The front of a car is where the headlights are located, moving forward. It could be argued that, when backing the car, the front is the back, at that time. But, you are right - crappy analogy. Grill location doesn't necessarily tell you everything, either. A rear-engined (or electric) car may not have any front grill at all.
The seats face forward (well, except for that beater that my older brother had when I was a kid. The seats moved around a bit too much
)
The point of my quick response was this...
A CAR front/back are named from the perspective of 1.) someone on the OUTSIDE looking in, and to your point which I hastily left off, 2.) the direction the car normally travels.
A CAR front/back is **NOT** named based on the DRIVER's perspective.
The same applies to planes, trains, buggies, horses, and even humans!
THUS, being of that mindset, I would have thought that the "front" of my iPhone was on the solid/non-glass side where the camera resides...
It was a legitimate question, but as often the case, there almost always has to be a snarky response from someone from the peanut gallery here at MacRumors... (Not you, Delta...)
The screen is the front of the phone, where you see and control everything. The camera that you would use for selfies is front-facing. The more capable camera(s) on the back are, well, rear-facing.
Got it.
I think you have to go back to the iPhone 4 before there are fewer than 3 microphones. I'm pretty sure that all of the 3 microphones are used with some mixture when recording audio.
I ask, because whatever happened to my iPhone 6S Plus, it was severe enough that it trashed 3 weeks worth of interviews...
I thought the certified repair place said it was the "bottom" microphone, and so I am inquiring in my OP as to how many mics thrre are, and their significance because I am trying to do a post-mortem of sorts...
Hope to hit the field tomorrow and start interviewing people, and this time will be relying primarily on my shotgun mic and wirless lav setup, but still am trying to better understand the workings of iPhone mics and also tryingt o set my expectations of how things should work.
(One thing I know that I need to be more aware of is that when I "ride bareback" and use my iRing, I probably need to stop cupping the phone in my right hand as my palm often covers up the botom microphone - althoug that wasn't the issue with my iPhone 6S Plus...)
