a trace ) that is located in /system or /system-priv requires ROOT privileges. Point.

Agreed! Non-rooted phone can just disable them. Rooted phone can uninstalled them.
I had just suggest to user to disable apps (and services), until he decide to root phone or install custom recovery and delete system bloatware.
