It is evident, however, that Apple favors Pantone color palettes.

• To ensure adhesive release, apply significant heat to the rear panel of the iPhone 8, having previously removed it carefully and without damage.
• Attempts to loosen the adhesive with heat are ineffective; the adhesive remains intact, while the metal frame may exhibit slight softening instead.
• Simulating a scenario involving a damaged display panel, we intentionally fractured one to assess the repair process; this exercise confirms that replacing a shattered panel presents a significantly greater challenge than handling an intact one, emphasizing the importance of preventing drops.
• Future attempts should consider increasing the applied temperature.
