Apple is said to be working on a folding iPhone. Now, an indepth report from an industry heavyweight gives details on what it could be like.

Apple could ship its first foldable smartphone next year, according to Ming-Chi Kuo, an analyst for TF International Securities who closely monitors the company’s supply chain. Apple didn’t immediately respond to a request for comment early on Thursday.

Kuo also says the 1st gen foldable could give Face ID the boot because of the required thickness and internal space constraints (Apple's apparently shooting to keep the profile at 4.5mm to 4.8mm when unfolded, and 9-9.5mm when folded), and will instead bring back Touch ID as a side button.
