결론

If possible, turn on your phone and test your repair before installing new adhesive and resealing the phone.

The best way to secure the new screen is with a sheet of custom-cut double-sided tape. If the replacement part does not come with adhesive preinstalled apply tape to the back of the screen, then carefully feed the display cable through the frame. Align the screen and press it into place.

To reassemble your device, follow these instructions in reverse order.

Take your e-waste to an R2 or e-Stewards certified recycler.
