Switched to iPhone 6+ some months ago already because chance of a fix from microsoft is zero.
Stupid thing tho is that the lower microphone is working fine on normal calls and even on video recording only on speakermode no work.
So what is wrong on speakermode? when used skype i switched continuously from speakermode to telephone because in telephone the microphone works fine.
I cannot believe that the microphone is broken on speakermode and same mic is working on telephone mode?
My mic worked fine straight out the box and only after going to Denim update start troubling.
Also you can hear the mic switching off, you hear 'bloob' when going to speakermode.
i am 100% convinced this is a wrong assignment for the lower microphone on speakermode and i think it has to do with firmware from phone together with sofware.
I tried windows 10 version 10666 but still no luck, will continue use the iPhone where everything always works.
I will never ever spend money anymore on anything windows because all my Apple products work, never fail or break or problem, nothing and this for years and years already. No wonder windows phone is not a succes
