Confirmation login dialog does not appear in facebook api, google+ api, vk api

Question

My question is a little broad, but in case someone had same is very possible. After first launch facebook, google+ and vk.com asked me to confirm requested permission (for example, facebook: "public_profile, email, user_friends"). But every next time the confirmation dialog did not appear. I cleared cache, I reinstalled app, but still nothing. Maybe I lost something? Or facebook remembered device and doesn't ask confirmation second time? I still have information I requested, but without confirmation. Google+ even doesn't open its Activity, just straight away shows me the result. For example my facebook code.

My GrahRequest is same as in docs of facebook api and I execute it in onSuccess() callback which I added to LoginManager. Permissions I set to LoginManager aswell as: LoginManager..getInstance().logInWithReadPermissions(...).

GraphRequest request = GraphRequest.newMeRequest(
    accessToken,
    new GraphRequest.GraphJSONObjectCallback() {
        @Override
        public void onCompleted(
               JSONObject object,
               GraphResponse response) {
            // my code
        }
    });
request.executeAsync();

Any explanation is very appreciated, thanks.

Once the user accepts the permissions for an app, if the app asks for the same permissions from the same user, no re-confirmation will be needed. The only time another confirmation will be needed is if you ask for more permissions, or if the user has de-authorized the app from https://www.facebook.com/settings?tab=applications.
