Be sure to power off your phone before you begin.

A hair dryer, heat gun, or hot plate may also be used, but be careful not to overheat the phone—the AMOLED display and internal battery are both susceptible to heat damage.

Pull on the suction handle to create a gap between the rear glass and the frame.
Insert an opening pick into the gap.

Remove the rear glass.
Apply new adhesive where necessary after cleaning the relevant areas with isopropyl alcohol (>90%).
