Liquid damage diagnostics: which part of the phone is in this pic?
I've sent my iPhone 7 Jet black 128 GB to Apple in order to have assistance since the phone speaker stopped working properly (the one you bring to your ear, it still works but sound appears softened).
In their diagnostics they say the phone has received liquid damage and they have provided a picture to 'prove it' (wasn't it supposed to be proved thanks to the red indicators?).
I can't figure out which part of the phone this is, I've watched several teardowns but still couldn't understand.
Can you please help me out here? Thank you
Here's the pic they sent me:
Is this a good question?
