Go to Settings >> Security >> Device Administration >> Turn on “Unknown Sources”.
Download and open APK file.
Click Install >> When displayed “Blocked by Play Protect” >> Click Details “v” >>”Install anyway”.
After the installation process, you will have Lucky Patcher icon on the home screen, tap on the icon and start using it!
Note: Lucky Patcher is not available on Google Play Store which is why Android security by default will prompt it as a harmful app during installation. Simply ignore the warning because it is completely safe to use. Use “ES File Explorer” or any similar app to unzip the .APK file.
