Can you take all the parts of the iPhone 6 and put them into an iPhone 6s housing? The reason i ask is because the aluminium is stronger on the 6s and it won’t bend like how it does in the iPhone 6 housing.
Mustafa Khalid at minimum all the mounting screws etc. are in a different position. The aluminium case has a different layout. No, it wont fit as is.
