After doing B and P pose calibration, why is the performance of the hands still bad when shown in VR?

The magnetic field was not stable when calibration was performed. Please remove all electronic devices which may magnetize the Hi5 VR Glove from your body and the surrounding area, e.g: cellphone, watch, computer, a table that is made of iron, magnet, high-current appliances, etc.
Please swing or rotate the glove slowly and observe the LED light. Check whether the LED light is flashing from every direction that you can see. If the light is always on but not flashing from a certain direction, it means the glove is experiencing electromagnetic interference or the glove is magnetized. Move somewhere far from the magnetic interference sources. Demagnetize the glove and perform the calibration process again.
You might not have calibrated properly. Re-calibrate with the B and P pose.
