Samsung S21 - Captured images are not showing up in gallery app

In our app, There is a camera photo capture feature and its capture images successfully and saved in External storage(/storage/emulated/0/DCIM/Camera/Appname/foldername). But its not showing up in Gallery.
Camera API : Camera2 API

Code we use to save the captured images;

 private void  saveToPublicStorage(Bitmap bitmap,File file) {
    FileOutputStream out = null;
    try {
        if (Build.VERSION.SDK_INT > Build.VERSION_CODES.Q) {
            out = getFOSForPublicCameraDirectory(file.getName());
        } else {
            out = new FileOutputStream(file);
        bitmap.compress(Bitmap.CompressFormat.PNG, 100, out);

    } catch (IOException e) {

private FileOutputStream getFOSForPublicCameraDirectory(String fileName) {
        FileOutputStream fos = null;
        ContentResolver contentResolver = getContentResolver();
        Uri imageUri = getURIForPublicCameraDirectory(fileName);
        try {
            fos = (FileOutputStream) contentResolver.openOutputStream(imageUri);
        } catch (Exception e) {
        return fos;

private Uri getURIForPublicCameraDirectory(String fileName) {
        ContentResolver contentResolver = getContentResolver();
        ContentValues contentValues = new ContentValues();
        contentValues.put(MediaStore.MediaColumns.DISPLAY_NAME, fileName);
        contentValues.put(MediaStore.MediaColumns.MIME_TYPE, "image/png");
        contentValues.put(MediaStore.MediaColumns.RELATIVE_PATH, Environment.DIRECTORY_DCIM + File.separator + "Camera" + File.separator + "Folder1" + File.separator + "Folder2");
        return contentResolver.insert(MediaStore.Images.Media.EXTERNAL_CONTENT_URI, contentValues);

Also this same piece of code working in Samsung S21(Android 11).The problem is only with S20. I have followed Pictures in the My Files app are missing from the Gallery app and checked all the given scenarios and nothing helped.

I have the same problem with my Samsung Galaxy J5. What i had done was went to “My Files>SD Card” and from “More” chosen the “Show Hidden Files” then search for “.nomedia” file. Then deleted all the “.nomedia” files. Then my problem was solved.

Thanks @Roberts652 …I have checked that too…it didn’t helped me either…Do you have any other suggestion?
