During the display removal procedure, make sure all cables are placed underneath the phone and don't stick out to prevent damaging them.

Apply a heated iOpener to the screen to loosen the adhesive underneath. Apply the iOpener for at least 5 minutes.

The display adhesive of the Nothing Phone (1) is 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.
