I have had my Mavic Pro 1 for quite some time. It has always worked well

The last time I tried to use it, stopped connecting.

I use the controller and my samsung phone.

Any help or advice?

Hi there. Thank you for reaching out and we do apologize for the trouble. Can you please confirm if you are having issues with linking the aircraft to the controller? Please try to download the DJI Assistant 2 software on your PC and please update/refresh the firmware of both aircraft and remote controller. You may also try to manually link the controller to the aircraft using the combination button. Please keep us posted. Thank you.
