## **Reasons Apple Might Eliminate Face ID from the Foldable iPhone**
### **1. Thickness Limitations**
A major obstacle with foldable devices is their **slim build**. Reports indicate that the foldable iPhone could measure as **thin as 4.5mm when opened**. In comparison, the **iPad Pro M4**, at **5.3mm thick**, just barely accommodates Face ID components. This raises the possibility that the **iPhone Fold might lack the required space for Face ID sensors**.
### **2. Cost and Engineering Complexity**
Incorporating Face ID into a foldable iPhone would necessitate **further engineering** and could hike up the device’s **cost and complexity**. Considering that the **iPhone Fold is already speculated to be priced between $2,000 and $2,500**, Apple might favor a **more economical and simplified** authentication option like Touch ID.
### **3. Location Challenges**
If Apple decides to include Face ID, where should it be positioned? On the **cover screen** or the **inner foldable display**? Having Face ID on the **cover screen** would provide easier unlocking when the device is closed, but users would still require authentication on the **main display** when it’s opened. This might necessitate **two Face ID sensors**, complicating the overall design.
