    We can see that the box to the right of this option is currently green, with a white check mark inside of it. This means that right now, this option is turned on. We are currently allowing the installation of applications from unknown sources. This can be slightly dangerous, if we do not know the source of the application then we do not know who has made it and we have no guarantees about it. We will not know if it contains virus' or is protected, or what it is actually going to do to our phone. It is a lot safer to install applications from sources that we know and trust.

    If we want to turn this option off, simply press down on the green box until the checkmark is gone. When the option is turned off this box with be transparent, with a gray outline. This now has deactivated this option, any application from an unknown source will not be allowed to be installed on our HTC One M8.
