Hello there. I am sorry for the trouble this has caused and thank you for reaching out. Upon checking the said mobile device ( Samsung S10 ) that your are trying to use on your DJI Phantom 4 and with the DJI Go 4 application. I am sorry to say that the said mobile device is not recommended for the said drone and with the said application. We would suggest using a recommended mobile device for the DJI Phantom 4 and with the DJI Go 4 application for compatibility and reliability purposes. There is a possibility that the Samsung S10 will be able to work on the DJI Phantom 4 and with the DJI Go 4 application. But however, since it's not yet optimized with the said drone and with the said application we cannot guaranteed if it will work all the time and if it will be able to run all the functions of the DJI Go 4 application while using it on the DJI Phantom 4. For reference, I will post the list of recommended mobile devices for the DJI Phantom 4. Thank you.
