Question [Q] Guest Mode and Sharing

Guest Mode on the LG G2 is a great feature.

But I found that if from the guest mode you shared something (From the gallery, browser or any other app supporting sharing), the user have the ability to choose any other apps installed on the phone (even if these app are not shared). And once the app is open, they can browse to it.

Have somebody found a way to block sharing from the guest mode?

Thanks for your help,
