If that don’t work
Check if it’s working on Apple product.
If it’s works... yes ?
I think android has a bug in it
When I’m using android ( Crystalsky) and it doesn’t function
I turn on the Drone and connect the RC.
Wifi up Iphone or iPad select Histrogram
Then hot swap back to the android phone/tablet. Leaving the Drone & RC on
The Histrogram is displayed. You can do the same for camera display
Also overexpose warning if you also fly a Mavic or Phantom.It comes and goes but this is how I’m getting it to work
