Did the new firmware update for system and app on a Samsung Note 4 yesterday 5/10/18.  

After update:

1.  The controller battery discharges almost as quickly as the drone's battery.
2.  The camera pixelates badly.  Mainly the bottom half of the screen.  After moving it takes several seconds for the picture to catch-up. Changing resolution
       does not help.  
3.  The option to use the controller's stick for takeoff is gone.  I have to use the screen, then slide to take off.
4.  On the first flight I received an ultrasonic sensor failure message and warning to land immediately.  
5.  Upon landing  the drone decended normally and then fell from about four feet.  Fortunately it bounced in grass and was unharmed.  I received a motor
               bound message however the blades were not turning just twitching.  A second landing went fine.

Have you tried to refresh the firmware? if you have and this did not help roll back the firmware to the previous version.

Don't think so.  The controller said Ready to Fly.  There was a red Firmware update message scrolling across the top of the  screen toggling between that and a green ready  to fly.   The update message went away. Regarding returning to a previous version the DJI faq pages states once done you can not return to a previous version.

Did you update the Mavic and the Controller?

Hmm.  No,  Just the controller and phone.

All software updated.  I believe the drone had been updated as it was sitting nearby during prior update. Had not updated all batteries.  Still heavy pixelation.  Seems worst than before.  Have to fly RC style keeping it in sight as camera is useless when moving.   Flights seem smooth however I've only done one lift off and landing.

yes you cannot downgrade the firmware but you can refresh.  You should using DJI Assistant refresh the AC and RC firmware.  Then do a IMU/Gimbal/RC/VPS calibration then go to open field and Compass Calibration.  All in that order and completed 100% before trying to fly again to see if it helps.

Hi, sorry for the inconvenience that it may cause, may I have the firmware version of the remote controller and aircraft? Did you manage to uninstall and re-install the app? (ensure that files are saved) I would recommend resetting the camera using DJI GO 4 app as well.

The drone was sent to dji for inspection.  Per them the issue is due to physical damage and is not covered.  The repair cost exceeded $200.  I explained that the damage occurred immediately after a “required” update.  Speaking with a technician it was understood that the pixelation occurred on the initial post update flight and that the drone shut down and fell.  He stated he would update the repair request and send it higher for review.  It was denied.  I’m not paying for a repair not of my doing so the drone will sit as a paperweight or I can find someone who repairs on the side.  Or part it out.

DJI also returned the drone with the gimbal support not attached so the camera got to bounce around all the way back.  I’m sure that helped things.  

Back to RC.  

I left a scathing response to their request for feedback on their customer service.
