This is on an original SE 64GB. When my daughter shoots videos, sometimes the audio is perfect, even for a 15 minute video. Other times there is a warble to the audio. Almost like the person in the video is underwater, though not that severe.
It’s not a speaker issue, if she sends the video to my iPhone and I watch it with ear buds I hear it as well.
She bought the lightning connector based external mic Apple sells for $80. No difference. Sometimes good, sometimes bad.
This would seem to mean it’s an issue with her phone internally.
I’m going to take it to an Apple
store for diagnostics but before I go I was hoping to hear if others have had the same thing. If so please state which model iPhone you have and whether there was resolution.
