nokia c2-01 mic solution
If Nokia C2-01 mic is not working then you can slow it easily in a few steps that I am going to post in this post. If mic is not working we can not record our voice and it can not reached to the destination during voice call.During video recording our voice will not be recorded due to this fault.
In above diagram you can see mic tracks these parts are used in mic function and you have to check them with meter if any of them is missing apply jumpers where required.
If parts are burn or damage then you have to replace these parts.
