So does anyone know which mics are used to pick up video audio? I was hearing some random scratching sounds in a video I recorded and I wonder if any of the mics on the back (where my fingers were) are used for video?
This right bottom mic is the only one used to record audio during a video. If you are used to sitting your finger there you will hear that scratchy sound when your finger moves and you'll muffle the audio.
Re: [SOLVED] Scratching sound during video recording
This is also important since a lot of cheap cases don't have the holes needed for the 3 extra mics (the 3rd one is to the bottom right of the camera lens). For example I ordered a $2 tpu case from ebay for my 2014 x and it doesn't have *any* of the rear mics uncovered! Not only would this impact video recording it would also impact the noise cancellation and voice recognition.
