iPhone 17 Pro Max stereo audio recording problem

iPhone 17 Pro Max audio mode in video recording

1) Spatial Audio - Not for quality, Muddy/Muffle, Tracking with camera zoom, never use it

2) Stereo - Best mode so far, Stereo image audio

3) Mono - Nice sound but mono audio

All good on iOS 26

but with iOS 26.0.1

Wind Noise Reduction = Off

I found weird issues on iPhone 17 Pro Max

All Stereo footages got the same muddy/muffle sound with Spatial mode and filtered tracking with camera zoom which is not Stereo mode I've been used for many years.

Here is the footages

Now I have to use only mono mode to get full spectrum of audio and best sound quality

There is some bug..

Anyone has these issues?

Best
