I inserted the pin in the left bottom microphone
this morning I've been quite dumb: trying to insert the sim into the newly arrived mate 20 pro, I inserted the pin into the left bottom hole instead of into the correct one on the sim slide...
Does anybody know what are those two holes? Microphones? May I have broke something? For example the waterproof integrity?
I installed a testing app and tried to register covering alternatively the two holes and it seems that the phone correctly register my voice..
There is a third hole on the top, is that another microphone?
I'm not sure I damaged something: when I phone, on the other side my voice is well received, besides I re-tried to insert (extremely slowly and carefully) the pin inside both the bottom holes and it find something hard at the same depth, so it seems that nothing has been perforated.... but, I really would like to know where to find technical schematics or tear down videos to see how these two microphones are mounted and which is their function.
If I try to register something with the recorder app and I tap alternatively on the left hole and the right hole, only the second tap is registered... so two are the cases:
1) I destroyed the left microphone, but the right one is sufficient for any application to work correctly
2) Nothing is destroyed, but the left hole is something else or the microphone inside is used for other purposes (noise reduction?)
Does anybody know where to find the phone schematics?
Thank you for any answer
Is this a good question?
