I beg before you please tell its iphone 4s?

Friends i have australian iphone 4s, it can't be repaired by apple care in india (my country) and its also out of warranty, when i record video the voices being recorded are bit low, i'm not using any case etc,
please tell if i replace its top mic from local mobile repair shop, will its sound be louder?
sorry for bad english

Only way to tell is to go into the store yourself and ask them.

Only if the mic is stronger.
