Apple is maintaining utmost secrecy on its upcoming flagship smartphone dubbed as the iPhone 7 and it may not reveal even a bit till it is released, but that won't stop leaks. Several details of the device have been leaked over the last few weeks, and a plastic case of the purported next-generation handset has provided more insight into its design.

Popular leakster Steve Hemmerstoffer @OnLeaks has posted a case of Apple's iPhone 7 on his Twitter page. It is difficult to tell what the upcoming flagship device will look like from the case, but the cut out for ports do give a good idea of a possible design.

According to reports, the iPhone 7 will have a flat metal look sans headphone jack and measure between 6.0 and 6.5 mm in thickness compared to the 7.1 mm seen in the iPhone 6s. The leaked iPhone 7 case has also indicated that the lightning connector will replace the 3.5mm headphone jack.

It was also reported that Apple's iconic Home button will not be discarded in the upcoming smartphone, but the case in no way can throw light on that.

Interestingly, Apple Insider has reported quoting Japanese blog Mac Otakara that the iPhone 7 share the same height and width with its predecessor, iPhone 6s, which means it will have a dimension of 138.3 x 67.1 x 7.1 mm.

According to reports, the iPhone 7 will sport a 4.7-inch LCD display, powered by an A10 chip, come packed with a 2GB/3GB RAM, and house a 10 MP camera or a two-lens DSLR-style camera with optical image stabilisation (OIS).

Apple hasn't revealed the release date of the iPhone 7, but it is expected to happen in the third quarter of this year. It is expected to be unveiled in September, as its predecessor, the iPhone 6s, will complete a year cycle in the market by that time.
