Microphone does not work, everything fits Other. In sum, of course NO GO!

My old note was hardly invite. Battery replacement did not help because I found this thing. Many write to other providers, the part would not original and there were problems with the reception. That's why I hesitated with buying long.
The exchange was quite easy with Youtube instructions.
In fact, the charge of the music was now perfect. The next morning I had full battery, reception was as usual, but my opponent could not hear me!
If I switch to speakerphone, it's not over micro.
Then have the part again expanded and the old board back inside. Micro goes. Old out again, new clean, micro is not again. So it is but in the new part.
The component of the micro looks visually somewhat different than the originals.
I return now and buy me a new board.
Basically, this is a very good thing, I'm holding a faulty catch.
