After replacing the screen on a Fold model, the main screen may appear off while the cover screen is on. This is normal and not a hardware failure before calibration.
Click steps to track your progress.
Fold the device and launch the Self Repair Assistant app on the cover screen.
Navigate to the digital hall sensor calibration screen.
Unfold the device and press the Volume Up or Volume Down button.
A vibration will confirm calibration is in progress.
