Remove the screen.

During reassembly:

If you replaced your screen, check the front-facing camera hole and the sensor cutout on your replacement screen, and remove any remaining liners.

Check the frame for deformed grounding springs that stick straight up. These spring contacts should rise at a shallow angle. Use your finger to gently bend any deformed springs downward.

Remember to reinstall the display cable bracket.

This is a good point to test your phone before sealing it up. Temporarily connect your screen, power on your phone, and make sure it works as expected. Before continuing with reassembly, power off your phone and disconnect the screen.
