Keep image of Firebase once loaded Android

I'm trying to create a Activity where you can set a profile image by uploading it to the Storage of Firebase from the gallery through a upload button, and the idea is to remain saved in that activity, but when going on activity, this photo is reset by the one it initially had in gray. I would like to know how I can do to save the changes in the profile photo and that it will not be changed unless another photo is selected.

//pasa la foto al storage
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);

    //VERIFICA QUE SE HAYA SELECCIONADO UNA FOTO
    if (requestCode == GALLERY_INTENT && resultCode == RESULT_OK) {

        //si todo sale  bien entonces cargamos la barra de espera

        progressDialog.setTitle("Subiendo...");
        progressDialog.setMessage("Subiendo Foto");
        progressDialog.setCancelable(false);//para que al clickear fuera del cuadrado no se salga
        progressDialog.show();

        Uri uri = data.getData();
        //recibe la ruta de la foto o el nombre del archivo
        final StorageReference filePath = miStorageReferenceImagen.child("fotos").child(uri.getLastPathSegment());

        //sube la foto a la carpeta en storage que acabamos de crear
        filePath.putFile(uri).addOnSuccessListener(new OnSuccessListener<UploadTask.TaskSnapshot>() {
            @Override
            public void onSuccess(UploadTask.TaskSnapshot taskSnapshot) {

                progressDialog.dismiss();//finaliza la barra de carga

                //OBTIENE EL URI DE LA FOTO
                filePath.getDownloadUrl().addOnSuccessListener(new OnSuccessListener<Uri>() {
                    @Override
                    public void onSuccess(Uri uri) {
                        //la librería glide se añade al gradle app y al project, para guardar imágenes en caché etc
                        Glide.with(getBaseContext())
                                .load(uri).into(civPerfil1);//con fit center y .centercrop se acomoda la imagen pero solo sirve para los images views
                        Toast.makeText(getBaseContext(), uri.toString(), Toast.LENGTH_SHORT).show();

                    }
                });
            }
        });

    }
}

//metodo subir foto
public void subirFoto(View v) {

    Intent intent = new Intent(Intent.ACTION_PICK);//escoger imagen de la galería
    intent.setType("image/*");//abarca todos los formatos de images
    startActivityForResult(intent, GALLERY_INTENT);

}
