Remove the screen.

Use tweezers to pick off the remaining adhesive on the case.

If you use isopropyl alcohol to clean the adhesive off the display, be sure to not let it splash onto any unintended components, as this can weaken their adhesive bond.

If you replaced the screen, check the screen's front-facing camera hole and remove any protective liners covering it.

If your replacement screen's display cable is held down by tape, remove the tape before installation.

If you are using a custom-cut adhesive, follow this guide to correctly apply new screen adhesive.

If you are using Tesa tape to reattach the screen, follow this guide.

During the boot-up process after reassembly, the screen will go through a calibration sequence. Do not touch the screen during this process, as it could result in improper touch calibration and create touch issues.
