Will the iPhone 17 have an under-display camera?

The iPhone 17 may not use a true under-screen camera, but it is expected to introduce hidden front-facing camera technology. 1. Apple is studying hidden camera solutions, including special pixel arrangements and miniature modules, making the camera invisible when not in use; 2. Although the notch screen is mature at present, Apple hopes to increase the screen-to-body ratio while ensuring FaceID and selfie quality; 3. The real under-screen camera still faces challenges such as imaging quality and screen aging, and Apple is unwilling to sacrifice experience for design changes; 4. Users are more concerned about functional performance than whether the notch exists. If the hidden camera does not affect the experience, removing the notch will become a natural result; 5. Overall, the iPhone 17 may adopt a compromise solution, integrating the camera module below the screen and achieving visual hiddenness.
