Unauthorized Software Issue. !!

[KhuzaimaRajput]

I'm facing unauthorized software issue while setting up my secure folder. Is there any solution? I want to use secure folder but whenever I try to setup the pop-up appears saying "Unauthorized Software" Try again. 

What should I do ?

Is your phone officially approved or patched? and confirmation regarding any software modifications, including rooting.

Your phone's boatloader must be unlocked, or its patched. Thats why your getting this error.
