GoKawiilSamsung's Auto Blocker security feature ships on by default from One UI 6.1.1
Samsung Galaxy phones running One UI 6.1.1 or later come with Auto Blocker enabled automatically, a feature that filters risky apps, USB commands and messages in the background. It blocks sideloaded apps and installs from outside the Google Play Store or Samsung Galaxy Store unless users manually adjust the setting. Epic Games previously sued Samsung, arguing the feature made installing third-party apps like its own store unnecessarily difficult.
