Hi DJI-Paladin/Ken etc.
It might be worth creating a separate post for best practice after firmware updates so the forum guys can refer to it easily?
My input:
After a firmware or software update I calibrate everything that can be calibrated (takes about 30 minutes):
IMU, Compass, Camera Gimbal, Obstacle Avoidance & Vision Positioning Cameras, Remote Control.
I then check all settings in the Go App.
I then carry out a flight test; handling, RTH (to landing), photo and video (post flight analysis).

In the case of a recent Android update to version 6, and PC Assistant 2, full check as outlined above.

Since we don't know the inner workings of the various components in an update, it is best practice (in my opinion) to re-calibrate everything, that way we know we have a balanced aircraft and control system.

In the case of firmware update 411, I am still getting a bit of vertical drift when I pause POI but that may be due to the change from horizontal flight to hover (allowing for the motors to affect the aircraft).

One issue I am having is the S1 and S2 switches sometimes don't action the camera up/down or camera settings options that I've set.

Overall, I'm loving the Phantom 4 and the new features.

Regards and safe flying :-)

What device are you using?
Is the recorded video from the SD card produce good video/photos?
When did this start happening?
You may need to send the unit in for repair.

Thanks for the input, I think all that is needed is a IMU, compass, and gimbal calibrations and check your settings, then flight test.
And are you said that you getting vertical drift now when coming to a stop and you did not get it in the prior firmware?
And when you say S1 and S2, you mean C1 and C2 correct? And you have one of them set to tilt up/down and you sat that that one does not work?

It will be a good idea to have such document or video; even though I have many years IT & flying experience, I am a bit puzzled what to do with my P4.
I am still using he original box firmware and I downgraded my app back to 2.8.1

I have done all calibrations mentioned above, except for:
"Obstacle Avoidance & Vision Positioning Cameras"

Please let me know how are those done; maybe I missed them.

To calibrate OA and Vision postion you need to downloads the dji assistant app on PC or Mac and plug the bird Into the computer

It's simply a case of aligning boxes on the screen and rotating your p4 while holding it Infront of it, while it is plugged in

Thank you for the tutorial video.

But this does not solve the problem.

I usually do this procedure.

The monitor signal is cut at the time of takeoff .
Sera that there is no solution to this problem ?
I am disappointed with the operation of Phantom 4 .
Very disappointed !

The Phantom 4 firmware is not just one big file like previously, its a collection of smaller module ...

Just for good order - I have found that you do not have to shut down the Go app between battery firmware updates.   Just power off the P4, swap the battery, power it back up again and if it needs updating the Go app will tell you that it is inconsistent and offer you the opportunity to update the battery firmware.

DJI-Ken, or anyone, please let me know the answers to my questions below:

If you use the pc and go  ...

I had already updated my P4 to 1.1.410. I thought I had also updated all three batteries but I missed one. Today when I connected to DJI Assistant to update to 1.1.411, Assistant displayed that I needed two updates - one to 1.1.410 (battery) and one to 1.1.410 for the P4. Both updates were successful. I powered down and swapped in both the other two batteries and connected them to Assistant. Both of them were already updated. No problems.

Just did a short flight from my backyard. Looks to be working well. Especially the loss of altitude after a quick stop. For me, the issue is now fixed. Thanks.

Hi there. DJI Paladin...do you know if this update has fixed the random resolution/bitrate lowering bug that has affected two p4's I've been using? One minute I've got beautiful sharp 4k, the next soft, mushy video...from the card, that is.

I guess I'd try downgrading , turning everything off, uninstalling dji assist, and then starting from the beginning if you're really struggling

Have you tried our recommended devices?

Hi Ken....it seems you are the guy to ask about stuff!! I have a iPad mini 2 (no cellular) ....two questions. Would the mini 2 perform worse than say a mini4 for example? Like I wouldn't want something like the app crashing because my device isn't the newest..... Also, because my device doesn't use cellular data I'm assuming the only thing that I would suffer is not seeing my device location on the map? Would I even still get mapping?.....and would hotspotting my iPad to my phone get rid of these issues? I would prefer to use my iPad to get the fuller experience (I have iPhone 6). Thanks for your time!

You replied to Paladin's post. If you reply to one of my post then I will see it.
Your Mini2 should work fine as it's on the DJI recommended list. The 4 may work a little better as it's a faster processor.
When your at home on your WiFi. just open the app and enable "Cache Map in the Background" from the General Settings menu. Then move the map to the area you are flying in and it will cache that area  for you.
Or sine you have a iPhone, when you get to your flying area just use your phone as a hotspot and get the new map data.

Thank you DJI!!!! NO MORE YOYO EFFECT!!!! Finally after updating to .411 and COLD IMU Calibration (I put P4 inside the refrigerator for 15 minutes WITHOUT BATTERY) then did quick IMU Calibration Cold. NO MORE LOOSING ALTITUDE!!! Only in Sport Mode when Quick Stop, goes up 1 meter then back down. I'm very happy and thankful. I LOVE IT!!! THANK YOU AGAIN!!!

This FW does NOT fix the altitude dropping.   I found yesterday test, that P4 aero design gains altitude when moving (depends on speed and more on lateral and head wind) then lose the gain acquired.

But the longer to move fast laterally, the more gain thus the greater drop when you stops.   Well, looks like this the con of having the sport mode.

Aerial photo does not need fast move, so its OK.  Why is not on P3 ?  the P4 has thicker hunchback ...

So this multitude drop will never 100% go away.  Just control your speed.

I had 1 problem while updating.  It changed my RTH altitude to 0 and it wouldnt let me change it.  It kept saying that RTH couldnt be set higher than maximum altitude even though it was set to 500meters.  I reset maximum altitude and then it would allow me to change it.  Check your RTH altitude to ensure it is set right..

Hi DJI-Ken,
You're right, I should have said C1/C2! And yes, tilt up/down intermittently does not work; can't pin down the exact circumstances for it yet.
No, I've been getting vertical drift on previous versions of firmware too. It's a lot less now but still a bit. However, I have been trying out different gain settings (for smooth video when moving) so maybe that is having a slight effect. I will try a flight with everything set to default.
Other than that, everything seems fine in terms of control and stability. I've done  a lot of POI, Waypoint, Tapfly trials so happy with that. Haven't used Activetrack as no need for it yet.
:-)
