If accurate, that would put the "iPhone 7" in line with Apple's current iPod touch and iPad Air 2, both of which are just 6.1 millimeters thick. In contrast, the current iPhone 6 is 6.9 millimeters thick, and new 7000 series aluminum on the "iPhone 6s" are expected to make that device just over 7 millimeters thick.
Kuo says he believes Apple does want to switch to glass-to-glass, especially if the company goes to a higher resolution; however, the company's drive for thinner devices might delay that a few years.
"Apple and its suppliers have invested heavily in iPhone Force Touch in 2015 and we believe 2016 new models will stick with a similar Force Touch structure as used in 2015," said Kuo.
Apple is set to unveil its next generation 'iPhone 6s' on September 9th at the Bill Graham Civic Auditorium. Please follow iClarified on Twitter, Facebook, Google+, or RSS for updates.
