Check frame alignment and uniform folding before sealing the device.
Verify correct screen behavior when opening and closing the phone.

Very important:
On the Samsung Galaxy Z Flip 4, magnetic open and close system recalibration is strongly recommended after screen replacement. This process must be carried out using the official Samsung Self Repair Assistant software, with the device updated to the latest available Android firmware. Failure to perform this recalibration may cause flickering, delayed wake behavior, or erratic operation that does not indicate a defective screen.

Important about returns:
Returns will not be accepted for screens that have been installed or handled and show issues related to the magnetic opening and closing system caused by missing or incorrect calibration. These behaviors are not considered a screen defect but an incomplete installation procedure.

Notice

Service Pack screens are supplied with the latest firmware preinstalled. To ensure proper image, touch, and sensor performance, the device must be updated to the latest Android version before and after installation.
