Google 2-Step Verification (Android) Google prompt does not send to every phone where signed in

For Google 2-Step Verification (Android) Google prompt, from Google UI, it states that 'After you enter your password, Google prompts are securely sent to every phone where you're signed in.' But, that is not true. I have 3 phones which are signed in. But Google prompt keeps popping up only on one phone. This annoys me much because I don't take that phone with me all the time. I don't want to sign out that phone because I need to use it sometimes too. How can I let Google prompt send to all the signed in phones? (OR temporarily block that one without signing out)
