Tony, do you refer the P4, instead of P4P, right? If yes, we're sorry for the misunderstanding as the beta we mentioned here is for P4P only. Currently, the latest official firmware of P4 is v02.00.0700 and we're sorry that there is no beta for now. If you are experiencing the same ultrasonic sensor error on P4 in open filed, please kindly export the corresponding flight logs for analysis, thanks!

Hello DJI Susan. I have problem with ultrasonic sensor error. I'am using Phantom 4 Standard too. I can send flight logs for analysis. I have dat file from last 3 flights but i don't know how I can send file to DJI Support. Can I send you link on your PW for download rar file?

Hi DJI Susan ! Do you have any news from engineers about ultrasonic sensor error (Phantom 4 Standard) ?

Hi DJI Susan ! Do you have any news from engineers about ultrasonic sensor error (Phantom 4 Standard) ?

Sorry, I have not got any update for now. I'll push our engineers and keep you updated.

Hi DJI Susan. Do you have new informations from engineers? What kind is a problem with ultrasonic sensor error?

Hi DJI Susan. Do you have new informations from engineers? What kind is a problem with ultrasonic sensor error?

Sorry for keeping you waiting. According to the info you offered, it looks like the misinformation, our engineers are checking the exact status and see whether it can be figured out by the firmware update.

I have a P4 and have had the same message from day 2 of purchase and flights.. I have just sent the P4 in for repairs and or replacement.. Like others have mentioned you can turn off VPS but in my case i paid for a drone with VPS system and as long as its under warranty i'm going to try and get it repaired ... I have read NUMEROUS threads on this downward sensor issue/Ultrasonic issue. And DJI has done something about some AC's but not the P4 as of yet . I have a new V2.0 and this AC has been flawless ,,I am not kidding I'm so happy with this bird i take it everywhere i go even when i'm on my Harley i'll strap it to the rack just in case i see a place that looks cool to fly around in and take some pics. Now my P4 although it did fly great for the first week other then the sensor issue , i have lost all trust in because as soon as i did the FW update the ac just went to hell on me , Gimbal going limp every other time its powered on or VPS waring causing ac to buck mid air . just crazy stuff. I'm not sure how long it will take dji to do a fix on this Ultrasonic issue or downward sensor issue but for Gods sake please help!  That's my story and I'm sticking to it !    BUT all said and done they still make one of the best drones out there! Just a bit slow on bug fixes !

Good afternoon, I am more affected for months of the error of the ultrasound sensor. I still have the device, a phantom 4 pro in warranty, for which, I will finish sending it to the technical service. Before I would like to know how the beta firmware is working. it is a pity that these errors are occurring in these devices. On the last flight I got the error at 40 meters high. sorry for my English. I repeat, I would like to know if the beta firmware has solved this problem.Thank you.

Another question, in case of accessing and installing the beta firmware, would the drone remain under warranty in the event of such firmware failure? Thanks again

DJI Susan, can you help me?

Hi All,
Thank you so much for your patience!
I just got the latest news from our engineers that the misinformation Ultrasonic Sensor Error has been optimized in the latest beta firmware(V01.06.0100) of P4P.

Hi Reds2tall55, sorry for the inconvenience. As for the P4 issue, may I have the case number when you sent the unit in? I'd like to check the exact status and see whether we can help.

Sir, whether the beta firmware update is successful or failed will not affect the warranty. In case anything goes wrong, the designated team will do damage assessment and offer you a proper solution once received the package. If you are interested in the beta firmware, please kindly provide us with your DJI Account(the email address when you login DJI Assistant 2), we'll add you into the list, thanks!

Thanks DJI Susan, my account is igor_medrano@hotmail.com if it was necessary to send something else or if you see more advisable to send the drone to the technical service, I will communicate it. thanks for everything

Received with thanks! The beta will be available around 1-2 working days, you may have a try when received it. If the issue remains after updating to the beta successfully, you may consider sending the unit in for diagnosis at that time.
