A person attempts to repair a shattered Apple Watch Series 4 screen by replacing only the glass, a notoriously difficult and delicate process. They use specialized tools, such as a vacuum hot plate and a thin gold wire, to carefully separate the glass from the rest of the screen without damaging the underlying components. The process is tedious and requires great care, with the person noting that about 99% of people who attempt this repair will fail. After about three hours of work, the person successfully replaces the glass and tests the watch to ensure that all features, including touch sensitivity and force touch, are still functioning properly.
