Remove the display.

Before installing the display, remove all traces of the old adhesive, then clean and prep the glued areas of the chassis and display (if you're re-using it) with isopropyl alcohol and a lint-free cloth.

Connect the display and power on the Essential Phone to test your repair before sealing the display panel in place.

You may re-secure the display with a strong double-sided adhesive tape, such as 1 mm Tesa 61395.
