Apple has started the production process of iPhone 7 series in China. Both Pegatron and Foxconn are reportedly involved in building the iPhone 6 successors, set for September release.

An anonymous tipster apparently sent a screenshot to Mobi Picker showing the monikers of three Apple iPhone 7 variants. The first one is the traditional flagship “iPhone 7” and the second one is the bigger sibling “iPhone 7 Plus,” while the third model is believed to be the “iPhone 7 Pro or iPhone 7 Plus Premium.”

Although there is not much information available about the new Apple iPhone 7 Pro, rumors suggest that this model could feature a dual camera setup. The dual camera setup will include a pair of 12-megapixel lenses on rear of the handset, Phone Arena noted.

One of the lenses will apparently support OIS, whereas the other will be capable of doing 2-3x optical zooming. The zooming technique will be assisted by LinX, an Israeli imaging company bought by Apple.

In general, past rumors pointed out that the upcoming iPhone 7 series will not go through any radical design changes, except for some key configuration upgrades. KGI Securities analyst Ming-Chi Kuo noted recently that the iPhone 6 successor will not come with many “attractive selling points.”

On the other hand, some wild speculations are also making the rounds in the blogosphere. For instance, Apple has been rumored to skip the iPhone 7s series earmarked for 2017. Instead, the tech giant could offer a radically redesigned iPhone 8 for the 10-year anniversary.

Recent reports suggested that 2017’s iPhone 7s will carry an edge-to-edge screen, which will cover the entire frontal portion of the handset. The TouchID fingerprint scanner will apparently be embedded inside the display.

However, readers are advised to take this news with the proverbial pinch of salt as Apple has not confirmed any information so far.
