Hello and good evening,

recently i bought a used Phantom 3 Standard drone, everything was fine for the first few flights had no problems at all, but one day while flying the drone started spinning around and flying up and down, after 1 minute it started the RTH and landed. Searching in Google i think i went through a high magnetic field, in fact they app , while this happened, was showing constant ' Compass Error'.
After that episode i'm not able to fly more than 20m height and 30m distance. I tried several fixes like FW Update, Remote reset, Remote Re-link with the AC, Recalibration on the compass, Recalibration of the IMU, none of them has fixed the problem.
Today i upgraded the 2 'Side Antennas' of the remote, still same problem...
Now my question is, should i replace the Compass and give it a try ?
Or should replace Wifi Receiver in the AC ?

Hello there YamiP3. I am sorry for the trouble this has caused and thank you for reaching out. Can you please fly your DJI Phantom 3 Standard to a different location with less interference to see if the issue will still persist and may we know what is the model of the mobile device you are using please? The said DJI drone might have picked up magnetic interference on the ground, and you took off from close to a buildings with rebar concrete metal objects on it. In addition, please make sure that the antennas are pointed toward the aircraft for optimal transmission. Thank you.

Hi,
Thanks for the response. I've tried several areas, unluckly with no results.
As a mobile device i'm using a Redmi Note 10 Pro.

Hi Yami,
What signal is lost after 30m distance and 20m height ? Controler- or/and wifisignal?
Did your phone cover any part of the RC upperside? If yes then try to put your phone on another place of the RC. This looks like a sending and receiving issue.the compass does ´nt need to be changed. But look for the antennas in the landing gear of the AC,that they are ok and properly connected to the board. Do it with the compass too.

The error Is i get Is Remote Controller signal weak, and then signal Lost... So it's the remote not wifi..the phone Is sitting in front of the RC away from the antennas...i'll Have a look at the cables on the RC and i'll come back..

Pictures of the inside regarding wifi cables and Compass...they look normal

Did you unplug your compass on purpose?
