Tutorial How to disable Auto Blocker on your Samsung Galaxy phone

Note: I took it directly from Epic Games support page, I just wanted to share it here

Auto Blocker is enabled by default on Samsung Galaxy devices released with One UI 6.1.1. Before you can sideload apps, you need to turn off Auto Blocker by following the steps below:

1. Open Settings
2. Scroll down and tap on Security and privacy
   
   
3. Scroll down and tap on Auto Blocker
   
4. Tap on the toggle to turn off Auto Blocker. The OS will ask for you to authenticate yourself before the feature can be turned off.
   

Once you’ve turned off Auto Blocker, you’ll once again be able to sideload apps
