You're saying the metal piece is from behind the earpiece speaker, yet the phone op showed us in the photo looks intact and absolutely identical to the one in the photo you keep repeatedly posting in this thread.

As a self-proclaimed phone repair hobbyist can you explain how that metal piece that is clearly larger and thicker than the gap between the display and the borders of the phone somehow came from the behind the earpiece and got outside, yet the phone in OP's photo doesn't appear damaged in any way whatsoever.

Again, look at the phone in OP's photo, and the one in your photo. Despite his photo being slightly blurry, you can clearly make out that both earpieces look the same.
