[SOLUTION] Couldn't install in USB storage or SD problem in Android 4.4
To all KITKAT USERS having problems in installing apps from play store:
If you have tried to install an app and got an error message: COULDN'T INSTALL IN USB STORAGE OR SD CARD PROBLEM,
1. DOWNLOAD and INSTALL SELINUX MODE CHANGER from play store. (Make sure that you have supersu installed and your phone rooted obviously). Grant permission access to SELinux mode changer when supersu prompts you.
2. OPEN SELINUX MODE CHANGER AND CHANGE SELINUX permission to PERMISSIVE.
3. INSTALL THE APP which you wanted for your phone.
N.B. You can change the permission to ENFORCING after installing the app you wanted.
