Ok Guys,

I am having an issue with my Mavic and I am wondering if anyone else is having the same one.

I flew my Mavic almost every day for 3 days and had no issues.

I was out flying on the 3rd day, had no issues all day but did one last flight and found that my drone would not land... Instead of landing it looked like the downwards facing sensors/cameras were stopping it from lowering. I would attempt to lower the Mavic and then it would stop and just start going up. So the Mavic didn't just not land, but it would also start ascending and I wouldn't be able to lower it. I was able to land the Mavic with the Auto Land feature.

There was a firmware update that night so I updated the Mavic and I am STILL running into this issue.

I was able to find a workaround by turning off all object avoidance and downwards vision positioning.

Has anyone else ran into this issue?

Also, I made sure that I was calibratiing the compass before each flight.

Thanks,

There is nothing on the bottom sensors.

I even cleaned them with a Polar Pro lens pen that I have just in case and had the same issue.

Seems like multiple people have recently been reporting this issue. Some said that holding the left stick down eventually made it do a controlled landing

Yup that is how I have been landing it.

I have been forced to disable the Downward Vision Positioning.

I am hoping that there will be an update that fixes this...

This is not a bug, this is a 'feature'.

Yes the auto land is a feature but the Mavic is unable to land even when it is no where near the ground.

It will be high above the ground with nothing obstructing it and once I start descending it just hovers and starts ascending again.

Can you film it? Manual says 1 second... before landing.

Could you please make a video of this issue?
Also please sync your flight records and provide me with your DJI account email and the date this occurred.
I'll help to check it.

I have this exact same tissue - and this must be my 10th DJI product this year and my second Mavic.

Theres a setting in the vps that it will check for ground smoothness before landing maybe try disabling that and see if it works

I had the same thing happen to me today (12/30/2016). I put my Mavic up for a quick shot and it would not land. I got an obstacle warning but there was not obstacle. The LZ was hard packed clay. I moved the Mavic to a grassy area a few feet away and it still would not land. I flew it over some tarmac, still showed a warning. By this time the battery was critically low and I started to panic a bit and didn't think to turn off downward vision and the drone plopped to the grass when the battery died. The Mavic is okay but I worry about what that did to the battery. I hope this never happens again but after reading this thread, I have a feeling that it will. Thank you for posting and I hope DJI corrects this.

I've had several DJI drones including P2V+, P4, P4P, I1, I1Pro, I2 and now, Mavic. Mavic had its second outing today and wouldn't land. Kept trying to takeoff  into trees above. I'd lower it bit it wouldn't come lower than about 5 feet. Then it just started to climb again. I therefore hand caught it and tried left stick down, then CSC but it wouldn't stop. Eventially another version of CSC seemed to initiate a power down but not until after I'd spent an few minutes holding my very angry Mavic against its will. Time to take another look at the manual...

I even cleaned them with a Polar Pro lens pen that I have just in case and had the same issue.

You say you cleaned it with a lens pen?  The ones that use carbon?

This may also be an issue. You see, the way the pens works is it uses carbon molecules.  These carbon molecules cover the surface sometimes of what you are trying to clean.  You can actually see the carbon sometimes when you clean a DSLR lens and do not do it properly.  This is also the reason why people wipe their windows on cars with newspaper.  The printing ink is also made with a carbon compound.  Anyone who has ever used newspaper knows what happens sometimes, the window takes the carbon and you can cleary see it.

I am not saying this is your case in particular, but be careful and double check those sensors and clean them with normal damp cloth.  Maybe some carbon is smeared on them and causing issues for those sensors.  They are very sensitive.  I can see a thin carbon film casuing these issues.  Carbon is dark and shows up in pictures as dark spots.  So, it is plausible they are causing a similar effect and making the drone think it's not safe to land or something.
