IT Home reported on July 24 that the technology media Android Authority published a blog post yesterday (July 23),It means that new Samsung Galaxy series phones and tablets pre-installed with One UI 6.1.1 system will prevent users from sideloading applications from unauthorized sources by default.


Permissions Overview

IT Home briefly introduces the relevant information about Android permissions as follows:

INSTALL_PACKAGES

Technically, Android already blocks sideloading by default at the OS level.INSTALL_PACKAGES The permission (to silently install new apps without prompting the user) is only granted to the app store pre-installed on the phone (such as the Play Store, or the manufacturer's app store), and is automatically granted to the app that requests it.


REQUEST_INSTALL_PACKAGES

Most third-party app stores use REQUEST_INSTALL_PACKAGES Permissions require explicit authorization from the user during the application installation process. Every time an application with this permission tries to install a new application, the Android system will prompt the user.

Auto Blocker function

Samsung debuted the Auto Blocker feature in One UI 6.0, which completely blocks the installation of unauthorized apps even if the app has been granted the REQUEST_INSTALL_PACKAGES permission.

After enabling the Auto Blocker feature on Samsung phones,Users can only install and update apps through the Google Play Store and Samsung Galaxy App Store.

In Samsung One UI 6.0 system,Auto Blocker is an optional feature and is not enabled by default, users can open the Settings app and manually enable "Auto Blocker" in "Security & Privacy".

Samsung Galaxy Z Fold6 and Galaxy Z Flip6 are pre-installed with One UI 6.1.1 update.The Auto Blocker feature has been enabled by default, but users can turn off this option and continue to sideload apps.
