Apple is still a long way from announcing the all-new iPhone 7, but rumours are continuously flowing in even with the smallest details. While some analysts are predicting Apple's iPhone sales to decline in 2016 due to lack of new features, rumours suggest the iPhone 7 would bring some notable changes such as dust and waterproof design and a Force Touch home button.

Apple may be holding back its innovation card for iPhone to be shown in 2018 with the iPhone 8, which is expected to bring a major redesign and incremental upgrades, leaked specifications of the iPhone 7 suggest this year's flagship won't be a complete turn off. According to GSMArena, there have been prototypes of iPhone 7 with touch-sensitive capacitive home button with 3D Touch feature that will sense the pressure applied to carry out different actions.

The source, originating from China as reported by DigiTimes, suggests the iPhone 7 has completed third round of testing to get dust and waterproof certification. Another report from 9to5Mac, citing a Chinese website Storm, said that a digitally synthetic touch-sensitive home button would allow Apple to seal the exterior casing of the iPhone to prevent water from entering the device and causing any damage.

Rumour build-ups regarding the iPhone 7 have pointed out several details, one of which is the controversial removal of the 3.5mm headphone jack. The Cupertino-based tech titan is said to include wireless Earpods and a smart connector so users can attach headphones to the Lightning port. The camera of the iPhone 7 is also expected to receive a major upgrade.

Rumours suggest the iPhone 7 Plus variant to have a dual-camera setup, according to KGI analyst Ming-Chi Kuo. There was no mention of a similar set up in the 4.7-inch variant this year. The antenna lines behind the iPhone are also expected to be pushed alongside the sides, giving a plain rear design.

Apple is considering a major design revamp in 2018. The iPhone 8, which would replace the 7s model next year, is expected to come with all-glass casing instead of aluminium chassis as in the current iPhone models. Kuo also believes the iPhone 8 would feature AMOLED display.
