Downward Sensor is Abnormal

[jagman08]

Hi all, I’m have this intermittent Downward Sensor error.Ive inspected the lower sensors, and they are clean . For what ever reason , there seems to be a common denominator when I install a Polor Pro filter. Could this be a possible issue? Removed filter, restarted the Phantom 4 , and flew 20 minutes without the error.

. DJI 4 , version4.3.17. Aircraft 02.000.700
All parameters are good in the App, lights on drone are normal, until the advisory pops upon the screen , then they go red . 29 wonderful flights, this abnormal condition started a few flights back , when I introduced the NDFilters. Maybe a coincidence, any input would help . Thank you

Try doing a vision calibration and factory reset with Assistant 2. Can't do any harm and it might just work.

Good luck!
