The Apple iPhone 7 is rumored to be in hot water because of the reported lack of major upgrades. It is even predicted the flagship phone will have less sales.

Fortune reported that the iPhone 7 is expected to be released with few external modifications like no headphone jack and dual camera setup. The lightning connector is rumored to function as a two-way port, which would be used for charging as well as connecting headphones.

Furthermore, rumors suggested that the light sensor of the smartphone will be switched from left to right side with a long receiver. Apple Insider reported that these small changes would not be able to tempt iPhone 5, iPhone 5S, iPhone 6 and iPhone 6S users to switch to iPhone 7 device. As a result, the sales figure for the company is expected to go down, according to many research analysts.

Also, the iPhone 7 will not consist of a home-screen button. Leaked images showed that the smartphone would be launched with a new color option, Space Black, which would be similar to that of the company's smartwatch, along with other regular Apple colors like silver, gold, rose gold, and space gray. However, 9 to 5 Mac reported that these subtle changes would not be able to increase the sales this year.

Meanwhile, there are rumors that the iPhone 7 device would feature a 4.7-inch screen with three variants i.e. iPhone 7, iPhone 7 Plus and iPhone 7 Pro. The smartphone is also expected to feature an upgraded A10 processor with 256 GB storage capacity.

On the other hand, there some predictions that Apple's iPhone 8 would be the one to steal the show next year. Mac Rumors reported that iPhone 8 will undergo major design haul, highlighting an all glass casing with an edgeless display.
