Microphone not working during calls

[ItzBradleey123]

I recently got mud in my phone. The charging port and speaker. The speaker is cleared out as well as the charging port. But when I call someone they can't hear me, but when I use speakerphone they can clearly. It also doesn't work for any other voice recognition such as Google or videos. I don't wanna factory reset my phone as I'll lose my data on it and if I move it to my sd card it'll mess up all my photos and videos. Help please

Hi @ItzBradleey123, sorry to hear about this.

I would recommend that you start with the inbuilt test in your device called Diagnostics, in here you test certain things, such as the microphone. The test can be found in Settings > About phone > Diagnostics > Test > Microphone. Is the microphone working in this test?

Let me know how it goes!

Yeah I've tried that doesn't work. Its the same for calls and recording audio. And voice searches. 

I can deal without it not working it's more of an annoyance. I would prefer it fixed if I could

Hi again and sorry to hear that it does not work in the test either.

It may be related to hardware as the microphone doesn't work at all, but I still recommend that you perform a software repair using Xperia Companion, just to make sure that this is not related to the software in your device as it will be reinstalled when performing the repair. In the same process all data stored on the internal storage will be deleted, so it is important that you create a backup using Xperia Companion before starting with the repair procedure.

Is there is no change after the repair has been finished and you have tried the microphone, the device will need to be examined by a trained technician at an authorized service centre. Your Local support team will assist you further with this and answer any questions that you may have regarding warranty, local service routines and so forth.

Keep me posted!

Hi Jonas; 

I am having the exact same issue but due different causes (my phone drop off from bed). Mic not working unless I used “loudspeaker”. As a note, I have tried diagnostic tool, a software repair by Xperia companion and all that good stuff, to no avail.

I did some research and came to conclusion that mic was damaged during the fall. I myself am experienced in electronics and basic phone parts replacement; I decided to give it a try (no tech support from Sony anywhere near).  I opened the phone and when removed the plastic part where the loud speaker is, on top the mic flexor, I immediately saw that the microphone plate/cover (a small rectangular metal plate) was not completely attached/pasted to the charger/mic flexor circuit. Furthermore, when touched it dropped apart, including a very tiny metal component inside the internals of the microphone. I re assembled the phone back, and after that, not even the “loudspeaker” worked anymore (the loudspeaker does work, I mean the microphone function while using loudspeaker function), what I assumed was due the microphone disassembling completely after opening.

Therefore, I ordered a replacement flexor; it came in yesterday so today I replaced it.

Well, I have the same result, the phone microphone does not work, not normal or loud speaking mode. It is just like with the broken microphone flex. What I did notice different this time is that if I “use” the mic to try to catch very loud noise/sounds, and then playing it back, I am able to ear the loudest sounds if I put the volume all the way up and get the phone as close as I can to my ears. This does happen again if, by using some app (like whatsapp audio messaging) to record something meanwhile I’m playing a song with the phone, the sound is able to be recorded, again, very low volume, but louder than any external sound.

Summary: I am lost. The new flexor replacement did not solve the issue, but it seems that somehow the mic is “almost” muted, as it records only the loudest sounds. In practice, during a phone call for example, this useless.

Any advice? Running or of alternatives, either the new flexor is also damaged, or…worst, there is something bad with the motherboard.

Any bit of help is appreciated. Regards.

Hi @ECastaneda, sorry to hear about this and I apologize for the late reply. I have been out office due to vacation.

As we only provide aftermarket support and all the repairs are handled by our authorized service centres, it's hard for me to say what is exactly what is wrong with your device and I would recommend that you get in touch with your Local support team and they will assist you further with arranging a repair.

Keep me posted!
