I recently disassembled my old Nexus 5 just for the fun of it. I came across a part and I am unable to figure out what it is (I attached two picures - The part I mean is the small hole next to the headphone jack). I am probably just not seeing the obvious but could anybody help me out? A friend of mine said it is an IR blaster but I checked and the Nexus 5 does not have IR. [Sorry, forgot the pictures]
Hi, I’m not sure and I wouldn’t know the part number, but to me it looks like it might be what is known as a tertiary or noise cancelling microphone if it is connected to the systemboard. I cannot make it out too well. Given that in the picture there seems to be a hole leading to outside the case in front of the component. Here is a link to what I am talking about. http://www.techradar.com/news/phone-and-…
