Leaked pictures of what allegedly is the home button for the iPhone 5S discloses a few similarities to the same part of the iPhone 5 although the connectors and the circuitry are both reportedly different than what is seen inside the present Apple Smartphone.
The serial numbers are close enough to make this seem credible. Also leaked is a picture of a vibration unit for the iPhone 5S. No serial numbers or identity seemed with the photos for this part. While one of several speculations about the iPhone 5S was that it would offer a fingerprint scanner in the home button, the leak looks to put the kibosh on that rumor thinking about how similar the button considered for the Apple iPhone 5S is opposed to the one used on the iPhone 5.
However, leaked pictures allegedly of the loudspeaker module for the iPhone 5S and iPhone 6 from back in January, recommended that the next-generation iPhone would be known as the Apple iPhone 6 with a low-cost model called the iPhone 5S. Now, it is still feasible that a home button along with fingerprint scanning features would show up in parts for the iPhone 6.
