When I used to land the phantom 4 it used to hover over the ground and then when you hold down the Left stick it beeps and it lands very softy and safely and then shuts off.
For some reason it has stopped doing this and rather than land nicely if you hit down it will just land really hard.

Also Autoland just drops it really hard to the ground and it bounces multiple times (as if it does not know that the ground is there)

There are no sensor errors and the VPS does say the distance from the ground in djigo app but somehow it seems the drone is unaware the ground is there.

Why is this happening?


Thanks

What's the current firmware of the aircraft? Does the Precision Landing have been enabled?

Its not the newest version as that version messed up 100's of p4's so I dont think this version has precision landing

You need to update to the latest firmware. Also, consider calibrating the downward sensors through the Assistant 2 software.

I don't think I will be updating. I can tell you lots of people that I know who's P4 standards are ruined from the firmware update. I will wait until they fix it.

I will try the calibration of the sensors.

Thanks for your help!

That's alright. You can also try to calibrate the VPS system if you don't want to update the firmware, hope it helps.
