Recorded audio files are corrupted on some Android devices

[DigitalLabSlash]

Has your issue been reported?

• I have searched the existing issues and confirm it has not been reported.
• I give permission for members of the FlutterFlow team to access and test my project for the sole purpose of investigating this issue.

Current Behavior

We record the user voice, send it to supabase, then download it back to the app for our user to be able to listen to his voice.

It works perfectly for some Android users, but for some others, the recorded audio file is corrupted and can't be play (even on supabase).

Expected Behavior

Recording Audio should not produce corrupt audio files, no matter the device.

Steps to Reproduce

1. Create a recording
2. Send to supabase
3. Try to play the audio file with wavesurfer.js or any other player.

Reproducible from Blank

• The steps to reproduce above start from a blank project.

Context

Imposible to release our app

Visual documentation

https://peoplesnap.slash-digital.io/ripite/Esteban.mp3 --> Recorded from Android 14 device, works perfectly
https://peoplesnap.slash-digital.io/ripite/Jean.mp3 --> Recorded from Android 12 device, corrupted audio file

Additional Info

We don't know why some Android devices produce corrupted audio file when using the recording widget. It's "constant" : a device that works will always produce good audio files, a device that doesn't "work" will only produce corrupted audio files using the recording flutter flow widget.

Environment

- FlutterFlow version: v4.1.34
- Platform: Android
- Browser name and version: Not aplicable
- Operating system and version affected: Android

It seems the bug also applies while recording through the web interface

Hi @DigitalLabSlash, thanks for your report. Can you please share the list of devices you tested with the following data: brand, model, OS version.

We also need the bug report code (you can get it with a right click on the widget in the Widget Tree).

Hi Paul,

Thanks for your swift reply,

Here is the bug report code :

So far in my testing :

Xiaomi M2011K2G Android 12 : recording is corrupted
Samsung Galaxy S24 Android 14 : recording is fine
Iphone6s: recording is corrupted

Also : looks similar to this : #2316
Could be that Supabase + Some Android devices would cause trouble.

Thanks for you help
