Sound up & down when recording video
I noticed that the sound volume of any recorded video in my iPhone 6s starts low and then increases/ decreases with no obvious reason.
The sound result is like switching microphones front/rear, however I am not an expert and this is just a wild guess to describe how it feels like.
When I play the video in my computer, the sound issue is still there, so it should be a microphone hardware or software issue?
I haven't exposed the phone in any humidity sources nor having dropped it.
For the record I have tried to tackle the above issue by:
- testing the iPhone's stock camera app vs. other video recording apps and the issue persists.
- restoring and set up as new
- resetting options etc
with no good results.
Is this a good question?
