Nokia Lumia 930 microphone problem

I have some good news. My nokia 930 is currently on windows 10 TP NUMBER 10512 The latest update. I am pleased to report that now I can record videos with sound ( which I couldn't do before on the lumia cam or the windows cam) but only on the windows cam and not the lumia.  Did the test call on skype still unfortunately no speaker phone functionality.  So to summarize areas that still don't work: 

 voice recording on what's app....etc.   voice notes don't work.   Speakerphone doesn't work.  Music searches when device is listening to music still doesn't work unless music is very loud and held close to the microphone near the ear piece then it hears. Indigo an app cortina -like used not to hear me my commands but now it does. Google app still doesn't hear me unless I scream loudly near the earpiece.   Cortina continues to hear me fine. The little microphone on the keyboard hears me fine in all apps. That's all. I am a little pleased now that I can use my phone to record videos with sound but still a lot is missing.

Thank you so very much for updating. Please keep the updates coming and let us know what is happening with your phones. Hopefully we can learn and do something.

They should just replace the handset. They did for me.

Is anything going to be done about this problem. I bought a flagship phone from a reputable provider. O2. I was hoping for a better service. Microsoft need to take charge of situations like this. They have enough money at their disposal. Why not just have an engineer and come up with a solution and fix it.

Has there been any official direct/indirect acknowledgment regarding this problem?

Why not?

Can we amalgamate all the threads regarding this issue?

I am not a social network user, but can't this be taken to Twitter and facebook?

Are they hoping to fix this with Windows 10 mobile (which has no release date yet)?

Earlier I said a possible cause may have been physical damage to my phone, I have now realised by testing on my other 930 that they both have the problem. I am convinced it is software and not hardware. Because Cortana and "Hey, Cortana" work perfectly, even with loud music playing in the background. I don't use Skype and haven't tested that yet.

Update: So I may have posted on another thread. Just to add a bit of info. My phone is being sent for repair today for a smashed screen. I am paying from the via the Microsoft website £125 for this. I have mentioned that there is a Mic problem as well. We shall see what happens.

Update 2: I received my phone back about a week ago. Very quick service. I had it back on the 4th day if I remember correctly. They have repaired the screen and the microphone problem I have been testing it daily to ensure it isn't an app that is causing it to stop working. I have restored my backup, so all my apps are back on. And still the speaker phone mode is functioning. I have successfully used Cortana too. For reference the phone was given back to me with the latest update (8.1 update 1). So I am now convinced that it is indeed a hardware defect. My other phone will be sent, hopefully tomorrow and hopefully in warranty. I will come back with the results. If anyone has any questions please post here. I am receiving email updates of this thread.

Update 3: I have received an email from Anovo regarding my 2nd Lumia. They were unable to repair the Lumia 930 with the microphone/speaker problem and will be replacing it. I don't understand how they fixed the first one and not the second one. On another note I noticed there was a firmware update to the Lumia 930, so I went ahead, as recommended by the Microsoft troubleshooting guide, and updated the firmware on this second Lumia. It didn't solve the problem. It was very difficult to update. It kept failing. Numerous attempts were required. If anyone knows of a contact number then please pass it on, they have given me a non-reply email. I would love to speak to the engineer to fixed my first one.

Update 4: I have emailed Anovo directly. But I haven't been given any reference numbers for the repairs hopefully they are able to locate the cases using just my email address. I have queried why they are replacing the second phone. I am determined to find out what the problem is. They have repaired mine so unless they claim it was a fluke, they better have a satisfactory response.

Update 5: I should receive the replacement of the 2nd 930 today, I missed it yesterday they attempted delivery too early. More importantly Anovo have responded to my email. They've asked for both IMEI numbers. As soon as I received the phone today I will reply to them. I'll post back when I hear something.

Haha, you should charge for this service. :-)
