Martin Hajek has even sketched a design for the new smartphone in which he drew the home button on the screen itself, reducing the dead space around the phone, reports ComputerBild. This is actually a nifty idea and can be a great addition to the phone, if the makers are really interested about the suggestion. Apart from that, Hajek also included dual lenses in the concept design. Removing the camera hump from the back of iPhone 6 as well as iPhone 6 Plus, he made the phone a bit thicker than the existing model, may be he wanted the phone to have a bigger battery for better performance. The design has also removed the antenna stripes from the phone. While the concept design for iPhone 7 has created stir in the media, the company is expected to launch its iPhone 6s model with better functionality sometimes this fall. Yet, so far there is no update on the design modifications.
