Good night, pilots. I have a serious problem and would like help. I've done 40 flights with my Mavic Pro purchased a month ago. On my last flight, the DJI Go 4 app now always gives Disconnected. I've done everything possible, I've followed all the tutorials I found on the internet and nothing worked. What happens is that none of the USB ports connects to my cell phone (I have a S8 + Samsung), the control does not recognize the phone, nor does it appear the charging mode of the phone. I've already taken the following steps: I uninstalled and reinstalled the DJI GO 4 app, I already changed the cables, I already upgraded and downgrade the control and the drone, I already did the usb debugging, I already made a new connection between the control radio and the drone, already I did all this using 3 different cell phones with different Android versions too and NOTHING SOLVED. The control mode via wifi is working normally with my cell phone and the RC also connects with the drone normally. Other than what I have seen with others who have had a problem similar to mine, in theirs the control is in the mobile charging mode but does not connect with the DJI GO 4, so they solve by taking some of the actions I mentioned above and that I also tried. I wonder if someone has already gone through this and how did you solve it? I do not want to have to buy another control (and before they ask, I can not ask for an exchange with the seller anymore). Thank you very much in case anyone can help me.
