KGI: ‘Increasing likelihood’ iPhone 8 will feature glass front and back, stainless steel metal for premium models
Reliable analyst Ming-Chi Kuo of KGI Securities has released a new report further forecasting that the 2017 iPhone will likely adopt and glass front and back design like the iPhone 4 and iPhone 4s.
Context & Ripple Effects
Ming-Chi Kuo has been building this call all year: his March report already had Apple planning a 2017 iPhone with a curved glass case, 5.8-inch AMOLED display, and wireless charging. Today's update raises the confidence level and adds a material split — glass front and back echoing the iPhone 4/4s, with stainless steel reserved for premium models.
The detail matters because a glass back is what makes the wireless charging in that same roadmap physically possible, and because it marks the tenth anniversary redesign as a materials story, not just a screen story. A decade later, sourcing still points to Apple executing a glass-centric Pro overhaul in 2027 — this 2016 note is where that arc starts.
First-order effects
- Apple's 2017 lineup splits by material rather than just size: stainless steel frames signal a visibly distinct premium tier above aluminum models, giving the top SKU a design justification for its price.
- Casing suppliers pivot ahead of the launch — glass cover and stainless steel fabrication capacity gets pulled forward while aluminum unibody orders face a smaller share of the premium mix.
Second-order effects
- Wireless charging moves from rumor to near-certainty once the metal-back constraint disappears, pulling the accessory ecosystem toward charging pads and pressuring Android vendors already shipping glass-backed phones to defend that differentiator.
- A glass-and-steel chassis raises repair and durability stakes, which flows into AppleCare pricing and third-party repair economics for the flagship tier.
Third-order effects
- If the pattern holds, the glass front becomes the enabler for the next interface shift — consistent with Kuo's later call that all 2018 iPhones would drop Touch ID for Face ID, since a full-glass front removes the home button the fingerprint sensor lived in.
- Materials become the recurring reset lever for iPhone differentiation: the 2027 glass-centric Pro reports suggest Apple treats a return-to-glass cycle as a repeatable playbook rather than a one-off anniversary design.
The trend: iPhone industrial design is entering a glass-led cycle — announced here for the 2017 tenth-anniversary model and still driving the Pro line's roadmap a decade later — where enclosure materials, not just internals, carry the premium pitch.
