Litchi does not connect to Mavic Pro on OnePlus 7T, LG G4

Litchi is supposed to connect to the controller, not the drone.
The controller connects to the drone.

Post a screenshot for each device.

On all of my phones (Samsung J5 not tested yet) I can log in, check the license and download the DJI database. Google Maps is also working, location, permissions ok.

All these do not require a connection to the controller (drone).

@Sami_Jumppanen

Would be nice to know which factors affect the connectivity.

The most common factor is USB related:
-Faulty USB cable
-Faulty USB connector on controller and/or phone
-Dirty USB connector (accumulated dust and/or lint).

Have a look at this thread:

DJI Mini 2 Camera Feed Shows Blank Screen Until Recording

Hi everyone, A month ago, I tried using my DJI Mini 2 after an update, and suddenly the camera feed on my phone only showed a blank white colour screen, though the drone flew just fine. I did not touch it for a month and tried again today. Now, I noticed the camera feed works fine if I start recording. Has anyone else had this white background screen issue? Any ideas on how to fix it or where I could find more support? Thanks!
