Are you using the 25w Samsung cable and adapter?
Your phone does support fast charging however the correct charge needs to be used.

[IntolerableGenius]

You need to be using a 25w charger to enable the fast chare capability for your device.

You can try any other electronics store for a generic 25w charger. The adapter without the cable is R499.
