android.system.ErrnoException: open failed: EACCES (Permission denied)

I'm getting the following errors when running on an Android emulator and physical device (Note 8). The functionality is fine and there doesn't seem to be any problems with use, but the error messages are long and continuous:

This keeps repeating for as long as the video chat is open.

have you granted file system access to your app?

have you granted file system access to your app?

Thanks for the fast response!

I'm not exactly sure how to do that or how to confirm. These are the permissions I have in my AndroidManifest:

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.READ_PHONE_STATE"/>
    <uses-permission android:name="android.permission.RECORD_AUDIO" />
    <uses-permission android:name="android.permission.CAMERA" />
    <uses-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="android.permission.BLUETOOTH" />

Do I need to add a permission here?

Update: I've added the "READ_EXTERNAL_STORAGE" permission to my AndroidManifest but the error is still showing while in a video call.

@oplattethunder this is a bug from our native SDK, but you can ignore it because it just throws logs to the logcat.

First, check whether you have implemented scoped storage logic in-app. You can also use android:requestLegacyExternalStorage="true" But this legacyStoragePermission is limited to version 10. You need to implement scoped logic.

Also, check whether your targetSDKVersion value is 30 or greater or not, this is needed if you are using the app in Device android version 30 or more.
