Finished a successful firmware upgrade yesterday. Today was the real test. All went well but I did notice a distinct wobble with the aircraft. Tried all the intelligent modes. The DRAW function performed well however the wobble factor was insane. I had to cancel this mode to regain control. Has anyone discovered a fix for this issue? Hopefully DJI will sort this issue.
Taking the bird out for another fly later today will report on any other issues

I flew mine again today for some commercial real estate work and it's very disappointing that what was once a dream drone to fly has now become a real chore. The occasional bucking is really annoying and takes away any enjoyment out of flying.
It's a shame that this update has been a disaster because the other new features work perfectly and could  be very useful.
Despite the new features, I would far prefer to revert back to the previous software with its smoother flying.  I hope that DJI will provide a means to do so.

General experience since the firmware update, along with a full set of calibrations, has been good.

1.        Hover and normal flight seem about as before.  The controls do seem a bit more sensitive at times.  Not seeing any issues with range or height so far.

2.        I am getting wind warning I didn’t see before.  Usually there is some wind, but not that much it seems.

3.        Landings are much more stable and gentle and slow.  This is a very good addition.  Landing protection will also kick in at times if the ground below is detected as unsuitable (lighting seems to be a player here).

4.        Video seems more stable with fewer drop outs than before.  Seems smoother than before.

5.        Terrain follow mode seems ok going uphill, but seems to have little effect going down hill.  Will try this more at a different location with more room and slope differences.

6.        Tripod mode seems fine with all the controls slowed down as expected.

7.        Gesture mode seems fine, is easy to control, and takes good pictures when needed.

8.        TapFly mode seems more accurate than before with the addition of visual tracking path on the video display.

9.        Draw mode seems to work well…most of the time.  When using at low altitude and slow speed, drone wobbles some during flight.  When using higher speed at more altitude, seems quite smooth.  Like the TapFly, it includes a green path on display of path and current position on it.

10.        Have not yet tried the new sub modes for ActiveTrack or TapFly.

11.        Seeing fewer authorization warnings than before.  I live near the edge of an Enhanced Warning Zone.  Before I used to get the authorization confirmation (with the two confirm check boxes) almost every time at takeoff.  Now it seems rare.  I do a weekly video of a local bridge construction project.  Before I saw these warnings every time the drone passed the center point of the bridge (even within the same flight).  Now I don’t see them at all there.

12.        Obstacle avoidance seems more sensitive than before.  I see warnings sooner and it seems to slows down more than before the update when near obstacles.

13.        Many of the settings (max altitude, RTH height, etc) are defaulted after the update.  You may have to reset these to your desired values.  This may also be the case for the sensitivity settings in the Advanced Settings area, but I cannot confirm this as I don’t know what mine were before.

DroneGuyEd,

But was it truly a Precision Landing or just a very close regular GPS landing?

What I know is that its different and improved from before.

1. At take off, it generally rises to about 4 feet.  This is unchanged from before.

2. I see no record take off option, but only ones for protected landing and precise landing (both checked).

3. When descending, it initially goes to the approximate take off point using the RTH altitude.  It tend goes down fairly fast, until it gets maybe 30 feet above the ground.  As it comes down it adjusts both its position and pointing direction to match that from takeoff.   It then slows quite a bit, then slower still at about 6 feet.  It eases onto the ground quite slowly at the last foot.

Drone Guy Ed... I think i figured out terrain follow... It sets a minimum altitude so when going uphill it adjusts to maintain the minimum altitude but when you go downhill you never meet the minimum altitude as the ground is falling away from the drone.  While flying downhill if you hold the throttle down (descend) it will descend to the minimum altitude but no further. It seems counter intuitive and dangerous to hold throttle down while flying forward at a low altitude but it works.

Well, after a full day (literally) of test flights, I did not get much beyond trying to determine a workaround or cause for the "bucking" & "Twitching" flight, as well as the chronic loss of video transmission.

Both my P4 and my P4P buck during flight.  The P4 is totally unstable after the update (bucks too hard)  and I don't dare fly it.  The P4P is much better, but still does not have the stability it should.  I see it "wobble" too much in flight, especially in the Draw mode where it nearly flips itself sideways.

Neither drone seems to track as well as before the update, at 20 feet or less, they both drift horizontally during in what was previously straight as an arrow flight.  Once the drift was so dramatic that I thought I might have switched to ATTI mode by accident.

In addition, I am getting a ton of transient issues, usually resolved by waiting, or rebooting.  For example, on one launch I booted the P4P and was met with a red IMU error (I don't recall the exact text) saying that my IMU had a problem.  At the same time, the lights were solid red on all four corners of the drone.  I paused for a few seconds to try to understand what was happening, then suddenly got a green clearance to fly and the lights on the drone went to a normal pattern.  I checked the IMU status panel and had all green.

I have gotten quite a few transient issues like this, that I had never seen before the update.  They will appear, confuse me, then go away (either from waiting or from rebooting).  Probably once every four or five flights.

Has anyone tried to make adjustments to the Gain, ESC, etc. after the upgrade to see if you can get the P4 to fly smoothly as before the upgrade?

I personally plan to stick with last summer's firmware and RC. if it works, don't f*** with it.

After upgrade I had shaky hover, did a refresh with dji assistant ( that went fast) then a IMU calibration
then reset sensitivity settings to default and it flies like it did with old firmware.

I was told earlier today that I need to update batteries aswell,
I updated the controller & aircraft through dji go4
Had a test flight with no issues
But couldn't get assistant on my iPad which I found out can only be on a pc.

Managed to get assistant downloaded onto pc so I connected up my drone with battery 1
All ok

So connected battery 2 into drone & connected upto assistant software, this time I get an upgrade bar so I press & upgrade, and again everything ok

Is this right what I have done??

I personally plan to stick with last summer's firmware and RC. if it works, don't f*** with it.

Yesterday I had my first flight after updating an callibrating everything; when flying fowards and backwards and I slow down slighty the speed (a very soft right stick release) it jerks a lot, and the gimbal is unable to handle with it, so the video footage wobbles. Today I have done a new test. Yesterday I recalibrated the whole system and today the Compass before the flight. I have lowed brake sensitivity to the minimum (70) and attitude to 50. I have reduced the pitch gain to 85 and I have been making modifications. My impressions:
1.-The Hover is very stable, more than before the update.
2.-It seems that the problem of the horizon has improved a lot, it do not tilt with the turns. Anyway I have to test it to the sea shore to confirm it, with a completely flat horizon.
3.-Flight modes work fine, but I'm not much fan of automatic modes, so I have not tried much.
4.-The problems of aggressive braking are maintained despite of the multiple variations of the gain, sensitivity and exponential parameters. There do not seem to be significant differences between some parameters and others, as if it did not change anything at all. In fact the braking distance seems the same with the sensitivity at 100, at 85 and at 70.
5.-It seems that the stability of the gimbal has improved slightly compared to yesterday, the image no longer vibrates so much in braking (it is also true that there was no wind at all today). But just when accelerating you see for an instant the propellers (it was not in sport mode) and when braking you see the propellers and even the tip of the front arms, at speeds of less than 10 m / sec, even at 6 m / s before braking !!!!!!!.
6.-No problems with video streaming, but did not move more than 500 m.
7.- I get 2 flying time minutes less per battery

Sorry for my English. Not a good update for me. I liked the smooth response to orders my bird had before

Does this fix the APP crashing issue on Android?  Specifically the Nvidia Shield tablet?

Probably you have Android 7 - Nougat installed. Downgrade it to 6 or 5 and everything will be fine.

How do you turn down the Sensitivity and EXP settings for Tripod mode?
Currently it is easier to fly smoothly in Normal GPS mode than Tripod because I have the settings turned right down in Normal but don't see how to turn them down in Tripod!

Also, I noticed that after exiting ActiveTrack mode it put all the EXP and Sensitivity settings to what appeared to be Sport mode, even after I changed to Sport and back to Normal it responded dangerously fast given that I was moving sideways after RTH had left it at about 3ft - below head height - after RTH being a meter out and it deciding the landing spot was unsuitable.   "recision Landing" was enabled and did nothing.

Flew very nicely in a 36km/h wind, the high wind warning was correct

I have Android 7 Nougat on my Galaxy Tab S2 ( a DJI-unsupported device) and the Phantom 4 behaves perfectly once connected.  However, I have NOT performed the latest upgrade, and Keep WiFi OFF (ie Airplane mode) to ensure no unwanted meddling with an already satisfactory setup

Upgrade went ok.  So.. what's the deal with needing to log in otherwise we can't fly more than 30m away and 50m high?  Is that each time we plan to fly or just once after the upgrade?  My Galaxy Tab S2 is wifi only so I have no way to always log in to DJI on location.

As far as I can see, if you sync your flights after updating Go 4 then there will be no issues, I've flown where there is definitely no mobile signal, my tablet doesn't have mobile anyway and I don't think I have logged in to anything since before the upgrade - the new Go 4 must have managed to log me in without asking when I synced the flights.

If one thing alone makes the update worthwhile it's that the horizon levelling works well.

I agree, fixing the Tilted Horizon issue is the ONLY real reason that I may risk potentially infecting my P4 with a severe case of the shakes...

Initially I saw a lot of wobble in flying for the new Draw Mode at slow speed.  Today I did a bit more testing.

The wobble seems related to  altitude.  If you fly below 30 feet, and use the min 2.2 MPH speed, it wobbles very clearly over the drawn route.  If you use the same route and speed as some distance above 30 (like 45), its smooth flight.

I think this is related to the downward vision system which has a limit of about 30 feet above the ground.  Somehow Draw flight below 30 feet gets confused by the downward vision system and wobbles, but draw flight above the 35 foot range is smooth.

I wouldn't count on the update fixing the horizontal issue. My drone got the shakes, and the horizon tilt is worse than before. I have to calibrate the gimbal before every flight. I've tried reflashing the firmware, recalibrating everything there is to calibrate. Waiting for a fix...

I haven't tried Draw flight but the wobbling occurs at all heights and speeds with my drone so I don't believe it's VPS related.

Well that update has screwed with my gear. Updated which took a while. Update got to 99% then gave me a message to disconnect cable and reconnect. Dumb or not I followed the instructions. Now my controller flashes red and green and the aircraft connects and disconnects. I am abroad and can't do anything about it until I get home where I have a pc. I get updates are important but some more flexibility is needed I shouldn't be forced to do it in order to fly. What a lot of crap

Same happened to me and even though there was a warning not to disconnect or restart the drone, I did, and that seemed to fix the issue as it completed once it had restarted. It took an age and I was doing it remotely though using the 4G connection and directly plugged in to my iPhone to do the updates so I was relatively impressed but it could be done quicker and clearly its buggy still..?

Hello guys.
I flight tested my P4 and I feel really concern about the wobbling at any altitude. Also I saw the propellers more than normal and flying in "P" mode. I'll wait until a new update is release.

Oh man, what are you doing to me!!!! I have fully talked myself into not upgrading to the latest firmware, because of all the reported issues. Now you show me the only thing I really want, a nice, flat, perfect horizon with the new firmware!! I must resist the urge to cripple my quad....

So, have you noticed any issues whatsoever, or is your P4 flying perfectly, with all of the new features AND a NON-tilted horizon?  If so, how many flights have you tried / tested so far?

Congrats on a very flat horizon!

I've done about 5 flights with the new firmware, all had good horizon lines with no "bucking". I've got some longer flights planed this weekend.   My one caveat was I didn't do any calibrations following the upgrade.  It said all sensors normal so I just flew, now i'm nervous to do any calibrations.
