Microphones swapped – only on Xperia X Compact?
TL;DR
The microphones on my Xperia X Compact appear to have been swapped. Can users with this model or a normal Xperia X help to verify if it's something specific to the Xperia X Compact or if it affects Xperia X as well?
Longer story
About one month ago I flashed my Sony Xperia X Compact with the official Xperia X image, patched with this excellent script created by @g7. Since then, people I speak to on the phone complain about hearing their own voice. Today I checked the microphones with the CSD tool to see if they work, and they seemed to, but then this question inspired me to test the microphones by tapping right on them, and it turned out that the sound is much loader when tapping on the "wrong" microphone. My guess is that the microphones have been swapped in some configuration. It would also explain why people on the other end of a phone call hear themselves – if the top microphone is used instead of the lower one, it would pick up a lot of the sound from the speaker.
How to test
- Start the CSD tool: go to Settings > About Product and tap five times on the version number next to Build
- Go to Individual tests
- Run the below TEST for these four combinations:
- Run test Audio below microphone and tap on the lower microphone
- Run test Audio below microphone but tap on the top microphone
- Run test Audio above microphone and tap on the top microphone
- Run test Audio above microphone but tap on the lower microphone
- TEST
- Start the test (Record)
- Tap a few times with your finger nail right on the microphone
- Stop, play and listen: is the sound loud and clear?
- Compare the sound levels. Do the microphones seem to work as expected, or have they been swapped?
Thank you!

EDIT: It seems like the tests give the same result for both the X and the XC, but that the microphones aren't actually swapped during calls. My echo problems must be caused by something else. The CSD tool should probably be fixed, though.
