   I have new phones to add, i thought it was device specific but no unfortunately :

   • Realme C53 : Android 14
   • Itel RS4 : Android 13

   It causes so far 20+ crashes, much less than #375 which has more than 100 crashes in my app so far

   Hello @Tom3652, Could you please specify the types of files users are allowed to pick or the format in which audio is being recorded for android users? I believe this information will help in further investigating the crash.

   Hello @manoj-simform , yes sure here is the code for the recorder and it's saved as an .mp4 file :

   recorderController = RecorderController()
           ..androidEncoder = AndroidEncoder.aac
           ..androidOutputFormat = AndroidOutputFormat.mpeg4
           ..iosEncoder = IosEncoder.kAudioFormatMPEG4AAC
           ..sampleRate = 44100
           ..bitRate = 48000;
           
   String outputPath = "${dir!.path}/${DateTime.now().millisecondsSinceEpoch}.mp4";
   recorderController?.reset();
   await recorderController?.record(path: outputPath);

   After that, we upload that .mp4 to our serveur.

   When they read the file, it's from the server URL so we download it first locally as .mp4 file and read it.
   The file read on Android may come from an iOS recording if that helps.

   Hey @manoj-simform I have a new info on what is going on wrong, instead of Error 0xe it's written codec is released already:
