Use a spudger to gently pry the left black plastic speaker/antenna module off of the frame as pictured. Start by lifting up the right side of the module, then slowly work your way down the module towards the right.

The slight cracking sound you will hear is the sounds of plastic clasps.

We removed other peripherals from the frame so we could move the speaker/antenna module completely out of the way for photographing. You should not have to do this to replace just the fingerprint scanner.
