Some app account is tied to my phone even after reinstall or change my google account on my phone. Why this app could know my phone?

    Provide the app name and more details concerning your predicament kindly. Also is the app logged in with your Google account? And what exactly is the issue? – user145490 Jul 7 '16 at 7:50

    This may be due to the app being able to retrieve either your Android ID or your IMEI. – Grimoire Jul 7 '16 at 8:41
