An alleged photo of an iPhone 5 production line from China appears to confirm, among other things, that the iPhone’s home button will indeed undergo a major change when the iPhone 5 is released this fall. The leaked photo, which came to us from a user on Weibo, China’s version of Twitter, seems to show a row of iPhone screens going through quality testing and assembly in a manufacturing plant in Taiwan. At the bottom of each iPhone screen is a large rectangular cutout for the iPhone’s home button—a major departure from the iPhone 4’s round home button.
Rumors of a change to the iPhone 5’s home button first cropped up in a report by This Is My Next, who claimed the home button area would be “enlarged, but not scrapped altogether.” The mock-up of their iPhone 5 home button can be seen below.
Recent leaked iPhone 5 case diagrams also hinted at a new button:
The idea of the home button becoming a touch-sensitive strip, or in our opinion, gaining touch capabilities in addition to continuing to function as a tactile button, was later added via speculation by rumor sites.
The production-line photo also appears to show that the iPhone’s screen size will remain at 3.7 inches, although it’s difficult to 100% confirm that from the photo. The size of the screen’s bezel appears to be about the same as the iPhone 4’s, indicating the size will remain the same.
This Is My Next’s report from April also had this interesting tidbit:
Our source says the company is doing very “interesting things” with bonded glass technology, and has been exploring designs where the earpiece and sensors are somehow behind the screen itself.
Judging from the production-line photo, cutouts for the earpiece and sensors do appear to be missing, although, again, it’s difficult to confirm this from the photos.
