I am a Nokia/WP fan who has now 3 WP including this 930 model. (w/ the other 2: 925 and 6xx)
At the beginning, I am not so unhappy and take it too seriously, thinking this could be a SW defect that MS or Nokia should have some fix, or could exist some walk-around.
BUT, after Google for a long time and reading all those posts - I feel so angry and frustrated that MS/Nokia CAN leave such an issue un-fixed for more than one year! I brought my 930 three month ago, and the microphone problem probably started 1-2 month after the purchase, where I now and then receive complain form the other end if using speaker to talk (which I seldom did actually).
I am so SHOCKED 2 tech GIANTS can leave a really big mul-function for years and continue to sell it as a FLAGSHIP model - WHAT AN ATTITUDE!!!!!!
I am start to wondering where is the QAs and what's product release/maint. program looks like.
Not exaggerate, if a user trying to use this phone on speaker during driving, if him/her attention been distracted because the other end continue ask repeating etc. could be quite dangerous...
"Hey Cortana, can you help tell MS/Nokia to fix this mic issue, kindly??" ... obviously she cannot hear.
