Sorry but thats not an iPad 2 for sure

iPad 2 is not compatible with iOS 10 . I wish it was

My fault, sorry. It's an iPad Air.

After re-linking the RC I went out for another test:
- every time I turn it on I get IMU error but that goes away after IMU warms up. I did several calibrations.
- it's less noisy
- it auto-lends smoother
- in Tripod mode works well
- in Draw Mode, at the end of the mission it wobbles a lot and it stops wobbling as soon as you cancel the mode.
- in Normal mode, I was flying forward at 40m height and it suddenly accelerates and it goes on one side. I can regain control but it's scary.

There are too many reports of malfunction to be just user error.

It's like the wobbling issue is related to Obstacle Avoidance sensor. When OA is disabled, the wobbling will stop but the P4 will act like on sport mode.  Can someone test with the OA disabled?

Thank you, I have forwarded both files to engineers.
Just to verify, do you have the video saved for shaking situation? If so, please provide it to us as well.

Me too P4
1/ IMU calibrate warning every single start up
2/ Jerky unstable flight even with softer exp/gain settings
3/unstable week transmission signal even at close distance
4/sudden transmission feed shut down or gimbal malfunction swithcing off to weird angle.

hope we dont have to wait six months for an update to fix- would be nice to be able to install previous version as none of the issues I am having were present day prior to firmware update,

I was excited to bring my firmware updated P4 on my vacation, but it turns out to be a misery.  It's so very unstable when flying. Video transmission keeps dropping out, gimbal will suddenly crooked sideways. Most scary of all is the drone will all the sudden fly sideways by itself.  Happened twice, almost crashed into ocean.  I had a very reliable phantom 4, please let me downgrade to previous firmware.  Thanks.

I have tested with OA off and also VPS but neither makes a difference. I'm certain that the DJI developers know exactly what is causing the problem already. The real test is to see whether they will come out with a fix in an acceptable timeframe. Until they do, users like myself are left with a device which can do little more than sit on a shelf.

I am pretty sure the wobbling stopped with the OA off. I will try it again tomorrow, you might right. Hope the will release a fix soon, I am wasting my time off...

I am having similar issues with my Phantom 4.

1. IMU errors
2. GPS errors
3. Transmission errors
4. Gimbal errors
5. Aggressive flight inputs by the drone on its own (at times)
6. To high wind velocity errors on a calm summer day

I use both android and ios and the problem is the same.
Using the drone for professional work makes this firmware a huge problem for me.
Hoping that DJI is able to release a firmware upgrade soon as I have a project coming up in a week or so.

I know it was my choice to upgrade the firmware, but why should I not do that?
I expect DJI to test the firmware before release.

Hard time believing they did test it.
If they did then they did not test it on many drones, only a few.
On the look of things this issue is happening to most of the phantom 4 users.

With out a doubt a firmware issue.
Good thing I am used to fly in atti mode or I would have lost my drone a few days ago because of IMU and GPS errors.

This is my Bug experience after the latest firmware update of my PH4:

After I successfully updated the new firmware v.02.00-0106 of my PH4 I started to have the problem documented in the attached videos. During the flight, though a few meters away from the radio control, the camera stops working for a few seconds (with loss of video signal) and then positions itself as documented in the last frames of the attached videos. The video signal stops for a few seconds and then returns to the right or left sloping camera.

Please solve it immediately with a new firmware:

Guys - look at the two videos, in the hovering shot the machine is sitting behind a wall with eddy's of wind disturbing it - on the other the tips of the trees are bent over and blowing 10-15+ mph!

You can not do any stability or as you say; wobble test, unless the air is dead calm. Most of the movement you see in the videos is nothing other than the processor correcting unwanted movements.

Keep in mind. there is no way any drone is going to sit still in disturbed air!

My only glitch today in about one hour of flight time was a Gimbal that flipped over to one side (corner of landing gear seen) followed by a 3 second loss of video feed. That was my only negative point in all three flights (3 batteries).

I have that problem 7-8 times in a 15 minute flight with signal disconnect at as little as 30 feet. Have to restart recording each time. I have good pictures of left and right landing skids if anyone needs them.

I have started another Thread to try and collate all information regarding this. Have a read there is a work around mentioned there if you can work with 1080P.

I have asked for advice on how to downgrade until this is fixed  in both PMs and in these threads and, on each occasion, the request is simply ignored.

JodkC, I have been able to downgrade after the update, through Assistant 2.
After the update, it seemed to hover erratically,  suddenly changing altitude (by at least 5 feet) without any input from controller.  I was flying in a rather tight place, so I immediately brought it back.  Next flight, camera gimbal suddenly went askew.  I was yawing around doing a 180 panoramic series, when suddenly, the camera gimbal got stuck on the side so that all I could see were the landing gear.  The bird began flying erratically, so I felt lucky to get it back.  I immediately downgraded the version on the aircraft, and have had no issues since.  Not sure when I will reinstall the upgrade, until I hear these issues have been dealt with.

I just heard from Customer Service (DJI) asking is I did the upgrade via DJI Asst 2. And they even send a Youtube link showing how to updgrade as well as downgrade. Yes I used DJI Asst 2. Did not help. And there is NO way to downgrade. UGGGGHHHHHHH!

I can see no option to downgrade in DJI Assistant 2, only an option to "Restore Factory Defaults" which does not downgrade the firmware.

I was on line with DJI On-Line support last night. Tried 5 different things (all calibrations, restore factory settings, refresh, etc. NOTHING WORKED! I constantly lose signal. Almost every 20 to 30 seconds. Comes back, lose it again. They finally told me it must be my Android Turbo.   So wanted to down-rev. Not available!

The same problem here. After the update i loose signal 80 metere away from me. How we fix it?? You know where is the problem?

Today I tested the new firmware. Autostart and landing work, the landing has been softer. In the P mode, normal flight of the P4 until the stick is fully forward or backward. Initially normal flight, but shake in the middle as if the stick had left the end position at short notice. It looks like when you release the stick to make a full braking in the air. Same behavior in S mode. With RTH only a quiet return flight, then also short jerky brake tests. Conclusion: The sensors seem to be sensitive to this update, which is the lightest wind triggered wild counter-actions. It would be appropriate for RC and Copter P4 to reintroduce the rollback function in the APP and the Flightassistant.

Sorry about your mistake. After updating I have all the issues described here too. All. I really envy people who say they have no issues after the firmware update.........but ........is their threshold of tolerance to flight and gimbal behavior or image quality the same than mine? How many of them has done as many test as me after updating? How many of them are simply DJI groupies?. Sincerly, as so many different people having the same issues worldwide I can't believe anybody having no issues.

I wasn't in the air for 3 minutes before I noticed all these new firmware issues too,
Luckily, I;ve been able to downgrade firmware & she's flying as before,rock solid, might be just me but seems faster too.
I;m not even going to think about upgrading again!

Pathetic. And, I see no response from DJI. I'm lucky-this has only been a problem for me for the last two weeks, as I haven't used my drone since this. It worked fine....until the upgrade was forced on me. I did try calling, and was told to simply downgrade using the "assistant"-but we all know that doesn't work.
There appears to be no solution here....which probably explains why DJI is so silent.
I won't bore people with re-iterating what they are seeing.....it's the same crap I'm seeing.
Let's see:  who else makes drones?  A real shame. I really thought this was a nice machine.

The same thing happened to me since the last update, video cuts, signal cuts and shakes. I have only tried to record in 4k. At 30fps.
I do not understand how DJI can get firmware so little worked.
