Chosen Solution
My mom had this problem with here phone for quite some time now that here voice is really muffle when making a call. However when switching to speaker the voice gets much clearer. So I did a bit of googling and it seems like the noise cancelling mic on the top is the problem. Though I haven’t found a solution for it yet. It has no warranty so that’s not an option. As far as I can see the noise cancelling mic is part of the motherboard, so in case of a hardware defect the whole thing would have to get changed, right? In case it’s a software problem, how would one go about fixing it? Thanks in advance!
check for dust/lint in the microphone hole on the bottom edge of the phone, as far as i know when switching to loudspeaker it changes to the mic thats used for videos etc
