Materials: TouchID ring & iSight / Flash LED glass
Can you confirm what material is being used for the metal ring in the Touch ID?
Why is the metal ring necessary to the unit?
Can you dissect how the antennas are attached to the unibody aluminum and glass backs? I feel like you stopped at step 20 for "fixing it" purposes, but fancy us who just wanna see how Apple makes the phone!
What material is being used for the LED flash glass and iSight camera protector glass? How are they attached? drop in? or glue?
