Compass error - spark

[Jerry lim]

anyone facing this issue?
I had flew my spark earlier and everything was fine.
However during night time was trying to fly it near my apartment, the gps error msg keep popping out even I had recalibrated my compass.
After calibration, indicator in phone indicated green.
After takeoff my drone went hairwire and compass error appear again.
Anyone can help on this?
Calibration issue or faulty compass?
Thanks

Did you take off from a sidewalk or some other location that was potentially close to a magnetic metal object?

I takeoff besides the swimming pool at my apartment. Will this affect my compass or gps signal?
In fact this is not the first time that I fly at this area.

Re-Bar in the concrete will effect the compass

Yes, it could cause a problem.

Look at the aircraft symbol on the radar at the bottom, left corner of DJI GO. It should be pointing in the direction your Spark is facing when holding your Spark above the ground. When you set your Spark on the ground, it should still be pointing in the same direction. If you see the aircraft symbol spin on the radar, you'll know there is some kind of magnetic metal source nearby. The DJI GO app will sometimes alert you of this, but it doesn't always show a message.

I'm getting Compass Error all the time now, and failure when recalibrating. I'm going to contact DJI Monday and see if tech support can help. It seems to connect to GPS just fine, and fly normal, but I'm not going to try flying indoors in this condition.
