iPhone problems recording sound during videos, possible solution.

So I had a problem with my iPhone SE Gen 3, iOS 18, it developed an issue recording sound when recording a video, approx March this year.

To be clear, I have a basic level of engineering so, I tested the phone simply recording sound, no issues, also phone calls were made without issue, as were video calls so the issue was absolutely NOT a hardware issue, it was undeniably software. This issue occurs both with Apple software and 3rd party software, but as I said, the evidence indicates it is 100% a software NOT hardware issue.

This issue would occur whereby the sound would drift in an out when recording videos over a regular period roughly every 20 seconds, I posted a question and a mod decided to close it when it had zero replies, something I have noticed seems to happen on a lot of posts on this issue, perhaps someone would like to explain that?

Anyway, fast forward to today. I was giving it some thought and thought maybe, try uninstalling then reinstalling the Apple propriety Camera app as a test. Before uninstalling I went to the app store to ensure it was available there.

Now bear in mind I still had the Camera app installed, yet despite this, when I did find it in the app store it indicated I needed to download it?!

As such I did re-download it, I checked my screens for a new Camera icon for the app but found only the original. Since then it seems (touch wood) that sound recording has been restored to my phone during videos.

Let me be clear, this was NOT an update, this was absolutely NOT listed as requiring update, this was a cloud with an arrow to indicate it was a download, like an app that you I had uninstalled and had the option to restore to my phone.

While I won't say this will work for everyone there may be some, like myself who it does help.

In order to find it in the app store simply search "Apple camera".

I hope this helps at least some of you.

Best wishes.
