still no solution...

Which firmware version do you have?

I have the 2016 1011

Mine in 20170223. This difference may explain lack of gyroscope calibration option in your phone. Maybe Admin will be kind to check in the change log from which release this option is present. I think you have to upgrade your firmware to calibrate the gyroscope. Maybe you don't want to have newer one: but maybe 7.0 will write calibration data into the gyroscope and it will still be there after you downgrade... Only God and Admin know.

You can try the below ways: check if the screw magnetized

I FOUND THE PROBLEM!
the top left side screw got magnetized FOR SOME REASON and by removing the screw everything works perfect getting the screw near the hole drives the compass back to not working now i just want new side screws

The screws are magnetical and thats the problem with gyroscope.
If you are look on the screws, it's the top right screw.
If the screw fails, the gyroscope works much better.

The problem is, the ferromagetic screws affect magnetic field sensor used by compass, not the gyroscope that may be used by compass application too but for quick movement detection rather than for determinig direction. Wrongly biased gyroscope may then cause compass rotating and giving "low compass accuracy". Unfortunately, the magnetic field is periodically disturbed:



I rotated the phone by 90 degrees in about 1/3 where the Y (green) readout drops and Z (blue) rises. There are high drops on Z axis together with smaller on the X axis and negligible rises on Y axis. It might be that the steel screw amplifies the magnetic field. I suppose it comes from power lines. When the processor requires more power, the current rises, the electromagnetic field gets stronger and the disturbance peaks as high as the earth magnetic field (which is really weak in fact). It's possible that removing the steel screw stops amplifying these disturbances. If it was just magnetized, the readout would be affected statically and could easily be overcame by calibration by 8-shape waving of the device.

Then, if removing the screw really helps (still not having proper torx tools to try), the steel screw should be replaced with one made of different material that is not ferromagnetic. Like titan or duraluminium for example.

Please check the screw if magnetic
