need help! what is wrong with my mic? broken when on-ear call, not during speaker
no known damages at all. yes rooted, i have flashed multiple roms, so i dont think its software, i think it's a hardware problem so i'm asking if there's a way around it. Yes I have sound enhancement disabled and yes I have cleaned it with a brush
problem - when making a call on-ear, the mic doesn't work. when i put it in speaker the mic works again.
therefore i ask, does the phone using a different mic between on-ear and speaker? if the answer is yes, how can i switch which mic it uses? if the answer is no, what is wrong with the phone?
