Hello and good day JNIX. Thank you for reaching out and for the inquiry. Upon checking the iPad 4 on the recommended mobile device list for the DJI Mavic Mini and with the DJI Fly application. I am sorry to say that the iPad 4 is not recommended for the said drone and with the said application. I would recommend to use a recommended mobile device in operating and flying your DJI Mavic Mini for compatibility and reliability purposes. For reference I will post the list of recommended mobile devices for the DJI Mavic Mini and for the DJI Fly application. Thank you for your understanding and support.
