Thanks for your reply. The microphone is broken. I already unscrewed the Phone all the way and saw that the microphone is loose under all the protecting parts. Does this make sense? I cant describe any better since my english is very limited in technical topics.
If you read this post you may be able to contact the author for help in repairing the mic. There are details elsewhere on the connecting strips that need checking and the flexibility of the board that allows the mic to seperate.
Up to where exactly did you unscrew the phone, and what is loose? The bottom module? The microphone inside the module?
If you need, you can also describe your problem in German. There are several German-speaking people on the forum.
Wenn du es brauchst, kannst du dein Problem auch auf Deutsch beschreiben. Auf dem Forum sind viele deutschsprachigen Menschen.
Though I am not dismissing that it is unrepairable by you or anyone you know from what I have read the module has to be broken down to get to the back of the area where the mic is fitted. Once that has been achieved it may be possible to effect a repair. However the skills required are beyond most people’s desire to learn.
No, I took this picture The red marking shows the wireing on the printed circuit board. The yellow mark is where a solder joint is missing. Also this PCB is broken. The copper is covered with solder tin why it looks silver.
And as this technology of PCB is called SMT (surface mount technology) there is no related wireing underneath. Probably this is a multi layer PCB, which means that there is also wireing between the top and the bottom side of the PCB.
