Both the Samsung Galaxy S5 and iPhone 5s brought fingerprint scanning to the home button. And both did it fairly crudely, with a flimsy cable in the line of fire when opening the device.

The iPhone 6 and 6 Plus saw Apple rerouting this cable into the display assembly, to better protect it.

Samsung decided to simply detach the home button from the display assembly, so that its cable now routes down into the interior.

This eases the opening procedure a bit, but the capacitative touch button cables are still obnoxiously delicate and require painstaking precision to free.
