Completely power off your device before you begin.

Apply a heated iOpener to the bottom edge of the device to loosen the adhesive underneath.

The display adhesive of the Galaxy Tab S7+ is extremely strong, and it's likely you need to reheat and reapply the iOpener several times before starting the display removal and during the removal procedure.

A hair dryer, heat gun, or hot plate may also be used, but be careful not to overheat the device.
