I just crashed my Phantom 3 Std. and it survived but it keeps saying Magnetic field interference
I've calibrated the compass and still doesn't calibrate..
Is there any quick way to fix it?

Have you double checked that the physical connections to the compass are still solid?

Have you tried an IMU calibration yet? I  had a friend  who had the same issue after a mild crash and he found that his IMU was "stuck". After he freed it and did the calibration it worked fine.

If you haven't tried Michgolden's advice, try that as well and see if that helps.

It sounds like the IMU may be stuck. It's kinda like a pendulum and if it's stuck it won't let you calibrate. There are videos on how to free it so I would suggest starting there.

Also make sure that the AC is sitting on a level surface when you run the IMU calibration.

Google had this on Magnetic Interference
If it's constant and won't go away like your pic that shows compass stuck at 0
Go to your Sensor settings in the app to see what it's showing for the compass.
If there are numbers there, you should be able to calibrate the compass but if it shows zero, the compass is not connected. Possibly the connector to the mainboard is loose or there is a broken wire in the landing gear. Have to open her up. Yes I been there cause my compas was getting the stuck error so I replaced it by replacing legs and all with compass from amazon

When you calibrate get away from everything including concrete. No watch, phone, or even keys with that auto unlock feature or an apple watch I've read. Hold level and rotate 360 degrees but go past where lights change color. Face down and rotate again till lights change. Gotta love this compass dance and where did they come up with this?????????

I opened it and it turn out to be that the compass was in fact disconnected...
And I got to turn it on...
But....
Surprise
I have a damaged motor, the smoke coming out of it told me...
So I hope it's only the motor

That is a bummer! One step at a time and next thing you know you'll be back in the air. At least you're learning the ins and outs of doing some repairs. That's always a plus.

Great prices, too! Even the normal price of of $18-22 isn't prohibitive, but the lower the better!  :-)

BTW, one caveat for you stendek:
The above links are to the newer "A" type motors which you probably already have, but just doublecheck to make sure you don't have the older motors.

VERY easy to tell the difference:

Curiously, the IMU video above uses a drone with the older motors.  :-)

Just a side note, double check rotation also before you order. Like hes got on there:  CW or  CCW.
