I have same problem in my second phone, wont calibrate at all.
First phone worked great except had dead strip on rh screen.
First bv6000 had android 6 and calibrated compass quickly but this android 7 bv6000 wont.
I would love some help as if this phone is faulty I will be asking for money back.

Have a look at this post, although for Gyroscope, it contains info about the Compass.

Generally, it looks like some of the screws are magnetised, therefore disturbing the compass. The solution is to remove the screws close to the compass and get them demagnetized.

It seems some specimens have problems with magnetometer. This can't come from magnetized screw because there are dynamic disturbances in magnetometer's readout. There are some applications in the Google Play shop (like - let's see if this is the case. If so, 8-shape calibration won't bring great accuracy and each time you try, the north will be elsewhere. Even on the south... OS doesn't matter: mine BV6000 started with Android 6 and the compass is equally useless with Android 7. I'm afraid the magnetometer is soldered on the motherboard so no other replacement is possible than entire device (no one sells motherboards as far as I know).
