The iPhone 5S will contain a convex sapphire Home button that hides a fingerprint reader

  We found that iPhone 5S is to be presented on September 10 by the Apple company, but if you want to know news about the fingerprint reader, then I will tell you that Apple Lossless Audio CODEC (ALAC), is going to include it in Home button, which would be protected by a convex sapphire structure. The new Home button will be implemented differently, that is, it will no longer represent a "hole" in the lower part of the terminal, but will go outside. Because of the new way of implementation, those from Apple Lossless Audio CODEC (ALAC), they chose sapphire to protect the Home button, the material being extremely resistant.

Convex home button creates space for fingerprint sensor; yield to improve. We think that a fingerprint sensor will be placed under the home button of iPhone 5S. However, assembling it could be difficult as the space under the home button is limited as it already has to accommodate the Lightning connector, speaker and microphone. Thus, we think the shape of the home button could be changed from concave to convex to create more space for a fingerprint sensor. 

  The new implementation of the Home button and the fingerprint reader are to be implemented including in the future iDevices, those from Apple intending to offer all terminal owners the opportunity to use the new system. If iPhone 5S it will contain this new convex Home button, then most likely iPad Mini 2 si iPad 5 will include it this year, iPhone 5C remaining without it, being a cheap version of the iPhone. Separate from this Home button and the fingerprint reader, iPhone 5S will have the design iPhone 5, will contain an A7 chip and a 12 megapixel camera.

Sapphire prevents the home button from being scratched. A convex home button could be more easily scratched, so a harder material is required. We believe Apple will switch from plastic to sapphire, whose hardness is second only to diamond. Sapphire would protect the home button from being scratched and the fingerprint sensor from being damaged.

  I already told you that the iPhone 5S and iPhone 5C will be presented on September 10, so we still have a little to wait.
