Digital Hall Sensor Calibration (Fold and Flip Models Only)
Whenever the screen is replaced, the digital hall sensor must be calibrated to guarantee
optimized digital hall sensor performance for devices that have it.
Digital hall sensor calibration is available through the
Self Repair Assistant app.

This feature may not be available depending on the model. The availability of
this feature can be automatically checked in the Self Repair Assistant app, so
please follow the guidance of the Self Repair Assistant app.

For Fold models : If the main screen does not turn on after being replaced (the
main screen is off and the cover screen is on when the device is unfolded),
follow the steps below to perform digital hall sensor calibration. The boot
screen (the screen where the Samsung and carrier logos appear) will appear
normally and then turn off, so it is not a hardware failure.

screen.
2) Move to the digital hall sensor calibration screen, unfold the device, and
then press the Volume Up button or the Volume Down button.
3) You will hear a vibration, and the calibration will be performed
automatically.
When calibration is complete, the main screen will turn on normally.

main screen is off and the cover screen is on when the device is unfolded),

carrier logos appear) will appear normally and then turn off, so it is not a
hardware failure.
